the inside annulus;tubing-by-production casing annulus. (Note, there may be regional differences in the A, B, C annulus designations and some are reversed. Inside annuli (IA) and outside annuli (OA) are more universally descriptive.)

n: A rig drived by DC which is commutated by SCR.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

n: a roller cone bit that is specially designed for air or gas drilling. It is very similar to a regular bit, but features screens over the bearings to protect them from clogging with cuttings and thicker hardfacing on the shirttail to protect them from abrasive, high-velocity air or gas drilling fluid.

straight or branched chain hydrocarbons with single bonded carbon atoms. Describes most oils.

a patented screen design that allows gravel packing slurry to flow past an annular bridge point that would normally stop the placement of gravel.

Kerogen that lacks distinct form or shape under microscopic exam. May describe oil prone Kerogen.

n: the representation of the magnitude of a variable in the form of a measurable physical quantity that varies smoothly rather than in discrete steps.

n: the rate at which mud is travelling in the annular space of a drilling well.

n: The linear velocity of a fluid passing through an annular space. The term critical annular velocity is often used to describe the flow rate or velocity at which entrained solids will be efficiently transported by the annular fluid. If the fluid velocity f

the velocity of fluids flowing in the annulus. Important in clean-up and displacement processes.

n: an area, usually outlined on a plat attached to a farmout agreement or described in an exhibit, that allows both parties the first right of refusal on leases acquired by either party after the agreement is executed.
