The Challenge Production was declining at a mature oil field where the Bashkirian stage is represented by highly heterogeneous carbonate reservoirs. Severe layering, vertical fracturing, and thin impermeable barriers had
What reservoir conditions are required for PDS to work effectively?What reservoir conditions are required for PDS to work effectively?
Answer: Conventional oil reserves are nearing depletion, and the remaining resources are predominantly found in challenging environments: high temperatures, high‑salinity formation waters, extreme reservoir heterogeneity, and high water cut – often
During a PDS treatment, is there any back‑production of the chemical components to the surface?During a PDS treatment, is there any back‑production of the chemical components to the surface?
Answer: Operators raise this question frequently, and for good reason. With conventional chemical water‑shutoff or EOR treatments, back‑production of unreacted or degraded chemicals is a well‑known operational risk — leading
