CITHP – closed-in tubing head pressure (tubing head pressure when the well is shut in) CIV – chemical injection valve; CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system) CL – core log; CLG – core log and graph; CM – choke module
Moon pool: A space beneath the drill floor of an offshore rig open to the water below. Motorman: Responsible for maintaining all equipment on the rig to ensure smooth operation and minimal downtime. Mouse hole: A hole on the drilling rig floor used to hold the next joint of pipe to be added to the drill string. Mud: Slang term for drilling ...
Illustration of surface casing vent flow and gas migration pathways in the subsurface near a producing well. The cement plug in the lower portion of the well makes this an example of an abandoned well. Policies regulating reporting of fugitive gas emissions vary, and there is often an emphasis on self-reporting by companies.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
The term "subsea" (SS) by itself should not be used, as it is ambiguous. It could mean: below sea floor or bottom, below mean sea level (MSL), below lowest astronomical tide (LAT), etc. The acronym TVDSS is commonly used in the oil industry to represent TVD minus the elevation above mean sea level of the depth reference point of the well.
The leak is releasing up to 110,000 pounds of gas per hour. An underground well-casing might have failed, pushing the pressurized gas to the surface. Severe natural gas leak in Los Angeles County ...
The leachate drainage system is responsible for the collection and transport of the leachate collected inside the liner. The pipe dimensions, type, and layout must all be planned with the weight and pressure of waste, and transport vehicles in mind. The pipes are located on the floor of the cell.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
