Used in international crude oil trade. Can transport between 160,000 – 320,000 tons of crude oil
Weighted average cost of gas purchased during a given period of time, typically a month
The wash boring method is frequently used in sands and silts to either advance a casing or collect soil samples. Water is pumped down the drill rods under pressure and discharges through ports in the drill bit and carries the soil up to the surface in the annulus between the rod and the boring wall or casing.
The fluid, usually a combination of gas, oil, water, and suspended sediment, that comes out of a reservoir
The ratio of produced water to produced oil
to release pipe that is stuck in the hole by running washover pipe. The washover pipe must have an outside diameter small enough to fit into the borehole but an inside diameter large enough to fit over the outside diameter of the stuck pipe. A rotary shoe, which cuts away the formation, mud, or whatever is sticking the pipe, is made up on the bottom joint of the washover pipe, and the assembly is lowered into the hole. Rotation of the assembly frees the stuck pipe. Several washovers may have to be made if the stuck portion is very long.
A protective structure built around an offshore well to keep boats or floating debris from damaging the wellhead
A well test is when the well is opened up and flowed under controlled conditions. There are several short (hours) periods of flow with various choke valve settings with shut in periods of build up in between. Flow testing confirms the capability of the reservoir to deliver. DST are essential for SEC reserves booking. Testing service to help characterize a reservoir economically and provide as clear a picture as possible of a well’s ability to produce
The right to drill and search for water in the area of a petroleum right and to use the water for drilling and exploration operations
