Worm-like micelles as a mobility control agent for chemical enhanced oil recovery
In this Paper, Wormlike Micellar (WLM) solutions were studied as an alternative to polymeric mobility control agent in chemical enhanced oil recovery. In which, two compositions of WLM solutions were chosen and prepared in laboratory - Hexadecyltrimethylammonium Bromide/Sodium Nitrate and Three-(N,...

In this Paper, Wormlike Micellar (WLM) solutions were studied as an alternative to polymeric mobility control agent in chemical enhanced oil recovery.

Then following experiments were conducted - thermal stability test, rheological measurements to account the effects of concentration, shears rates, salinity (NaCl = 3.5 w/v, CaCl2 = 0.05 w/v and MgCl2 = 0.05 w/v), and temperature (30 to 70°C) on viscosity of these WLM solutions. Another stability test was conducted to test the effect of crude oil on WLM solution. The results showed that WLM solutions have excellent rheological resemblances with HPAM polymer solutions. On addition of salts, the WLM solutions were highly tolerant over entire range of shear rates. At 70°C, the thermal degradability of WLM solutions was less than HPAM polymer. Despite of all these significances viscosity of WLM solutions was deemed to the viscosity of water (1 cP) on mixing crude oil.
