OPC has provided PTA support for our clients during their clean up phases of newly drilled development wells.
The cleanup phase can be a great source of dynamic production data as each well is tested individually one by one while the reservoir is in virgin conditions. These tests can give great insights into nearby geometry effects without the influence of offset producing wells.
In collaboration with our client, OPC PTA experts optimised the test design for each cleanup and performed real-time interpretation, taking advantage of unplanned pressure build-ups (PBUs). This meant OPC could deconvolve and interpret the entire test in real-time and thus cut short the final PBU as test objectives had already been met. Ultimately, this has saved our client rig time and thus associated costs.
After the first gas, OPC will continue the PTA interpretation and hope to perform advanced pressure rate deconvolution techniques to determine dynamic volumes connected to the well stock.
