The well encountered a total gross hydrocarbon column of 107ft (comprising 82ft in the D2 and 25ft in the LD1A reservoirs).
The greater than expected hydrocarbon column has lead to an upgrade in D2SL volumetrics post Ebok-6 to 135mmbbls STOIIP of which 23mmbbls is estimated as recoverable (versus pre-drill estimates of 33mmbbls STOIIP, 8mmbbls recoverable). This increases total 2P Ebok recoverable reserve estimates to 116mmbbls.
Completion of the Ebok-6 appraisal well represents the conclusion of the pre-development Ebok appraisal phase (Ebok-4, Ebok-5 and Ebok-6 wells). Based on a pre farm-in gross reserve estimate of 25 mmbbls, appraisal drilling to date has confirmed an incremental 91 mmbbls recoverable through a 100% drilling success rate.
Following the completion of the Ebok-6 well, work on development phase 1a commenced on December 9, 2009. The first phase development plan comprises five horizontal oil production wells in the D2 reservoir, one horizontal oil production well targeting the D1 reservoir and one water injection well in the central Fault Block 1 and Fault Block 2 areas of the field.
All wells will be drilled from a single field location via a Well-head Support Structure (WSS) and mobile offshore production unit (MOPU). Fabrication of the WSS is complete and is in transit for delivery to the project.
The company is in the process of finalising contract discussions on the production facilities. Associated gas produced will be utilised as fuel for the facilities’ power generation and as gas lift to assist well productivity.
After the completion of the initial development phase, the subsequent development phases will incorporate the full development of the D2 Southern Lobe, D1 reservoir (Fault Block 1 & 2 areas), and Fault Block West, whilst appraising the potential within the West Flank Qua Iboe structure, the D2 Upside Extension and the Fault Block North (cumulative total of 212mmbbls STOIIP and 66mmbbls recoverable).
