What is oil well logging?

Oil well logging, also known as borehole logging, is a process where specialized instrumentation is inserted into a borehole to determine the properties of the geological formations surrounding the bore.

What is well testing in oil and gas?

In the petroleum industry, a well test is the execution of a set of planned data acquisition activities. The acquired data is analyzed to broaden the knowledge and increase the understanding of the hydrocarbon properties therein and characteristics of the underground reservoir where the hydrocarbons are trapped.

How do you find well logs?

Depending on your location, your state or county health department, Department of Natural Resources, or some other similar agency may house well logs that you can access or request a log from. If you know who drilled your well, it might be a good first step to contact them and ask for your log.

What is logging in oil and gas?

Well logging, as it applies to the petroleum industry, is used to identify oil and gas intervals, and quantify properties of reservoir rock by placing various types of sensors in the borehole. The signatures are then analyzed to evaluate the formation properties that are of interest for producing oil and gas.

What are the methods used for well test analysis?

The chapter explains six interpretation methods for well tests: (1) wellbore storage and skin effect, (2) outer boundaries and discontinuities, (3) well-test interpretation, (4) pressure-derivative analysis, (5) interpretation using simultaneously measured pressure and sand-face flow rate, and (6) wellbore storage …
