How do you drill a oil well
Two main techniques are used to drill oil wells today. In horizontal drilling, the idea is to extract oil that happens to be oriented in a mostly sideways direction in relation to the ground. This is the situation most commonly observed in rock shale because of the way the rock itself forms (it tends to fracture sideways under high pressure). How oil and gas wells are drilled, produced, and abandoned. Surface and subsurface environmental concerns are described, including the protection of fresh waters and drilling in urban areas. 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. There are two stages of drilling: 1. running and cementing of cases and 2. drilling until the bit reaches the depth of the targeted zone. Each drill bit typically lasts 4,500 – 6,500 feet of drilling. Replacing the bit requires the removal of the entire string of drill pipe in a process called “tripping out”. Drilling on land is an undertaking on its own. How do you drill in lightless ocean depths and transport all that liquid, gas and solid petroleum back to the surface? How do you keep from polluting the ocean? And how do you do all of this, with tons of special equipment, in the middle of rough seas? The well is created by drilling a hole 12 cm to 1 meter (5 in to 40 in) in diameter into the earth with a drilling rig that rotates a drill string with a bit attached. After the hole is drilled, sections of steel pipe (casing), slightly smaller in diameter than the borehole, are placed in the hole.
11 Dec 2012 Drilling fluid, known as mud, has several different functions essential to drilling an oil or gas well, including. – Subsurface pressure control.
Oil 101 - Drilling the Well - Upstream Oil and Gas - This Oil 101 Drilling Fundamentals module is part of our complete 'Microbes to Markets' Oil 101 course. Drilling is a process whereby a hole is bored using a drill bit to create a well for oil and natural gas production. There are various kinds of oil wells with different functions: Exploration wells (or wildcat wells) are drilled for exploration purposes in new areas. The location of the exploration well is determined by geologists. Decide how you want to drill the well. Most wells are drilled out, but wells may also be dug or driven, if conditions warrant. Drilled wells may be bored with an auger or rotary tool, smashed out with a percussion cable or cut … How Oil And Gas Wells Are Drilled Horizontally. Today's oil companies now have the ability to drill wells sideways, to reach specific pockets of oil and gas or "targets" which may be beneath cities or environmentally sensitive area where a rig cannot be set up. After all, if oil is $40 a barrel, but they're pumping out 35 billion barrels a year well that doesn't sound like a bad payoff to you and me. But that's before you take into account how far oil companies have to drill for oil. Did you ever wonder how far down they actually drill? I guarantee it's a lot further than you think. Take a look
Drilling Mud Drilling fluid, known as mud, has several different functions essential to drilling an oil or gas well, including – Subsurface pressure control – Cuttings removal and transport to the surface – Suspend solids – Helps suspends weight of the drillstring and casing – Lubrication & cooling of the drillstring & bit
Pad sites allow multiple wells to be drilled from one surface lease, thereby reducing the total surface area required for oil and gas development. Once drilling is
