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

Is PDS only an EOR technology, or can it also be used for water shutoff? How does the application differ for each objective?Is PDS only an EOR technology, or can it also be used for water shutoff? How does the application differ for each objective?
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
Where does PDS deliver its highest efficiency – in sandstones or carbonates – and what drives the difference?Where does PDS deliver its highest efficiency – in sandstones or carbonates – and what drives the difference?
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
What is Polymer‑Dispersed System (PDS) technology and how does it differ from traditional methods?What is Polymer‑Dispersed System (PDS) technology and how does it differ from traditional methods?
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
