Production and injection profiling through permanent downhole pressure gauge, a novel and unique application, has been proposed in the present paper. Theoretical development of the new technique is first provided. Example studies are then given to illustrate the application of the technique. Application scenarios, practical issues as well as key impacting parameters have also been addressed. Finally, a field case study implementing the new technique for a long horizontal well has been performed to demonstrate how the production profiles calculated from PDG data compare to the results from a recent PLT survey which turns out to be expensive yet unsatisfactory. The technique could be applied to real-time production and injection profiling for different well configurations (vertical, horizontal, deviated and multilateral) and bring tremendous financial benefits through replacing conventional production logging surveys that could be cost-extensive for horizontal or multilateral wells offshore.
