Abstract

This paper examines some of the challenges related to the application of alkali-surfactant-polymer (ASP) flooding in hightemperature<br>carbonate oil reservoirs. In particular, the calcium sulfate minerals gypsum (CaSO4.2H2O) and anhydrite (CaSO4)<br>often present in small quantities in carbonate formations, have long been recognized as obstacles to chemical flooding. We<br>illustrate these challenges for an 83 ºC carbonate field, initially containing evaporitic water, flooded with an ASP slug mixed<br>in seawater, and followed with a polymer drive in diluted seawater.
