Tripping (pipe)
{{unreferenced, date=January 2015 Tripping pipe (or "Making a round trip" or simply "Making a trip") is the physical act of pulling the drill string out of the wellbore and then running it back in. This is done by physically breaking out or disconnecting (when pulling out of the hole) ''every other 2 or 3 joints of drill pipe'' at a time (called a stand) and racking them vertically in the derrick. When feasible the driller will start each successive trip on a different "break" so that after several trips fresh pipe dope will have been applied (when running back in the hole) to every segment of the drill string. The most typical reason for tripping pipe is to replace a worn-out drill bit. Though there are many problems that occur to warrant the tripping of pipe. Downhole tools such as MWD (measurement while drilling), LWD (logging while drilling) or mud motors break down quite often. Another common reason for tripping is to replace damaged drill pipe. It is important to get the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HWDP Part
CHWDP or HWDP is a frequently used Poland, Polish Acronym, acronym or initialism of the Polish language, Polish phrase ''chuj w dupę policji'', literally meaning "(put a) dick in the police's ass." This anti-authoritarian and anti-police slogan, often written on walls in Poland, is used as a vulgar form of provocation against the police and authorities. The initialism was largely popularised by Polish hip hop music and Anarchism in Poland, Polish anarchists, where it is often used in lyrics and as graffiti. It is a specific expression of protest against the authorities, and against "the system" in general. It is more or less analogous to the English language expressions ''ACAB'' and “''fuck the police''”. In Polish orthography, Ch (digraph), Ch is a digraph. However as ''chuj'' is pronounced the same as ''huj'', the acronym HWDP is commonly seen. Popularity The slogan is already very widespread in Poland, and its popularity is spreading to other countries, most notably ...

Oilfield Terminology
Oilfield terminology refers to the jargon used by those working in fields within and related to the upstream segment of the petroleum industry. It includes words and phrases describing professions, equipment, and procedures specific to the industry. It may also include slang terms used by oilfield workers to describe the same. Examples *Bell nipple: An enlarged pipe at the top of a casing string that serves as a funnel to guide drilling tools into the top of the well. *Big bear: A big bear is a hitch (see hitch) that lasts a minimum of 50 straight days. *Black Leg : Joints of pipe racked back in the derrick. * Blowout: A sudden, uncontrolled release of underground pressure from the well. *BOP (Blowout preventer): Pronounced "B-O-P", not "bop", is a mechanical device connected to the wellhead to control and prevent blowouts. *Catwalk: Elevated platform used for sliding pipe up to the rig floor. *Chainhand (also motorman): An experienced laborer capable of maintaining most part ...

Well Logging
Well logging, also known as borehole logging is the practice of making a detailed record (a ''well log'') of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (''geological'' logs) or on physical measurements made by instruments lowered into the hole (''geophysical'' logs). Some types of geophysical well logs can be done during any phase of a well's history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies. Wireline logging The oil and gas industry uses wireline logging to obtain a continuous record of a formation's rock properties. Wireline logging can be defined as being "The acquisition and analysis of geophysical data performed as a function of well bore depth, together with the provision of related services." Note ...

Chinese Fingercuffs
A Chinese finger trap (also known as a Chinese finger puzzle, Chinese thumb cuff, Chinese handcuffs, and similar variants) is a practical joke device, gag toy used to play a practical joke on unsuspecting children and adults. The finger trap is a simple puzzle that traps the victim's fingers (often the index fingers) in both ends of a small cylinder woven from bamboo. The initial reaction of the victim is to pull their fingers outward, but this only tightens the trap. The way to escape the trap is to push the ends toward the middle, which enlarges the openings and frees the fingers. The single-ended version, sold as a "girlfriend trap", has been available since at least 1870, when it was recorded as a "Mädchenfänger" or "girl catcher". Design The tightening is simply a normal behavior of a cylindrical, helically wound braid, usually the common biaxial braid. Pulling the entire braid lengthens and narrows it. The length is gained by reducing the angle between the warp and we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mud Motor
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 concentric power to the drill bit. The mud motor uses different rotor and stator configurations to provide optimum performance for the desired drilling operation, typically increasing the number of lobes and length of power assembly for greater horsepower. In certain applications, compressed air, or other gas, can be used for mud motor input power. Normal rotation of the bit while using a mud motor can be from 60 rpm to over 100 rpm. Basic principle Based on the principle developed by Rene Moineau, the theory states that a helical rotor with one or more lobes will rotate eccentrically when the stator contains more lobes than the rotor. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill Bit
Drill bits are cutting tools used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the ''shank'' in the chuck. Drills come in standardized drill bit sizes. A comprehensive drill bit and tap size chart lists metric and imperial sized drills alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section. Characteristics Drill geometry has several characteristics: *The spiral (or rate of twist) in the drill bit controls the rate of chip removal. A fast spiral (high twist rate or "compact flute") drill bit is used in high feed rate applications under low spindle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill String
A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the Well drilling#Drill bits in mechanical drilling, drill bit. The term is loosely applied to the assembled collection of the smuggler pool, drill collars, tools and drill bit. The drill string is hollow so that drilling fluid can be pumped down through it and circulated back up the Annulus (oil well), annulus (the void between the drill string and the casing/open hole). Drill string components The drill string is typically made up of three sections: * Bottom hole assembly (BHA) * Transition pipe, which is often heavyweight drill pipe (HWDP) * Drill pipe Bottom hole assembly (BHA) The Bottom Hole Assembly (BHA) is made up of: a drill bit#Well drilling bits, drill bit, which is used to break up the rock Geologic formation, formations; drill collars, which are heavy, thick-walled tubes used to apply we ...
