English Abstract
Two exploration wells were selected near Mosul city (Ain Zala-29, Jabal Kand- 1) and one outcrop section in Kani Masi- Zakho, near Sararo village in Iraqi Kurdistan Region.
This study performed into two phases, study palynofacies and hydrocarbon generation potential of the Middle Triassic Geli Khana Formation. Fifty one slides are prepared in this study for the assessment of palynofacies types.
Three palynofacies were tentatively recognized, The first palynofacies (P.F.1) is diagnostic of the Geli Khana Formation in the outcrop Ora section from distance 1-43 m and well Jabal Kand-1 from drilling depth 4900 to 4697 and 4532 to 4369m; the second palynofacies (P.F.2) also appeared in Ora section from 44-280 m and in well Jabal Kand-1 from drilling depth 4697 to 4532m, while palynofacies three (P.F.3) is found in both wells, in Jabal Kand-1 from drilling depth 4369-4112 m but in Ain Zala -29 from drilling depth 4900-4650m, and in Ora section from 280-499m.
They were distal suboxic–anoxic basin, to distal dysoxic–anoxic shelf, shelf to basin transition Passage from shelf to basin in time.
X-ray diffraction technique, showed that the ratio of clay mineral (illite) increase upward of the Geli Khana Formation (illite increase basin ward) that could confirm the environmental aspect. Pyrolysis analyses showed that the organic matter type in well Jabal Kand-1 is mostly types II-III, and III, while in both outcrop and well Ain Zala-29 it is type IV.
Total Organic Carbon (TOC) ranged between 0.27-1.41 in well Jabal Kand- 1, 0.27-0.41 in well Ain Zala-29- and very low TOC in outcrop.
In both Jabal Kand-1 and the outcrop vitrinite reflectance (R0%) is more than 1.4, Thermal alteration index (TAI) 3.3-3.7 and 4, and low fluorescence intensity are indicators for mature stage (dry gas window), for all the studied samples, and hence mainly gas generation could have been performed from Geli Khana Formation in mainly Jabal Kand locality.
