A fallout test measures the pressure decline subsequent to the closure of an injection. It’s conceptually identical to a buildup test. As with injection tests, falloff test interpretation is more difficult if the injected fluid is different from the original… Read More ›
Used to measure the flowing bottom-hole pressure of a reservoir to determine its productivity index, the flowing gradient of the well fluids, possible communication between zones, and to investigate the efficiency of the gas-lift valves. The pressure survey is carried… Read More ›
Well acidizing is a form of well stimulation done to increase or restore well production level.
Well fracturing is a production simulation technique performed above the reservoir (formation) pressure which causes fracturing and causing a highly conductive flow path between the reservoir and the wellbore. Performed when the well have been completed or after the casing,… Read More ›
Oil production stage typically separated into three phases: Primary: Primary oil recovery is limited to hydrocarbons that naturally rise to the surface, or those that use artificial lift devices, such as pump jacks: Secondary recovery employs water and gas injection,… Read More ›
Water injection, also known as waterflood, is a form of this secondary EOR production process.
Used on offshore oil and gas fields, a subsea tree monitors and controls the production of a subsea well. Fixed to the wellhead of a completed well, subsea trees can also manage fluids or gas injected into the well
One theory is that “pig” stands for Pipeline Intervention Gadget.
Another theory states that a leather-bound pig was being sent through the pipeline, and while it passed, the leather squeaked against the sides of the pipe, sounding like a squealing pig
3 main ways that subsea pipe is lay using a pipelay vessel. S-lay J-lay Tow-in The Buoyancy Affect It’s both positive and negative [Positive] In the water, the pipe weighs less if it is filled with air, which puts less… Read More ›
Originally conceived as a bottom-supported drilling unit.
