A secondary recovery production system that utilizes steam injection to reduce the viscosity of highly viscous oil, enabling viable production rates.
Industry:Oil & gas
A section of heavy walled tubing that is placed across any perforated interval through which the production tubing must pass, such as may be required in multiple zone completions. In addition to being heavier than normal completion components, the wall of a blast joint is often treated to resist the jetting action that may result in the proximity of the perforations.
Industry:Oil & gas
A sea vessel used to transport liquefied petroleum gas (LPG). The term is commonly abbreviated as LNGC
Industry:Oil & gas
A sand-control method used to prevent production of formation sand. In gravel pack operations, a steel screen is placed in the wellbore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation sand. The primary objective is to stabilize the formation while causing minimal impairment to well productivity.
Industry:Oil & gas
A schematic diagram that identifies the main completion components installed in a wellbore. The information included in the wellbore diagram relates to the principal dimensions of the components and the depth at which the components are located. A current wellbore diagram should be available for any well intervention operation to enable engineers and equipment operators to select the most appropriate equipment and prepare operating procedures that are compatible with any downhole restrictions.
Industry:Oil & gas
A sample of liquid or sediments obtained at a specific depth inside a tank using a thief or a bottle. Spot samples are analyzed to determine the gravity of the oil and BS&W content of the fluid in the tank.
Industry:Oil & gas
A sand body that contains heavy hydrocarbon residues such as tar or asphalt, or degraded oil that has lost its volatile components. Hydrocarbons can be liberated from tar sands by heating and other processes, but tar sands, such as the Athabasca tar sands of Canada, are not commonly commercial because of high costs of production. <br><br>Among some workers in the field of heavy oil, this term is falling out of use, in favor of the term "oil sand. "
Industry:Oil & gas
A safety device attached to the slickline at surface between the hay pulley and stuffing-box pulley. The wire clamp generally is applied when the slickline is to be stationary for a period of time. This prevents the tool string from dropping down the wellbore if the winch unit fails or the slickline becomes damaged at surface.
Industry:Oil & gas
A safety device installed in the upper wellbore to provide emergency closure of the producing conduits in the event of an emergency. Two types of subsurface safety valve are available: surface-controlled and subsurface controlled. In each case, the safety-valve system is designed to be fail-safe, so that the wellbore is isolated in the event of any system failure or damage to the surface production-control facilities.
Industry:Oil & gas
A safety device used when running and retrieving tools or drill collars with a flush external surface that may easily pass through the rotary table slips. The dog collar is temporarily attached to the assembly between the tool joint and the slips. If the slips fail to hold the tool assembly, the dog collar will prevent the entire assembly from dropping through and being lost in the wellbore.
