Suction line (#3) is an intake line for the mud pump to draw drilling fluid from the mud tanks. Swivel (#18) is the top end of the kelly that allows the rotation of the drill string without twisting the block. Traveling block (#11) is the moving end of the block and tackle. Together, they give a significant mechanical advantage for lifting.
In other words, a tool designed to drill directionally with continuous rotation from the surface, eliminating the need to "slide" a mud motor. The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [ 1 ] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for ...
A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor which is transferred as ...
Mud flow volume; Mud Motors. Use of this information can allow the operator to drill the well more efficiently, and to ensure that the MWD tool and any other downhole tools, such as a mud motor, rotary steerable systems, and LWD tools, are operated within their technical specifications to prevent tool failure. This information is also valuable ...
M712 Copperhead approaches an old M47 Patton tank used as a target M712 detonating. The M712 Copperhead is a 155 mm caliber cannon-launched guided projectile.It is a fin-stabilized, terminally laser guided, explosive shell intended to engage hard point targets such as tanks, self-propelled howitzers or other high-value targets.
A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling.
Mud is a vital part of drilling operations. It provides hydrostatic pressure on the borehole wall to prevent uncontrolled production of reservoir fluids, lubricates and cools the drill bit, carries the drill cuttings up to the surface, forms a "filter-cake" on the borehole wall to prevent drilling fluid invasion, provides an information medium for well logging, and helps the drilling by ...
1" (5 foot average) mud log showing heavy (hydrocarbons) (large area of yellow)Mud logging includes observation and microscopic examination of drill cuttings (formation rock chips), and evaluation of gas hydrocarbon and its constituents, basic chemical and mechanical parameters of drilling fluid or drilling mud (such as chlorides and temperature), as well as compiling other information about ...
