Company Profile:
A high-pressure, high-volume pump used in hydraulic fracturing treatments.
Industry:Oil & gas
A hole dug to contain brine for disposal by evaporation. Some evaporation pits are lined with plastic or asphalt to keep water from filtering through and contaminating nearby free-water aquifers.
Industry:Oil & gas
A hole or short conduit through which fluids can flow. In equipment applications, a drainhole is generally made to avoid the buildup of pressure within a nonpressure area, such as may occur in the event of a leak in a pressure housing within a tool assembly.
Industry:Oil & gas
A hydraulic fracturing treatment performed in carbonate formations to etch the open faces of induced fractures using a hydrochloric acid treatment. When the treatment is complete and the fracture closes, the etched surface provides a high-conductivity path from the reservoir to the wellbore.
Industry:Oil & gas
A hydrocarbon compound that often precipitates on production components as a result of the changing temperatures and pressures within the production system. Heavy paraffins occur as wax-like substances that may build up on the completion components and may, if severe, restrict production. <br><br>Paraffin is normally found in the tubing close to surface. Nevertheless, it can form at the perforations, or even inside the formation, especially in depleted reservoirs or reservoirs under gas-cycling conditions.
Industry:Oil & gas
A hydrocarbon fluid that is used to dilute heavy oil and reduce its viscosity for easier transportation. Generally a distillation tower cut such as naphtha is used as for heavy oil dilution and transportation. The added diluent may be recovered at the destination using distillation and the diluent may be subsequently pumped back for blending.
Industry:Oil & gas
A high-precision component designed to rupture with the application of a predetermined hydraulic pressure. Rupture disks are commonly used in downhole applications in which the controlled application of pump pressure is used to set or operate downhole equipment, such as packers or plugs. In some applications, a rupture disk may be used as a protection device to prevent overpressurizing a vessel or component.
Industry:Oil & gas
A high-pressure isolation valve fitted to the top of the wellhead on a well that is about to be hydraulically fractured. The frac valve can be closed to isolate the treating equipment from the wellbore.
Industry:Oil & gas
A high-pressure pump designated for well-kill purposes. Depending on the application, the kill pump may need to be connected to a ready supply of kill fluid should well control be required at short notice.
Industry:Oil & gas
A high-pressure pump or compressor unit capable of delivering high-purity nitrogen gas for use in oil or gas wells. Two basic types of unit are commonly available: a nitrogen converter unit that pumps liquid nitrogen at high pressure through a heat exchanger or converter to deliver high-pressure gas at ambient temperature, and a nitrogen generator unit that compresses and separates air to provide a supply of high-pressure nitrogen gas.
