The useful application of radial flow models is obviously dependent on making a reasonable estimate (assumption) of the extent of the region around a given well over the which the flow is radially symmetric.
Basic Well Completion Design (Wellhead & Christmas Tree) Well Completion Accessories (Typical accessories) Tubing hanger To provide a seal between tubing & wellhead To support tubing Flow coupling To protect from internal erosion caused by high velocity & turbulence flow… Read More ›
Well tests conducted at a series of different flow rates for the purpose of determining well deliverability, typically in gas wells where non-Darcy flow near the well results in a rate-dependent skin effect. Multiple-rate tests are sometimes required by regulatory bodies.
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 ›
Also refereed to as drill mud, are added to the wellbore to facilitate the drilling process by suspending cuttings, controlling pressure, stabilizing exposed rock, providing buoyancy, and cooling and lubricating.
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
Drillship were 1st developed in the 1940s by marine architects to overcome water depth challenges offshore California in the Pacific Ocean. The 1st drillship was a surplus U.S. Navy patrol craft that was equipped with cantilevered drilling equipment. Seeing some… Read More ›
