Oil Drilling | Oil & Gas Animations
 
08:22
- Like our Facebook: https://www.facebook.com/oilvips - Geologists and geophysicists have agreed on the existence of a "prospect", a potential field. In order to find out if hydrocarbons are indeed trapped in the reservoir rock, we must drill to hit them. Bearing in mind the knowledge acquired about the substratum and the topography of the land, the best position for the installation of the drilling equipment is determined. Generally it is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. The drillers then make a hole in conditions that are sometimes difficult. Of small diameter (from 20 to 50 cm) this hole will generally go down to a depth of between 2000 and 4000 meters. Exceptionally, certain wells exceed 6000 m. One of them has even exceeded 11 000 m! Certain fields can be buried at a depth equivalent to the height of 12 Eiffel Towers ... The derrick is the visible part of the drilling rig. It is a metal tower several tens of meters high. It is used to vertically introduce the drill strings down the hole. These drill strings are made up of metallic tubes screwed end to end. They transmit a rotating movement (rotary drilling) to the drilling tool (the drill bit) and help circulate a liquid called "mud" (because of its appearance) down to the bottom of the well. The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an assembly of three cones -- from which comes the name "tri cone" -- in very hard steel, which crushes the rock. Sometimes when the rock being drilled is very resistant, a single- block tool encrusted with diamonds is used. This wears down the rock by abrasion. Through the drill pipes, at the extremity of which the drill bit rotates, a special mud is injected, which the mud engineer prepares and controls. This mud cools the drill bit and consolidates the sides of the borehole. Moreover it avoids a gushing of oil, gas or water from the layer being drilled, by equilibrating the pressure. Finally, the mud cleans the bottom of the well. As it makes its way along the pipes, it carries the rock fragments (cuttings) to the surface. The geologist examines these cuttings to discover the characteristics of the rocks being drilled and to detect eventual shows of hydrocarbons. The cuttings, fragments of rock crushed by the drill bit, are brought back up to the surface by the mud. To obtain information on the characteristics of the rock being drilled, a core sample is taken. The drill bit is replaced by a hollow tool called a core sampler, which extracts a cylindrical sample of several meters of rock. This core supplies data on the nature of the rock, the inclination of the layers, the structure, permeability, porosity, fluid content and the fossils present. After having drilled a few hundred of meters, the explorers and drillers undertake measurements down the hole called loggings, by lowering electronic tools into the well to measure the physical parameters of the rock being drilled. These measures validate, or invalidate, or make more precise the hypotheses put forward earlier about the rocks and the fluids that they contain. The log engineer is responsible for the analysis of the results of the various loggings. The sides of the well are then reinforced by steel tubes screwed end to end. These tubes (called casings) are cemented into the ground. They isolate the various layers encountered. When hydrocarbons are found, and if the pressure is sufficient to allow them come to the surface naturally, the drillers do a flow check. The oil is allowed to come to the surface during several hours or several days through a calibrated hole. The quantity recovered is measured, as are the changes in pressure at the bottom of the well. In this way, a little more knowledge is gained about the probable productivity of the field. If the field seems promising, the exploration team ends the first discovery well and goes on to drill a second, even several others, several hundred or thousand meters further away. In this way, the exploration team is able to refine its knowledge about the characteristics of the field. The decision to stop drilling is made only when all these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production. --------------------------------------------------------------------------------------- Like our Facebook: https://www.facebook.com/oilvips Twitter: https://twitter.com/oilvips And Don't forget to subscribe to our channel

Environmental Dynamics and Exposure Pathways of Subsurface Contaminants - Part 1
 
02:02:39
Through a series of complementary topical sessions, explore scientific issues concerning transport, transformation, and exposure pathways of subsurface contaminants, such as metals, organics, and radionuclides. Examples from a wide range of potential applications include waste site management decision-making, characterizing the spread of contaminants from abandoned mines, and pollution prevention planning for energy development. This session focused on the complex chemistry of the subsurface environment and how it affects contaminant transport. A specific example was considered to illustrate the use of advanced synchrotron and other techniques to elucidate mechanisms and inform decision makers. The topic of how molecular-level information and small-scale models can be incorporated into larger-scale transport models was discussed.

