Considering the importance of petro physical analysis and integrated advanced applications of electrical logs and techniques that may give way to a more in-depth investigation of the possibility of accumulation of Hydrocarbon with commercial quantities after appraisal and development schemes of well drilling operations, and in light of this principle, this paper dealt with the study of Tahara Fm. sand (Wafa Field, NC169a Block, South Western Libya) considering the formation as a secondary target for production of Oil and focus on key issues link to adopt more investigation and intense the potential toward this task. Tahara Fm. (Middle Devonian age) Consists of sand layer (divided into upper and lower units) interbedded with little Shale layers, with Gross Thickness ranges from 142 to 180 feet. Five wells from Wafa Field (A2, A3, A34, A36 & A45 NC169a) were selected for this study (Fig.3). Those wells were drilled targeting the production of Hydrocarbon from Aouinet Ouenine F3 Sand Fm. and cut the Tahara Sand (formation of interest) deploying some Wire line logs and planning for cutting a sidewall cores for this bed in future. Logging data were analyzed in terms of petro physical characteristics of the sand using Tech Log software 2015, and the reserve was estimated upon the analysis results. The upper unit of Tahara sand has fair to good quality reservoir than lower unit, where the total porosity in upper unit is about 12%, the net pay thickness is about 17 feet and water saturation in upper sand reaches 34%. Reserve estimation results showed 6940711.768 MMSTB (Oil in Place) and oil recovery of about 2024374.266 MMSTB. |
