Performance Evaluation of STARPAM Polymer and Application in High Temperature and Salinity Reservoir

Table 9

Comparison of oil displacement effect.

K / 10^−3μm^2	Sample	μ; / mPa·s	/ %	/ %	Polymer flooding
					1500 mg/L, 0.2PV
					/ %	/ %
1050	STARPAM	45.1	67.64	40.77	61.30	20.53
1039	MO-4000	14.5	66.67	40.37	57.50	17.13
1145	HPAM	11.3	66.79	40.31	52.40	12.09

Remarks: K: permeability, μ: viscosity, : oil saturation, : recovery of water flooding, : cumulative recovery, and : enhanced oil recovery of polymer flooding.