When they saw that Sweden’s City of Kiruna couldn’t coexist with the iron mine that lies beneath, city planners had a daring idea. Moving the city 3 kilometers east would save the mining industry and give citizens a chance to reimagine their city. When an executive at IT services company CGI saw a way to collect extensive infrastructure data to support smart, sustainable growth, his team collaborated with the city on a proof of concept. By “seeing” city infrastructure data with Microsoft HoloLens—from pipe material types to subsurface composition data like soil type, Kiruna planners have a leg up on the future.

GOLD PROSPECTING TIPS  .. GOLD RUNNERSS
 
01:56
gold prospecting in america is bac Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment.[1] The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling.[2] Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.[4] Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their sources.Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies.[5] Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits.[6] Gold mining in Alaska Gold in California Gold nugget Gold panning Gold Prospectors Association of America Gold rush Hushing Mineral exploration Placer mining Recreational gold mining

Geotechnical engineering is important in civil engineering, but also has applications in military, mining, petroleum and other engineering disciplines that are concerned with construction occurring on the surface or within the ground. Geotechnical engineering uses principles of soil mechanics and rock mechanics to investigate subsurface conditions and materials; determine the relevant physical/mechanical and chemical properties of these materials; evaluate stability of natural slopes and man-made soil deposits; assess risks posed by site conditions; design earthworks and structure foundations; and monitor site conditions, earthwork and foundation construction.A typical geotechnical engineering project begins with a review of project needs to define the required material properties. Then follows a site investigation of soil, rock, fault distribution and bedrock properties on and below an area of interest to determine their engineering properties including how they will interact with, on or in a proposed construction. Site investigations are needed to gain an understanding of the area in or on which the engineering will take place. Investigations can include the assessment of the risk to humans, property and the environment from natural hazards such as earthquakes, landslides, sinkholes, soil liquefaction, debris flows and rockfalls. A geotechnical engineer then determines and designs the type of foundations, earthworks, and/or pavement subgrades required for the intended man-made structures to be built. Foundations are designed and constructed for structures of various sizes such as high-rise buildings, bridges, medium to large commercial buildings, and smaller structures where the soil conditions do not allow code-based design. Foundations built for above-ground structures include shallow and deep foundations. Retaining structures include earth-filled dams and retaining walls. Earthworks include embankments, tunnels, dikes and levees, channels, reservoirs, deposition of hazardous waste and sanitary landfills. Geotechnical engineering is also related to coastal and ocean engineering. Coastal engineering can involve the design and construction of wharves, marinas, and jetties. Ocean engineering can involve foundation and anchor systems for offshore structures such as oil platforms. The fields of geotechnical engineering and engineering geology are closely related, and have large areas of overlap. However, the field of geotechnical engineering is a specialty of engineering, where the field of engineering geology is a specialty of geology. Coming from the fields of engineering and science, respectively, the two may approach the same subject, such as soil classification, with different methods.

Subsidence - Video Learning - WizScience.com
 
02:09
"Subsidence" is the motion of a surface as it shifts downward relative to a datum such as sea-level. The opposite of subsidence is uplift, which results in an increase in elevation. Ground subsidence is of concern to geologists, geotechnical engineers and surveyors. Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface causes the creation of voids . If the roof of these voids becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface. This type of subsidence can result in sinkholes which can be many hundreds of meters deep. Several types of sub-surface mining, and specifically methods which intentionally cause the extracted void to collapse will result in surface subsidence. Mining-induced subsidence is relatively predictable in its magnitude, manifestation and extent, except where a sudden pillar or near-surface underground tunnel collapse occurs . Mining-induced subsidence is nearly always very localized to the surface above the mined area, plus a margin around the outside. The vertical magnitude of the subsidence itself typically does not cause problems, except in the case of drainage –rather, it is the associated surface compressive and tensile strains, curvature, tilts and horizontal displacement that are the cause of the worst damage to the natural environment, buildings and infrastructure. Where mining activity is planned, mining-induced subsidence can be successfully managed if there is co-operation from all of the stakeholders. This is accomplished through a combination of careful mine planning, the taking of preventive measures, and the carrying out of repairs post-mining.

