v: The sucking way that drill fluid be sucked in pump by atmospheric pressure.
abbr: unconformity;used in drilling reports.
n: 1. lack of continuity in deposition between rock strata in contact with one another, corresponding to a gap in the stratigraphic record. 2. the surface of contact between rock beds in which there is a discontinuity in the ages of the rocks. See angular unconformity, disconformity.
n: A geological surface separating older from younger rocks and representing a gap in the geologic record. Such a surface might result from a hiatus in deposition of sediments, possibly in combination with erosion, or deformation such as faulting.
a geologic aged erosional removal from the top of a formation. Reservoir rocks below this surface may contain hydrocarbon deposits if the unconformity acts as a seal.
n: a loosely arranged, apparently unstratified section of rock.
n: The formation that containing lesser cementing material,and havent well solidated between mineral grains.
formations with insufficient cementing agents between the grains to stop movement of individual grains when fluid flows through the formation. Usually less than 2 to 10 psi compressive strength.

n: A kind of sand that have negligible cohesive force between grains ,which have bad cementation.
n: a sand formation in which individual grains do not adhere to one another. If an unconsolidated sand- stone produces oil or gas, it will produce sand as well if not controlled or corrected.
n: It has bad bonding strength , and falling scattered readily ,because of lacking of cemetation between grains.
n: The formation that havent be damaged by drill fluid ,slurry and perforating fluid.
n: The formation that havent be damaged by drill fluid ,slurry and perforating fluid.

n: The drilling that the amount of pressure (or force per unit area) exerted on a formation exposed in a wellbore below the internal fluid pressure of that formation.Its advantage is have quick rate of drilling,and finding oil and gas formation readily,but h
