n: The technique used in drilling in order to explore and exploit reservoir. Mainly including wellbore designing, bit choosing, drilling parameter optimization, deviation controling, drilling fluid choosing and drilling hydraulics.

n: a well drilled to confirm and evaluate the presence of hydrocarbons in a reservoir that has been found by a wildcat well.

additional wells drilled after a discovery, to confirm the size of a hydrocarbon deposit. Normally used to run buildup tests, drill stem tests, top and bottom of formation, gather core or fluid samples or other evaluations.

abbr: a trademark name for an annular pressure-responsive valve for a DST string.

annular pressure relief valve. Used in reverse circulating to prevent pipe collapse.

n: 1. a body of coarse, poorly sorted sediments formed by the coalescence of alluvial or detrital fans along the flanks of a mountain range. 2. a similar body of turbidite sediments formed by the coalescence of submarine debris fans along the base of the continental slope.

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.

a geologic formation through which no water flows. It may be an effective seal to the movement of water.

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.
