Abstract
Improved oil production is critical today when some analysts are predicting world oil production is peaked. Conformance control using PPG and surfactants and is one of the effective ways to prolong reservoir’s lifetime by increasing sweeping efficiency and mitigate issues like excess water production in heterogeneous reservoirs. But, there are huge uncertainties concerning the in-situ gelling properties in the industry. This paper will discuss how surfactant and PPG properties ( types, concentration, size) affect the two important gelling parameters: swelling ratio and dynamic shear modulus, G’. The PPG behavior has been investigated extensively in the lab, showing that (1) surfactant can increase the swelling capacity of the PPG up to 7.5 % rise compared to its swelling capacity in 10.0 wt % brine however high surfactant concentration will decrease the swelling capacity; (2) All surfactants reduced the PPG G’ significantly. Largest reduction occurs in anionic and cationic surfactant.
