Static review and STOIIP estimate
In 2018, TRACS conducted a static review for the Elon field. The review covered the petrophysical, logderived facies and seismic geobody interpretations. Electrofacies from logs were generated and facies proportions by well extracted. Improvements pertaining to facies proportions in the provided model have been suggested to Tullow and these are being implemented into all fields in the Ceiba-Okume area. GRVs found in the static model provided by Tullow have been adopted. Results from the detailed analysis of the Elon field in analogue reservoirs have been used to determine appropriate N/G, porosity and oil saturation levels pertaining to each facies class. N/G associated with thin sand layers (<2 cm) as proven by producing wells has been added. Porosity and saturation are not considered key uncertainties and thus probabilistic variations have been kept small. Based on the review the TRACS in-place volumes are higher than Tullow’s: TRACS’ 517-750-1045 MMstb (P90, P50, P10) versus Tullow’s 453-615-800 MMstb. For the assessment of recovery factors for this review the TRACS figures have been used.
