- Like our Facebook: https://www.facebook.com/Petroleum.Industry - 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/Petroleum.Industry Twitter: https://twitter.com/Oil__Gas And Don't forget to subscribe to our channel

How Oil are Drilled? - Drilling Documentary - DOCS CHANNEL Drilling is a reducing procedure that utilizes a drill little bit to destroy or enlarge a gap of round cross-section in solid products. The drill bit is a rotary destroying device, typically multipoint. The little bit is pressed against the work surface and rotated at prices from hundreds to hundreds of transformations each minute. This compels the cutting side against the workpiece, cutting off chips (swarf) from the hole as it is pierced. Remarkably, specially-shaped bits can reduce holes of non-circular cross-section; a square cross-section is possible Drilling could influence the mechanical commercial properties of the work surface by producing low recurring stresses around the hole opening as well as an extremely thin layer of highly stressed and disrupted product on the freshly formed surface area. This creates the workpiece to come to be much more at risk to corrosion and fracture propagation at the worried surface area. A coating operation may be done to prevent these destructive conditions Subscribe to our channel: https://www.youtube.com/channel/UCqp3z8qbLBkiPWgfBtFadVA Visit our website for more info: http://worldgeographicchannel.com/

Geologists use seismic surveys to search for geological structures that may form oil reservoirs. The "classic" method includes making an underground explosion nearby and observing the seismic response that provides information about the geological structures under the ground. However, "passive" methods that extract information from naturally-occurring seismic waves are also known. The oil well is created by drilling a long hole into the earth with an oil rig. A steel pipe (casing) is placed in the hole, to provide structural integrity to the newly drilled well bore. Holes are then made in the base of the well to enable oil to pass into the bore.Finally a collection of valves called a "Christmas Tree" is fitted to the top, the valves regulate pressures and control flow. During the primary recovery stage, reservoir drive comes from a number of natural mechanisms. These include: natural water displacing oil downward into the well, expansion of the natural gas at the top of the reservoir, expansion of gas initially dissolved in the crude oil, and gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where the wells are located. Recovery factor during the primary recovery stage is typically 5-15%. While the underground pressure in the oil reservoir is sufficient to force the oil to the surface, all that is necessary is to place a complex arrangement of valves (the Christmas tree) on the well head to connect the well to a pipeline network for storage and processing. Sometimes pumps, such as beam pumps and electrical submersible pumps (ESPs), are used to bring the oil to the surface; these are known as artificial lift mechanisms. Over the lifetime of the well the pressure will fall, and at some point there will be insufficient underground pressure to force the oil to the surface. After natural reservoir drive diminishes, secondary recovery methods are applied. They rely on the supply of external energy into the reservoir in the form of injecting fluids to increase reservoir pressure, hence replacing or increasing the natural reservoir drive with an artificial drive. Secondary recovery techniques increase the reservoir's pressure by water injection, natural gas reinjection and gas lift, which injects air, carbon dioxide or some other gas into the bottom of an active well, reducing the overall density of fluid in the wellbore. Typical recovery factor from water-flood operations is about 30%, depending on the properties of oil and the characteristics of the reservoir rock. On average, the recovery factor after primary and secondary oil recovery operations is between 35 and 45%. The amount of oil that is recoverable is determined by a number of factors including the permeability of the rocks, the strength of natural drives (the gas present, pressure from adjacent water or gravity), and the viscosity of the oil. When the reservoir rocks are "tight" such as shale, oil generally cannot flow through but when they are permeable such as in sandstone, oil flows freely. The flow of oil is often helped by natural pressures surrounding the reservoir rocks including natural gas that may be dissolved in the oil (Gas oil ratio), natural gas present above the oil, water below the oil and the strength of gravity. Oils tend to span a large range of viscosity from liquids as light as gasoline to heavy as tar. The lightest forms tend to result in higher extraction rates. Petroleum engineering is the discipline responsible for evaluating which well locations and recovery mechanisms are appropriate for a reservoir and for estimating recovery rates and oil reserves prior to actual extraction.

The question of whether to drill for oil in the Arctic National Wildlife Refuge (ANWR) has been an ongoing political controversy in the United States since 1977. The issue has been used by both Democrats and Republicans as a political device, especially through contentious election cycles, and has been the subject of much debate in the National media. ANWR comprises 19,000,000 acres (77,000 km2) of the north Alaskan coast. The land is situated between the Beaufort Sea to the north, Brooks Range to the south, and Prudhoe Bay to the west. It is the largest protected wilderness in the United States and was created by Congress under the Alaska National Interest Lands Conservation Act of 1980.[4] Section 1002 of that act deferred a decision on the management of oil and gas exploration and development of 1,500,000 acres (6.1×109 m2) in the coastal plain, known as the "1002 area". The controversy surrounds drilling for oil in this subsection of ANWR. Much of the debate over whether to drill in the 1002 area of ANWR rests on the amount of economically recoverable oil, as it relates to world oil markets, weighed against the potential harm oil exploration might have upon the natural wildlife, in particular the calving ground of the Porcupine caribou. Prudhoe Bay Oil Field is a large oil field on Alaska's North Slope. It is the largest oil field in both the United States and in North America, covering 213,543 acres (86,418 ha) and originally containing approximately 25 billion barrels (4.0×109 m3) of oil.[1] The amount of recoverable oil in the field is more than double that of the next largest field in the United States, the East Texas oil field. The field is operated by BP; partners are ExxonMobil and ConocoPhillips Alaska.

