WebMethods of using pressure build-up or flow tests to estimate formation permeability, formation pressure and well damage are reviewed. A number of phenomena which cause actual pressure build-up behavior to differ from the idealized case, such as the effects of boundaries, skins, inhomogeneities, partial penetration and two-phase flow, are discussed. WebOct 27, 2016 · Well Testing & Well Test Analysis 3.3- Draw-Down Test (DD): A well is flown at a constant rate and the pressure change (decline) is monitored Derived Parameters: k, s, d 3.4- Build-Up Test (BU): A …
WebJan 16, 2014 · After flowing a well over a stable period via a flow meter (test separator meter, orifice place, MPFM…), shutting-in the well with a surface or downhole valve for a finite time interval defines a well test. For a producer, pressure at the well builds up during a test: This is called a Pressure Build-Up (PBU) test. WebBuild-up test: the increase of bottom hole pressure after shut-in is used for analysis. Before the build-up test, the well must have been flowing long enough to reach stabilized rate. During shut-in periods, the flow rate is accurately controlled (zero). It is for this reason build up tests should be performed.

WebMar 23, 2015 · BUILD-UP A build-up test requires the reservoir to be flowed to cause a drawdown then the well is closed in to allow the pressure to increase back to, or near to, the original pressure which is termed the pressure build-up or PBU. This is the normal type of test conducted on an oil well and can be analysed using the classic Horner Plot or ... aussama nassarWebIt is common to see some simple analysis when interpreting a well test or a pressure build-up test.
