annular pressure relief valve.

acceptance quality level.

a relatively impermeable stratum that does not transmit water fast enough to supply a well.

n: 1. a permeable body of rock capable of yielding groundwater to wells and springs. 2. the part of a water drive reservoir that contains the water.

n: (1) water bearing strata. (2) aqueous section in water controlled reservoir.

a water containing formation that may or may not be directly connected to the hydrocarbon bearing zone. A connected aquifer may or may not offer pressure support to the pay.

abbr: circulated;used in drilling reports. circle wrench n: see wheel-type back-off wrench.

n: This method assumes the borehole axis in adjacent measurement station is arc which located in oblique plane. It is a kind of well path computational method.

v: to join metals by utilising the arc created between the welding rod, which serves as an electrode, and a metal object. The arc is a discharge of electric current across an air gap. The high temperature generated by the arc melts both the electrode and the metal, which fuse.

a large, load supporting formation that may serve to reduce the total overburden load on a pay zone. These formations may cover hundreds of square miles over a basin. A second use is as a semi-stable structure of sand grains around a perforation or other

Empirical relationships between the formatu=ion resistivity factor, the porosity, water saturation and the restivity of the fluid in the pore in clean, granular rock.
