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.

n: (MODU) a drilling rig that is used exclusively to drill offshore exploration and development wells. It floats on the surface of the water when being moved from one drill site to another. but it mayor may not float once drilling begins. Two basic types of mobile offshore drilling unit are used to drill most offshore wildcat wells: bottom-supported off- shore drilling rigs and floating drilling rigs.

n: the first exploration well in hydrocarbon bearing structure and traping. It also called wildcat well or pioneer well.

n: drilling for oil or gas in an ocean, gulf, or sea, usually on the Outer Continental Shelf. A drilling unit for offshore operations may be a mobile floating vessel with a ship or barge hull, a semi-submersible or submersible base, a self-propelled or towed structure with jacking legs (jack up drilling rig),or a permanent structure used as a production platform when drilling is completed. In general, wildcat wells are drilled from mobile floating vessels or from jackups. while development wells are drilled from platforms or jackups.