KEENE 140 DRYWASHER Gold in Wickenburge Arizona . GOLD RUNNERSS
 
02:10
KEENE DRYWASHER Gold in Wickenburge Arizona . GOLD RUNNERSS the dirt was wet or els our results would have been amazing Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment.[1] The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling.[2] Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.[4] Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their source Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies.[5] Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits.[6] where to find gold, how to find gold, minerals, mineral identification, gold mine, gold, the mine, mining gold, how do i find gold, rocks and minerals gold bug 2 mine lab garret Gold mining in Alaska Gold in California Gold nugget Gold panning Gold Prospectors Association of America Gold rush Hushing Mineral exploration Placer mining Recreational gold mining little san domingo wash lynx lake

Multi-contaminant interactions at aquifer-river interfaces
 
47:04
Presented by Stefan Krause - Professor and Chair or Ecohydrology and Biogeochemistry at the University of Birmingham, UK - at the 2018 Emerging Contaminants in the Aquatic Environment Conference. Hyporheic zones at the interfaces between aquifers and rivers are characterized by the spatially and temporally dynamic mixing of groundwater and surface water resources. The mixing of these diverse water sources creates streambed hotspots where different types of legacy and emerging contaminants meet, potentially react or compete for reaction partners. This demands the development of integrated management strategies for groundwater and surface water resources. This talk investigates the organizational principles of drivers and controls of multiple contaminant interactions in hyporheic zones, including examples of different diffuse and point source legacy pollutants as well as emerging contaminants such as engineered nanoparticles and microplastics. The environmental impacts of multiple pollutants on ecosystem functioning (whole stream metabolism, biofilm primary production) are furthermore analyzed in relation to other stressors, such as increasing water temperatures, flood or drought conditions.
What is Irrigation ? And necessity Of Irrigation
 
05:40
The hub of a center-pivot irrigation system Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection,[1] suppressing weed growth in grain fields[2] and preventing soil consolidation.[3] In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming. Irrigation systems are also used for cooling livestock, dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the removal of surface and sub-surface water from a given area. #irrigation #irrigationengineering #educationalvideo #civilengineering #education

Bio-Geo-Alchemy: Biogeotechnical Carbonate Precipitation - 2016 Buchanan Lecture by E. Kavazanjian
 
02:43:57
"Bio-Geo-Alchemy: Biogeotechnical Carbonate Precipitation for Hazard Mitigation and Ground Improvement" Presented October 14, 2016 by Edward Kavazanjian, Jr., Ph.D., P.E., D.GE, NAE Begins at 1:14:28 Also presented: 2015 Terzaghi Lecture, "The Evolution of Specialty Geotechnical Construction Techniques" by Donald Bruce, Ph.D., C.Eng, L. G., L.E.G.,. D.GE, M.ASCE Begins at 7:00 Program: https://ceprofs.civil.tamu.edu/briaud/Buchanan%20Web/Twenty-Fourth%20Buchanan%20Lecture%20Booklet.pdf While the ancient alchemists strove to change lead into gold, modern day bio-geo-alchemists strive to turn sand into sandstone. The bio-geo-alchemy technology that has gained the most attention over the past 15 years is bio-mediated calcium carbonate precipitation hydrolysis of urea (ureolysis), wherein microbes are used to induce precipitation of calcium carbonate (preferably calcite) in granular soils, turning cohesionless sand into a sandstone-like material. More recent research has looked at using other microbially-mediated processes (e.g., reduction of nitrogen, or denitrification) and bio-inspired ureolysis using an agriculturally-derived enzyme to precipitate carbonate in soil. Successes in laboratory testing and limited field trials suggest that these techniques can non-disruptively mitigate the potential for earthquake-induced liquefaction under and around existing facilities, control fugitive dust, and replace Portland cement as a binder in a variety of infrastructure construction applications. Induced carbonate precipitation is just one of many technologies currently being explored in the emerging field of biogeotechnical engineering, including development of root-inspired earth reinforcement and foundation systems, in situ creation of barriers to contaminant transport, soil and groundwater contaminant transformation or sequestration, enhanced soil penetration systems, and motile subsurface investigation probes.

THE AQUA-MISSION TECHNOLOGY
 
02:26
http://eawctechnologies.com/index.php/en/water Aqua-mission is a world-wide unique humidity extraction system based on long-tested mining Air conditioning technology. The basic idea was inspired by air-conditioning facilities used in coal mines; where large quantities of hot air had to be cooled down to improve working conditions. On the one hand, technology used for mining had to be compact, durable, of great mobility and very easy to handle. On the other hand, it had to provide enough cooling power to cool down coal mines of enormous size. This exceptional performance was achieved in the design of a highly efficient heat exchanger, the spiral heat exchanger, which forms the basis for huge water extraction potential. The spiral heat exchanger became the heart of aqua-mission.
