multiple-rate tests

Oil & gas; Oilfield

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 ...

deliverability test

Oil & gas; Oilfield

Tests in an oil or gas well to determine its flow capacity at specific conditions of reservoir and flowing pressures. The absolute open flow potential (AOFP) can be obtained from these tests, and ...

pumping well tests

Oil & gas; Oilfield

Testing that is accomplished by measuring pressure in the annulus, or by pulling the pump and running a pressure gauge in the hole. The preferred method is usually to measure the pressure in the ...

wireline formation test

Oil & gas; Oilfield

Test taken with a wireline formation tester. The wireline formation pressure measurement is acquired by inserting a probe into the borehole wall and performing a minidrawdown and buildup by ...

Techniques that use equations or algorithms that have been previously developed for similar situations. These methods do not involve stochastic or statistical approaches. Deterministic methods are ...

quartile

Oil & gas; Oilfield

Special quantiles at 0%, 25%, 50%, 75% and 100%.

geostatistical methods

Oil & gas; Oilfield

Techniques that are applied to reservoir characterization using various statistical approaches to estimate the geological characteristics of formations at a distance from known points, such as within ...
