A pressure gauge, typically run on slickline, used to measure and record downhole pressure. Downhole gauges are commonly used in assessing the downhole pressure under various flowing conditions, the basis of pressure transient analysis.
Industry:Oil & gas
A portion of proceeds from production, specified by contract, and payable to the lessor or farmor, or host country until total payment has reached a predetermined limit specified by contract.
Industry:Oil & gas
A portion of produced oil that the operator applies on an annual basis to recover defined costs specified by a production sharing contract.
Industry:Oil & gas
A positive-displacement reciprocating pump that is configured with three plungers. Triplex pumps are the most common configuration of pump used in both drilling and well service operations. Pumps used in well service activities generally are capable of handling a wide range of fluid types, including corrosive fluids, abrasive fluids and slurries containing relatively large particulates.
Industry:Oil & gas
A precisely machined test device, typically fabricated from steel or similar durable material, having a specified internal or external diameter. The gauge ring is used to confirm the dimensional compatibility of tools and equipment that must pass through restrictions of a certain diameter.
Industry:Oil & gas
A presentation of the acoustic waveform at a receiver of a sonic or ultrasonic measurement, in which the amplitude is presented in color or the shades of a gray scale. The variable-density log is commonly used as an adjunct to the cement-bond log, and offers better insights into its interpretation; in most cases microannulus and fast-formation-arrival effects can be identified using this additional display. In openhole, it may be displayed alongside the sonic log transit-time as a qualitative presentation of the acoustic wave train, and is sometimes used for fracture detection by examination of the chevron patterns given by Stoneley wave reflections (and other wave reflections) at fractures crossing the borehole.
Industry:Oil & gas
A prediction of the amount of production that will occur from a well, reservoir or field. This estimate is sometimes expressed as a fraction of the total hydrocarbons originally in place.
Industry:Oil & gas
A portion of land that contains separators, treaters, dehydrators, storage tanks, pumps, compressors and other surface equipment in which fluids coming from a well are separated, measured or stored.
Industry:Oil & gas
A polished bore designed to accept a seal assembly, such as may be used in a permanent production packer.
Industry:Oil & gas
A polymer with a high molecular weight. The basic repeating unit or monomer of polyacrylamide is a combination of carbon, hydrogen, oxygen and nitrogen. Polyacrylamides increase the viscosity of the water slug that precedes the final water injection. Polyacrylamides are frequently used as mobility-control buffers in micellar-polymer flooding operations.
