Abstract
Floating Gas to Power (FGTP) has been identified as a frontier concept for stranded gas field development. Instead of converting dry gas to LNG (FLNG Concept), the gas is used offshore for generating electricity as an end product. Offshore to Onshore electric power transmission is usually by marine or subsea cabling. The electricity is eventually distributed into a large utility power grid. As an emerging economy with a population expected to keep growing, the question of how to bridge Nigeria’s continuously increasing power deficit has become topical. Furthermore, offshore Nigeria, stranded gas reserves are found in difficult locations and in such quantities as to render their exploitation through conventional means economically unfeasible. The main objective of the study was to perform a Niger delta basin-wide screening: identify and rank Nigeria’s most prospective stranded offshore gas fields and perform a first-order evaluation of the scale of FGTP possible contribution to alleviating the country’s power deficit. A conventional exploration risking approach was used to evaluate, rank and risk offshore Niger Delta stranded gas fields for hydrocarbon fluid type, location, water depths, and distance from shore, terrain, accumulation size, and average reservoir properties. All relevant data public domain data have been analyzed. 765 fields in the Niger Delta basin have been evaluated and ranked. 79 of these fields were revealed to possess good to very good FGTP Project potential. A shortlist of the most prospective fields was then enumerated and ranked. Based on the results of this study, we believe we have localized some of the more interesting "sweet-spots" for FGTP Offshore Nigeria, from an industry perspective. Technological developments, the gas price and the continued increase in demand for energy will define if and when these resources will be exploited on a large scale. Furthermore, the study shows that the FGTP option in the Offshore Nigeria space deserves thorough scrutiny and further studies to evaluate its techno-economic feasibility. It could prove an economical and environmentally friendly option for energy generation. If properly harnessed, it could resolve the epileptic power supply problem in Nigeria, generate huge potential revenue for
the government, and create numerous employment opportunities.
