A reservoir-drive mechanism whereby the oil is driven through the reservoir by an active aquifer. As the reservoir depletes, the water moving in from the aquifer below displaces the oil until the aquifer energy is expended or the well eventually produces too much water to be viable.
Industry:Oil & gas
A reservoir with no apparent outer boundary limit affecting fluid flow during a test period. Unless an outer boundary is close to the wellbore, such as a nearby fault, it usually takes a day or more for outer boundaries to affect well-test results. Since most tests are of relatively short duration, outer boundaries usually do not affect test results.
Industry:Oil & gas
A reservoir maintenance or secondary recovery method that uses injected gas to supplement the pressure in an oil reservoir or field. In most cases, a field will incorporate a planned distribution of gas-injection wells to maintain reservoir pressure and effect an efficient sweep of recoverable liquids.
Industry:Oil & gas
A reproducible inaccuracy of measurement introduced by either faulty design, failing equipment, inadequate calibration, inferior procedure or a change in the measurement environment.
Industry:Oil & gas
A reservoir in which buoyant forces keep hydrocarbons in place below a sealing caprock. Reservoir and fluid characteristics of conventional reservoirs typically permit oil or natural gas to flow readily into wellbores. The term is used to make a distinction from shale and other unconventional reservoirs, in which gas might be distributed throughout the reservoir at the basin scale, and in which buoyant forces or the influence of a water column on the location of hydrocarbons within the reservoir are not significant. <br>
Industry:Oil & gas
A representation, on a plane surface and at an established scale, of the physical features of a part or whole of the Earth's surface or of any desired surface or subsurface data, by means of signs and symbols, and with the means of orientation indicated. Reservoirs are often represented by a series of maps for each of the layers distinguished within the reservoir. This series of maps may include maps of structure, gross thickness, net thickness, porosity, water saturation and other required petrophysical characteristics. A complete set of petrophysical characteristic maps may constitute a reservoir description, reservoir characterization or reservoir model.
Industry:Oil & gas
A rendering of a model of a reservoir or field in entirely numerical formats. Numerical models, once built, may be used to perform many mathematical operations, including calculations of available reserves and simulations of the behavior of the reservoir.
Industry:Oil & gas
A remedial cementing operation designed to force cement into leak paths in wellbore tubulars. The required squeeze pressure is achieved by carefully controlling pump pressure. Squeeze cementing operations may be performed to repair poor primary cement jobs, isolate perforations or repair damaged casing or liner.
Industry:Oil & gas
A relatively small volume of viscous fluid, typically a carrier gel, that is circulated to sweep, or remove, debris or residual fluids from the circulation system.
Industry:Oil & gas
A relatively short, heavy-walled completion component installed in areas where turbulence is anticipated. The additional wall thickness prevents early failures due to erosion in the turbulent flow area. Flow couplings are typically installed above and below completion components, such as landing nipples, that may affect the flow.
