To reduce pressure in a wellbore by moving pipe, wireline tools or rubber-cupped seals up the wellbore. If the pressure is reduced sufficiently, reservoir fluids may flow into the wellbore and towards the surface. Swabbing is generally considered harmful in drilling operations, because it can lead to kicks and wellbore stability problems. In production operations, …
In transporting gas from the production field to the end user, the demand fluctuates throughout the day, known as “diurnal swing”. The production field exports gas at a steady rate, but it is used variably throughout the day by customers (e.g. less during the night). Some of this swing capacity can be built into the …
Basin – or trough-shaped fold in rock in which rock layers are downwardly convex. The youngest rock layers form the core of the fold and outward from the core progressively older rocks occur. Synclines typically do not trap hydrocarbons because fluids tend to leak up the limbs of the fold. Opposite of anticline
Hot water is used to extract (or separate) the bitumen from the oil sand. It is then upgraded to produce “synthetic’ crude oil and other petroleum products. This is done by removing carbon and adding hydrogen to remove impurities such as nitrogen and sulfur. The upgraded product is called “synthetic” because it is altered from …
A floating device used in offshore seismic surveys to identify the end of a streamer. Tail buoys allow the seismic acquisition crew to monitor the location and direction of streamers. They are commonly brightly colored, reflect radar signals and are fitted with Global Positioning System (GPS) receivers.
The support form of an offshore installation on which the derrick, engines, quarters, helicopter pad, cranes, etc., are installed

Natural gas that contains no sulfur or sulfur compounds at all or in such small quantities that no processing is necessary for their removal in order that the gas may be used as a non-corrosive fuel. One of the most important parts of gas processing involves the removal of sulfur and carbon dioxide. Because of …
Synchronization of the Facility tests to assure the synchronization capability of any power station are part of a power station’s Acceptance Tests, when a qualified tester working on behalf of the holder of a transmission license or the holder of a distribution license, as applicable, confirms that the facility meets all the conditions for feeding …
Parties in a gas sales agreement (GSA) agree a minimum quantity of gas to be purchased for each year, the Take or Pay amount. If the buyer takes less than this amount, he will pay for the balance not taken. To arrive at the ToP amount: x% of the ACQ less underdeliveries by the seller; …
