- Company Profile:
Oil pumped into a wellbore in preparation for, or as part of, a treatment. Some treatments, such as hydraulic fracturing, involve pumping large volumes of fluid. Using load oil, often produced and processed from adjacent wells in the field, reduces the cost of fluids and can enhance the cleanup process when the treatment is complete.
Industry:Oil & gas
Oil whose free water, sediment and emulsion content (BS&W) is sufficiently low to be acceptable for pipeline shipment.
Industry:Oil & gas
Oil containing small amounts of hydrogen sulfide and carbon dioxide.
Industry:Oil & gas
Oil and dissolved gas volume at reservoir conditions divided by oil volume at standard conditions. Since most measurements of oil and gas production are made at the surface, and since the fluid flow takes place in the formation, volume factors are needed to convert measured surface volumes to reservoir conditions. Oil formation volume factors are almost always greater than 1. 0 because the oil in the formation usually contains dissolved gas that comes out of solution in the wellbore with dropping pressure.
Industry:Oil & gas
Oil containing dissolved gas in solution that may be released from solution at surface conditions. Live oil must be handled and pumped under closely controlled conditions to avoid the risk of explosion or fire.
Industry:Oil & gas
Networks that are described using the mathematics of fractals. These are useful for describing certain types of fracture systems.
Industry:Oil & gas
Nonthermal primary methods of heavy oil production, which include technologies such as production with horizontal wells, multilaterals, CHOPS, water or gas injection.
Industry:Oil & gas
Normally synonymous with a neutron porosity log. However, the term is sometimes broadened to include an activation log.
Industry:Oil & gas
Natural or induced production impairments that can develop in the reservoir, the near-wellbore area, the perforations, the gravel-pack completion or the production pipelines, such as the tubing. Natural damage occurs as produced reservoir fluids move through the reservoir, while induced damage is the result of external operations and fluids in the well, such as drilling, well completion, workover operations or stimulation treatments. Some induced damage triggers natural damage mechanisms. <br><br>Natural damage includes phenomena such as fines migration, clay swelling, scale formation, organic deposition, including paraffins or asphaltenes, and mixed organic and inorganic deposition. Induced damage includes plugging caused by foreign particles in the injected fluid, wettability changes, emulsions, precipitates or sludges caused by acid reactions, bacterial activity and water blocks. <br><br>Wellbore cleanup or matrix stimulation treatments are two different operations that can remove natural or induced damage. Selecting the proper operation depends on the location and nature of the damage.
Industry:Oil & gas
Natural gas, mainly methane and ethane, which has been liquefied at cryogenic temperatures. This process occurs at an extremely low temperature and a pressure near the atmospheric pressure. When a gas pipeline is not available to transport gas to a marketplace, such as in a jungle or certain remote regions offshore, the gas may be chilled and converted to liquefied natural gas (a liquid) to transport and sell it. The term is commonly abbreviated as LNG.
