THERMAL ENHANCED OIL RECOVERY
HIGH-TEMPERATURE ADDITIVES FOR THERMAL EOR
Thermal Enhanced Oil Recovery (EOR), particularly steam processes, suffer from conformance and mobility control. In addition, the condensed water is not a good solvent for oil and therefore does fully recover the oil trapped in tighter and smaller pores.
Dow is developing solutions to combat both problems – ELEVATE™ Steam Foam Additives to control conformance issues in steam floods and hot spots in SAGD, as well as ELEVATE SAGD Steam Oil Ratio (SOR) Improvement Additives to improve the efficiency of SAGD operations. ELEVATE Additives are focused on increasing the oil production rate, increased total oil recovery over time and decreasing steam to oil ratios.
Combined with Dow’s implementation expertise, backed by decades of experience in additives for use in oil production, these products will help recover more oil while significantly reducing water and energy use.
ELEVATE™ Steam Foam Additives
Non-heterogeneous reservoirs cause flow segregation whether in SAGD, steam drive or CSS. Dow’s conformance control additives generate in-situ foam to minimize challenges in steam floods and hot spots in SAGD.
ELEVATE™ SAGD SOR Improvement Additives
The efficiency of SAGD production is measured by the steam to oil ratio (SOR). Dow has developed testing capabilities and a product line of additives to improve the oil production rate and total oil recovery over time and decrease the steam to oil ratios. These volatile surface active materials work to improve drainage resulting in reduced SOR.
