Sequence Stratigraphic Framework of the Arab Formation Reservoirs, Dukhan Field, Qatar

In the Upper Jurassic Arab C and D reservoirs, three 3rd-order sequences are interpreted in Dukhan Field, Qatar and are<br>refered to as the Kim1, Kim2, and Kim3 sequences (after Hardenbol et al., 1998). At Dukhan, the Arab C and D reservoirs<br>have produced since 1949. Over 800 wells have been drilled in Dukhan, 180 of which have been cored. Based on<br>sedimentological analysis of the cores, environments of deposition (EODs) have been assigned to cored wells. Twenty three<br>EODs were identified and grouped into five facies tracts: Sabkha, Beach, Ramp Interior, Ramp Crest, and Outer Mid Ramp.<br>Parasequences and parasequence sets were recognized in the core data, and sequences were interpreted from the<br>parasequence stacking patterns as well as evidence for exposure. Log-based correlation provides a method for extending the<br>sequence stratigraphic framework from cored to uncored wells across the field.
