A surface detection technique to verify that perforating guns have fired. This technique typically employs sensors that detect vibration or hydraulic shock at surface, and is used with TCP operations.
Industry:Oil & gas
A surface detection system used to ensure that all tubing-conveyed perforating guns have fired, from the top shot to the bottom shot.
Industry:Oil & gas
A support structure used to stabilize the injector head and pressure-control equipment on some offshore, or special onshore, coiled tubing units. The jacking frame is hydraulically controlled to enable the injector head to be located at a safe and secure working height. Additional features, such as the ability to skid the injector head to the side for access to the wellbore are included in some of the more complex designs of jacking frame.
Industry:Oil & gas
A supporting ring used with an O-ring, or similar seal, to prevent extrusion of the seal material under high differential pressures or excess wear under dynamic sealing conditions.
Industry:Oil & gas
A supertanker with a capacity between 100,000 and 500,000 deadweight tons. The term is commonly abbreviated as VLCC.
Industry:Oil & gas
A sufficiently dry gas that will not drop out natural gas liquids (NGL) when entering the gas pipeline; also, gas with enough pressure to enter high-pressure gas pipelines.
Industry:Oil & gas
A supertanker with 500,000 deadweight tons of capacity or more. The term is commonly abbreviated as ULCC.
Industry:Oil & gas
A succession of strata deposited during a single cycle of deposition. These sedimentary successions usually occur repeatedly, one above the other. The two main varieties are the cyclic units that are symmetrical cyclothems, and the rhythmic units that are asymmetrical cyclothems. Cyclic groupings of cyclothems are called megacyclothems, and cyclic groupings of megacyclothems are called hypercyclothems. Cyclothems are thought to be due to natural cycles, such as changes in sea levels related to changes in the volume of polar ice caps.
Industry:Oil & gas
A succession of genetically related parasequences that form a distinctive stacking pattern, and that are typically bounded by major marine flooding surfaces and their correlative surfaces. Parasequence sets are usually classified as progradational, aggradational or retrogradational.
Industry:Oil & gas
A substance used in a gas-dehydration unit to remove water and moisture. The desiccant can be liquid, such as methanol, glycol (ethylene, diethylene, triethylene, and tetraethylene). Dessicants also can be solid, such as silica gel or calcium chloride (CaCl<sub>2</sub>). <br><br>The most common gas-dehydration system (glycol dehydrator) uses liquid desiccants such as diethylene, triethylene and tetraethylene, which are substances that can be regenerated. Regeneration means that the water absorbed by these substances can be separated from them. Some liquid desiccants such as methanol or ethylene cannot be regenerated. <br><br>Solid desiccants are also used for gas dehydration. They are placed as beds through which wet gas is passed. The main limitation of the use of solid dessicants is that they absorb only limited quantities of water. When the desiccant saturation point is reached, the solid dessicant must be replaced. Another limitation is that sometimes water cannot be removed from it.
