Abstract
The Miocene reservoir of the “Horse” Field comprises sands, silts and muds, attributed to deposition from short-headed turbidite fan. The reservoir ranges in thickness from 30.5 m to 122.0 m. It is characterised by variable net-to-gross ratio, porosity and permeability.The OWC is found at -4353.8 mTVDSS as obtained from well logs. The reservoir has a base Original Oil In Place (OOIP) of 643 Million Barrels. The aim of this study is to assess connectivity in the Miocene reservoir interval of the “Horse" Field. Based on the analysis of meso-scale architectural elements, three facies sequences were delineated: HM1, HM2, and HM3. Among these sequences, HM2 sand has the best reservoir quality. Available data suggest that this sand form the highest pay sand within the Miocene reservoir interval.The crest of the main anticlinal fold, which forms the major structural trapping system, is moderately faulted. If these faults are sealing, they may effectively compartmentalize the reservoir resulting in poor reservoir connectivity.
