Bottomhole Pressure Test
Definition - What does Bottomhole Pressure Test mean?
Bottomhole Pressure Test is a test that is done to determine the reservoir pressure of a wellbore. The results can be acquired at a certain level or at a specific depth of the producing zone. There are two main categories of the test, i.e., flowing Bottomhole Pressure Test and Shut-in Bottomhole Pressure Test. When the test is measured during the flowing well, it is known as Flowing Bottomhole Pressure Test whereas if the well is shut for a specific period of time then the test done, it is said to be a Shut-in Bottomhole Pressure Test.
Petropedia explains Bottomhole Pressure Test
The Bottomhole Pressure can be determined by various methods. The methods basically involve the measurement of flow rate variation with time. The tests are economical and they extract some valuable information about the characteristics of the well and the reservoir. The major parameters to obtain data regarding the skin are wellbore storage constant, productivity index and static gradients. A Bottomhole Pressure Test fetches information about reservoir surveillance, gas lift optimization, material balance calculation and reservoir simulation. For more concrete results, the test is divided into different categories such as injectivity test, pulse test and build-up test.
