Environmental Impact Assessment and Geological Evaluation of Non-Associated Gas Wells in Forcados-Yokri block, Burutu Area, Delta State, South-south Nigeria.

Аннотация

Forcados-Yokri field is situated in Burutu area of Delta State. Its a large oil and gas province holding large volume of recoverable hydrocarbon. A Geological redevelopment was done to harness the abundant gas contained in it. There is urgent need for Nigeria to shift to cleaner source of alternative energy and reduce its carbon footprint, thus, the block was re-evaluated and re-developed for this gas deposit. The field was thus initiated to supplement gas production for domestic reserve and enhance the industrialization of the region and the country. The field has an expected STOIIP and GIIP (AG + NAG) of 2878 MMstb oil and 2298.7 Bscf of gas respectively. Cluster Jackets, 18" x 5.5km Oil Pipeline 12" x 6.4km Gas Pipeline, 33KV Power Cable Back-up, 8" Gas lift line (North Bank Gas Plant-Yokri Flowstation), new cluster jackets, 33kV Cable from North Bank Manifold, 700V Power Control Cable Ring were connected to the main Pipeline Phase 1. More importantly, 6" South Bank to Forcados Terminal fuel The American Journal of Applied Sciences 10 https://www.theamericanjournals.com/index.php/tajas gas back-up Line, 8 km and 6“ flow line were also companies in the area are expected to key into the real connected to slug catcher at North Bank Gas Processing geoscientific dynamics shaping the world energy Facilities with the existing Associated Gas facilities at the landscape. Climate change is real and can be partly CPF. Findings revealed feasible environmental space for traced to burning of oil and gas of which the gas can be gas production with phytoplankton distribution of converted to cleaner energy. Bacillariophyceae 52%, Cyanophyceae 33%, Before now, the associated gas is commonly flared with Euglenophyceae 7%, Dinophycea 5%, Chlorophyceae 3% impunity in Niger Delta area and globally (Doust and with the zooplankton belonged to six (6) taxa; Omatsola 1989 and 1990) which has serious Copepoda, Hydrozoa, Mollusc larvae, Decapod larvae, consequential harm on the ecosystem with attendant Rotifera, and Chaetognatha. The study concluded the serious public health implication on well-being of feasibility and viability of producing the hydrocarbon communities and the people. Gas utilization has content of about 291MMstb of oil and 94 bscf of gas in increased tremendously in the day-to-day socio- the block area under the prevailing environmental economic activities in Nigeria as a cleaner fuel ranging condition. from domestic cooking gas, alternative source of Keywords: STOIIP= Stock Tank Oil Initially In Place, powering generators to generate electricity, abundant Zooplankton, AG is Associated Gas, NAG is Non- gas-powered stations, gas fired industries, compressed Associated Gas, CPF is Central Processing Facility and natural gas in our vehicles etc. These are due to new GIIP is Gas Initially In Place. Technological and. Geoscientific innovations springing up globally to reduce carbon footprint and make the
