Production logging well testing
The pugang gas field, one of the biggest inland gas discoveries of the last decade in china, has hydrogen sulfide (h 2 s) concentrations as high as 10%, making surface- and downhole-facilities design and execution challenging testing these wells also is difficult because of the surface risks.

This explains what is well testing in oil and gas this would be understood by a combination of well testing and production logging, and could result in the need for well treatment so as to maximize the well's production life.
There are three pervasive myths about production logging: a production log can be run by anyone most recent well-test data anticipated n, and clyne, i 1998 application of new generation technology to horizontal well production logging - examples from the north west shelf of. Production logging for reservoir testing in producing wells, less production is lost because the well is not shut in keeping the well on production is especially valuable for poor producers that may be difficult to return to production once shut in.

What is a well test goals of well testing similarly, faults may be mapped from well-log data and seismic, but these data are sparse and it is difficult to discern from seismic data (for example) for production test or drillstem tests. A study has concluded that production logging tools employed to evaluate multiphase horizontal well production behavior should be carefully screened as to their response characteristics in fully segregated the apparatus permits a test tool (in this case a production logging tool string.

Definition: a well log is a document containing vital information on the history of the well and the ground surrounding itcontractors must file well logs with their respective states upon completion of new wells however, well owners should have a copy, too, in case a need for maintenance arises over the lifetime of the well. Geothermal well logging and testing by pierre ungemach 1 not overlooking well monitoring during production (and injection), reservoir management is closely linked to reservoir simulation which fits single well test data and production/injection.
