Wireline logging—specifically wireline formation testing and pressure surveys—provides direct, depth-referenced measurements of in-situ reservoir pressure and fluid gradients, the backbone of ...

Formation testing is the downhole process of measuring in-situ reservoir pressure, estimating permeability/mobility, and capturing representative fluid samples before committing to completion and ...

A cased-hole formation tester proved to be a viable alternative for obtaining reservoir fluid samples and pressure data for characterizing an offshore China oil field. Click here to enlarge image ...

Experience in 1999 during appraisal of the Peng Lai 19-3 field, off China, showed that a cased-hole formation tester has numerous benefits with few drawbacks. This concluding article of a two-part ...
