The numerical designation assigned to offshore lease and license tracts, or subdivisions of the tracts
A contract with diverse owners of separately leased oil and gas tracts that enables an oil company to drill one or two test wells instead of one well per tract
An area subdivision of the UKCS of 10 minutes of latitude by 12 minutes of longitude measuring approximately 10 x 20 kms, forming part of a quadrant. Each quadrant is divided into a grid five blocks wide and six deep, and numbered 1 to 30 from NW to SE (e.g. Block 9/13 is the 13th block in Quadrant 9).
Refers to an oil and gas limited partnership which has not committed to specific prospects, leases, or properties at the time of capital formation
A mixture of crude oils, blended in the pipeline to create a crude with specific physical properties. Because heavy and extra-heavy crudes or bitumens cannot flow from the field to the refinery in their original state and at normal surface temperatures, they are blended with lighter crude oils primarily to reduce viscosity, thereby enabling transportation to a refinery
A core sample of rock so highly permeable and saturated that oil drips from it.
A device for guaranteeing that during bleeding, the gas is exhausted away from the well head zone
To drain off liquid or gas, generally slowly, through a valve called a bleeder. To bleed down, or bleed off, means to release pressure slowly from a well or from pressurized equipment
Complete interruption of power in a given service area
Certain generators have the ability to black start, meaning they can restart their generation plant with no electrical input if the system has blacked out. Generators without this capability require power from the grid to restart their generating plant
