the stresses on the formation imposed by the overlying overburden and tectonic forces. The stresses are at least partially offset by the fluids in the pores of the formation.

n: the trade name of an intrument used to determine whether or not the well bore is proceeding in a vertical orientation at any point. In most drilling operations, either regulations of government bodies or contract stipulations,or both, provide a maximum de

n: (IPAA) an organisation of independent oil and gas producers concerned with the relationships between the oil industry and the public and government. Its official publication is Petroleum Independent. Address: 1101 16th Street NW, 2nd FL.;Washington, DC 20036;(202) 857-4722.

n: drilling wells between known producing wells to exploit the re- sources of a field to best advantage.

n: the drilling for improving the output and progressing rapaidly among the oil fileds.

adding new wells in an existing field within the original well patterns to accelerate recovery or to test recovery methods.

n: a well drilled between known producing wells to exploit the reservoir better.

n: the hore that added to the original recovery well just for exploring rapaidly.

n: a packer with an element that inflates by means of gas or liquid pumped from the surface through a line. It is deflated by means of slots that can be opened to allow the gas or liquid to flow out They are used when a temporary packer is needed in a hole with weakened casing that could be damaged by mechanical slips.

n: A type of packer that uses an inflatable bladder to expand the packer element against the casing or wellbore. In preparation for setting the packer, a drop ball or series of tubing movements are generally required, with the hydraulic pressure required to

a device with metal slats or cords woven around a rubber bladder with an elastomer cover designed to inflate in the wellbore and provide isolation.

n: overload or short-circuit protection built into the motor windings.

n: one kinds of open hole completion , that is putting the casing to the bottom of oil layer and then drilling recovery layer.

n: the early production of an oilwell, recorded after testing operations and recovery of load oil and used as an indicator of the maximum ability of a well to produce on completion without subsequent reservoir damage.

flow rate, often from a short test, measured during a test at or just before completion.

the pore pressure in a reservoir at the time of discovery.
