Tulcan EPC owns and operates two marginal fields in the Niger Delta region, SouthWestern Nigeria.
TSB Field Overview
The Tom Shot Bank Field is located within PPL244 (formerly OML-14), situated in the shallow offshore region of the Calabar River in Akwa Ibom State. Covering an area of approximately 21 km², the field has both 2D and 3D seismic coverage, and lies in water depths of about 30 feet.
Discovered by SPDC in 1980, the field was first drilled to a depth of 8,100 feet above the horizontal (ftah), encountering seven hydrocarbon-bearing sands, identified as U2, U3, U4, U5, U6, U7, and U9. The discovery well, TSB #1, was drilled in 1980 by Shell and successfully tested multiple gas and oil sands. However, the well was temporarily suspended after drilling.
A second well, TSB #2, was drilled in 1989 by Shell. This well encountered the upper four gas and oil-bearing reservoirs but crossed a major fault before penetrating the key lower oil reservoirs. Consequently, it was plugged and abandoned.
The field lies within a water depth ranging from 5 to 15 meters, across an area of about 23 km² in the offshore region of the Nigerian Niger Delta. It benefits from both 2D seismic surveys and a 3D survey that spans the entire OML-14 block. The 3D seismic data was reprocessed to a Pre-Stack Depth Migration (PSDM) in 2008, improving imaging quality.
In November 2011, TSB-1 was re-entered, logged, and tested, yielding an un-reconciled production rate of 250–450 barrels of oil per day (BOPD), a gas-oil ratio (GOR) of 863 standard cubic feet per stock tank barrel (scf/stb), and a 40.6° API gravity in the U7 zone via Drill Stem Test (DST).
The Tom Shot Bank Field is in close proximity to several prolific producing fields, including Frontier Oil’s Uquo gas field, Universal Energy’s Stubb Creek, Moni Pulo’s Abana Field, and Mobil’s Qua Iboe Terminal. Notably, Moni Pulo’s Cross River Field is located within the same geological compartment as the Tom Shot Bank Field.
Odimodi Field Overview
The Odimodi Field, located within PPL 226 (formerly part of OML 62), lies in the southern swamp area of Delta State. Covering an area of 94 km², the field benefits from both 2D and 3D seismic coverage. It was discovered in 1967 through the drilling of the Odimodi-1 well, which reached a total vertical depth (TD) of 12,988 feet and encountered one hydrocarbon-bearing sand.
Positioned in the northwestern part of OML 62, Odimodi is situated within the coastal swamp of the Niger Delta Sedimentary Basin. It is located near the Yokri Focardos field and is approximately 11 km from the Beniboye Field. Notably, the field is also in proximity to key oil and gas infrastructure, including the Odidi Gas Plant (about 25 km away) and the Focardos Yokri Production Facility (approximately 17.5 km away).
The field development strategy by Tulcan E&P aims to unlock the value of the Odimodi Field through de-risking and continuous development to ensure robust project economics. This will be achieved through a phased development approach and ongoing subsurface studies, including prospective evaluations. The strategy also includes appraisal and exploration well drilling, the innovative application of both conventional and enhanced oil recovery methods, as well as the use of integrated well completion techniques.
