Tight and complex carbonate reservoirs development requires placing horizontal lateral wells to maximize the reservoir contact across the zones with the best flow potential. Identification of the best permeable intervals and understanding their lateral and vertical continuity are key tasks faced during the field development. It is of critical importance to find means to identify all geological and petrophysical facies changes in such complex rocks. These changes could reveal variations in flowing capabilities of the reservoir. Standard wireline and LWD logs during the appraisal phase do not always provide the necessary information to capture significant facies changes to identify conclusively permeability variations in the reservoir. Fonnation tester logs are expensive and have limitations in tight formations. Incorporating advance analyses of drill cuttings data into petrophysical and geological evaluations significantly improves the capabilities to recognize geological facies variations, even with minor changes in mineral composition, texture and grain sorting. Capturing these variations in the rock are critical to identify permeability and reservoir quality variations. In this paper, a method to integrate drill cuttings analysis into standard formation evaluation program is presented as an alternative to enhance reservoir characterization and description. |