For more information on investing in upcoming oil and gas wells with Patriot Energy, visit us online at http://www.patriotenergy.com or call (469) 269-5414 and ask to speak to one of our consultants. To view this video on our website and read the full video transcription, visit http://www.patriotenergy.com/media/patriot-energy-rig-site-drilling-process/ Video Transcription (Partial): This is a Patriot Energy drilling rig site in the Permian Basin in West Texas. This well will be drilled to a total depth of about 8,900 feet, then it will be logged and eventually fracked. Here, you’ll see what the drilling and logging looks like, then in a separate video, we’ll go through the entire fracking process at another well. This well had been drilling for a couple weeks when our camera showed up to capture the well hitting total depth. Here’s how it works… There are 3 crew shifts, working around the clock until drilling is complete. They drill rain or shine, and in fact the rig itself is triple grounded, so even lightning is not a threat. The main position on the platform is the driller. He runs the controls, maintains the written logs and basically directs the show. He’s the guy in charge as far as the drilling is concerned. But really, rig crews work so cohesively, that there is very little discussion, often just occasional sign language to guide a pipe or a chain into place. There are many moving parts on the rig, once it's set up. Here, for example, they’re mixing drilling mud. You could have all the latest technology in the world, but without drilling mud, the whole operation would come to a halt. Mud serves several purposes besides lubrication. Mud engineers constantly monitor the drilling mud as it circulates out of the well and they can tell what’s going on down the hole from what comes up out of the hole. This tank is where the water is circulated and flows out of the well, and is where it is filtered and is pumped back into the hole. Large generators power the rig’s electrical needs and a massive diesel engine drives the motor that powers the bit. This is where all the action happens, the drilling platform. If you visited a rig site anywhere in the world, most of the time it would look about like this: Pipe spinning at about 45 – 50 RPM and not much else going on. That weight above the pipe keeps enough pressure on the bit and keeps the drilling process moving methodically. Each section of drilling pipe is about 35 feet long, and takes anywhere from about – say - 20 minutes…up to an hour and a half to drill the length of one pipe. The difference is obviously what they’re drilling through at any given time. Sandstone goes fast. Shale grinds down to a trickle. Once a section of pipe is getting close to the end, the driller suspends the weight and the bit stops its progress. That’s when the action begins. The driller and roughnecks man the rig floor and go to work. First, the Kelly Drive is moved over and lifted up to where it connected to the last pipe. Large tongs are used to break the seal, then the driller uses back pressure to unscrew the pipe. Then the Kelly drive is connected to the next section of pipe – which is sitting off to the side in a rat hole, which is just a shallow queue-up hole that gets poked into the ground when the rig is set up. Then that section of pipe is raised up into the rig tower and lowered to match the previous section that is just sticking up out of the rotary drive area. The Tongs are once again used to seal this tightly, then the string is in position for the next section of pipe. The master bushing is lowered into position, traveling block and swivel are engaged, the RPMs are dialed in to proper speed. Now, the next section of pipe begins making its way down the hole. If you figure 8,00 feet depth for this hole, at 35-feet per pipe, this process will take place around 230 times – day and night – before finally the graph that shows exactly where the drill bit is beneath the surface – reaches it’s destination. At that point, things really begin to shift. First, the hole is flushed out with circulating water for a period of several hours. At that point, all the pipe is pulled….or tripped….out of the hole. Then, a logging crew arrives and they begin a multi-hour process of connecting probes and wires that will begin the computerized logging analysis of the well.

Rotary drilling is characterized as a method of drilling that employs a sharp, rotational drill bit to bite its way through the earth’s crust. One of the most effective and common methods of drilling, it is used in the construction, mining, and oil industries for its ability to cut through even the most challenging and hardest formations. The rotary drill rig consists of a prime mover, hoisting equipment, rotating equipment and circulation equipment, all of which perform tasks crucial to drilling a well or hole. With the help of pneumatics, hydraulics or an electric motor, high torque and rotation are transmitted from the prime mover to the drill, which sits on a mast above the hole. Rotary drilling was first used for drilling oil wells in 1901 when Captain Anthony Lucas and Patillo Higgins applied it to their Spindletop well in Texas. By 1925, the rotary drilling method was improved with the use of a diesel engine. The first attempt at rotary drilling involved a device that sent a stream of water down a hollow shaft of the drill to remove cuttings. This was in contrast to the cable drill, whereby the operation is interrupted and cuttings are removed singularly before the drilling can resume. The early rotary drill was originally used for drilling in softer formations in areas such as California and the Gulf Coast; but this changed with the production of roller and cone bits comprising steel alloy. This addition made rotary drilling suitable for harder formations, such as rock, and it was eventually used for boring deep holes and wells. Rotary drilling became valuable to the oil industry because it was able to produce holes of a smaller diameter than cable drilling. This became possible because a hole produced by a rotary drill was the same diameter at the lower end as it was at the top. Rotary drilling provided many improvements to drilling applications. The nature of the rotary drill proved important when oil well cements were being produced. The process of unloading continuous sacks of cement to construct a well required the drilling techniques of the rotary drill, which could accommodate these new materials. Early oil drilling applications that were completed with cable tools or churn drills were laden with problems, such as erupting oil fountains that resulted in fires and the loss of valuable oil. The issues that arose from the high pressure of oil wells were remedied with the use of rotary drilling.
