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.

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 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.

n: 1. an area of land under exploration that has good possibilities of producing profitable minerals. 2. the set of circumstances, both geologic and economic, that justify drilling a wildcat well. v: to examine the surface and subsurface of an area of land for signs of mineral deposits.

a location where a well is to be drilled.

n: a floating offshore drilling unit that has pontoons and columns that, when flooded. cause the unit to submerge to a predetermined depth. Living quarters, storage space, and so forth are assembled on the deck. Semisutxnersible rigs are self-propelled or towed to a drilling site and anchored or dynamically positioned over the site, or both. In shallow water, some semi-submersibles can be ballasted to rest on the seabed. Semi-submersibles ale more stable than drill ships and ship-shaped barges and are used extensively to drill wildcat wells in rough waters such as the North Sea. Two types of semi-submersible rigs ale the bottle- type and the column-stabilized. See floating offshore drilling rig.

n: a wildcat well.

n: 1. a well drilled in an area where no oil or gas production exists. 2. (nautical) the geared sheave of a windlass used to pull anchor chain. v: to drill wildcat wells.

n: An exploration well. The significance of this type of well to the drilling crew and well planners is that by definition, little if anything about the subsurface geology is known with certainty, especially the pressure regime. This higher degree of uncerta

a well in a previously undrilled area. An exploratory well.
