Wettability Evaluation of Arabian Carbonate Reservoir after Prolonged Water Injection: A Case Study

Taha M. Okasha¹

Abstract

Most of the current hydrocarbon production in Saudi Arabia is from Arab-D carbonate reservoir (Upper Jurassic limestone). Oil production started more than 50 years ago. So, the various fields had been subjected to prolonged pressure support by waterfloods (since 1970) using Arabian Gulf sea water.
