| 520 | |b The Ketatna Formation (Dirbal Formation) of Oligocene to Early Miocene age is composed of mainly carbonate sequences which are present in the subsurface of north-west Libya, offshore. The type section is represented by well A1-NC41 drilled by Agip Oil Company. The lithology of The Ketatna Formation can be subdivided into two main units, an upper wackestone- packstone unit and a lower grainstone- boundstone unit. The lower unit of Ketatna Formation consists of mainly, grainstone-boundstone. The upper units consist mainly of alternating white-greyish wackestones and packstones. Locally Ketatna Formation consists of reefal facies characterized by abundance of dissolution cavities. Ketatna Formation base is composed of nummulites beds unconformably overlain by Al Mayah Formation and overlies Tellil Group unconformably. The purpose of this paper is to evaluate the Ketatna Formation reservoir for future drilling into Metlaoui main reservoir in the area of offshore Libya. Wells A1, A2, J1-NC41, K1, B1a-137, K1, D1a and J1 drilled in the offshore area encountered three major sequences facies separated by major unconformities. It represents three major phases of reactivated paleohighs probably initiated during Triassic time. The unconformities associated with possible tectonic pulses causing the sea level to drop as represented by the Formation of Ketatna and evidenced by three facies of marl shale locally silty, deposited in a distal environment of Salammbo Formation. The fine to coarse grained packstone is composed of skeletal debris of Echinodermata, Hydrozoa, Algae facies, and benthonic foraminifera probably deposited on the build-up flanks of fore-reef-slope facies of Ketatna Formation. These three main facies represent dolomitic shale interbedded with skeletal pack-Grainstone probably deposited in a shallow internal lagoon. The Boundstone- grainstone composed of Hydrozoa and other frame-build-up and Packstone- Grainstone containing skeletal fragments coated by micrite rims, Crinoidea, Ostracoda, Algae, interaclasts with pellets of subordinated hydrozoa and molluscs fragments, is interpreted as possible back-reef facies. | ||
