How pre-conditioning the reservoir before large-scale injection permanently changed the economics of Field A. Client: Client BField: Field ATechnology: Polymer-Disperse Systems (PDS)Innovation Focus: A proactive paradigm shift from remedial “fix” to preventive “design” in
Answer: PDS EOR was historically developed for — and achieved its first large‑scale success in — late‑stage, mature fields suffering from the classic symptoms of advanced waterflooding: high water cut (often exceeding
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
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
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
Answer:Polymer-Dispersed Systems (PDS) serve two distinct but complementary missions — deep-acting EOR conformance and near-wellbore water shutoff — using the same tunable chemistry. The fundamental operational difference is the well type, the scale of impact, and
Answer: PDS is not inherently “better” in one lithology. It is a purpose‑engineered conformance technology whose performance is shaped by the reservoir’s void‑space architecture. Its decisive advantage is the ability
Answer: Polymer‑Dispersed System (PDS) is an advanced two‑component conformance control technology designed to achieve true sweep correction in heterogeneous and mature oil reservoirs. Unlike conventional polymer flooding or bulk gel treatments, PDS does not simply
Executive Summary This case study examines the application of a tailored Polymer Dispersed System (PDS) in a mature oil field characterized by extreme vertical heterogeneity and high formation water salinity
Technical Case Study – Laboratory Breakthrough 1. The HTHS Carbonate Challenge: Why Conventional Solutions Fail Carbonate reservoirs hold approximately 60% of the world’s remaining conventional oil reserves, yet they present
