v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

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.

n: The reconnoiting drilling into the undrilled zone below 4000m.

v: to drill a hole until basement rock is encountered, usually in a wildcat well. If no hydrocarbon-bearing fonnations are found above the basement, the well is assumed to be dry. The term comes from the fact that basement rock is sometimes granite.

n: a method of exploration drilling in which drills to the basement when drills the wildcat well

n: a lease or a number of leases of adjoining tracts of land that constitute a unit of acreage sufficient to justify the expense of drilling a wildcat.

n: the lease used for oil finding in early drilling

n: the search for reservoirs of oil and gas, including aerial and geophysical surveys, geological studies, core testing, and drilling of wildcats.

a general term covering the search for oil and gas.

n: a well drilled either in search of an as-yet-undiscovered pool of oil or gas (a wildcat well) or to extend greatly the limits of a known pool. It involves a relatively high degree of risk. Exploratory wells may be classified as (1) wildcat, drilled in an unproven area;(2) field extension or step-out, drilled in an unproven area to extend the proved limits of a field;or (3) deep test, drilled within a field area but to unproven deeper zones.

n: A well drilled in an unproven area where no oil and gas production exists (sometimes called a wildcat).

a wildcat or well in a new area with unknown producing potential.

abbr: local distribution company. leaching n: in geology, the removal of minerals from rock by solution in water or another solvent.

long distance carrier.

n: (LDC) a company that sells natural gas to homes, offices, and businesses in towns, cities, or relatively small rural areas.
