Eni, through its affiliate NAOC (Eni 20%, operator, NNPC 60%, Oando 20%) has made a significant gas and condensate find in the deeper sequences of the Obiafu-Obrikom fields, in OML61, onshore Niger
Delta. The Obiafu-41 Deep well has reached a total depth of 4.374 m
encountering an important gas and condensate accumulation within the
deltaic sequence of Oligocene age comprising more than 130m of high
quality hydrocarbon-bearing sands.The find amounts to about 1 trillion
cubic feet of gas and 60 million barrels of associated condensate in
the deep drilled sequences. The discovery has further potential that
will be assessed with the next appraisal campaign.The well can deliver in excess of 100 million standard cubic feet/day of gas and 3,000 barrels/day of associated condensates, and will be immediately put on-stream to increase NAOC’s gas production.Background: OML 61 is located onshore, south of OML 60. OML 61 covers an area
of 1,499 km² (370,410 acres) and it is the largest License in OER’s portfolio in terms of both production and reserves. Exploration in OML 61 began with the discovery of the Ebocha oil & gas condensate field in 1965.Successful exploration continued in OML 61 with the discovery of the Obiafu-Obrikom (or Ob-Ob), Idu and Oshi fields in the early 1970’s. To date, the License comprises 12 producing fields. All of the producing
fields in OML 61 contain both light and medium sweet oil (25° to
45°API), condensates and natural gas. OML 61 also holds a rich portfolio
of oil and gas prospects and leads mainly targeting the deeper under
explored reservoirs and step-out structures. Historically, oil has been the primary product, but many of the fields contain significant associated and non associated gas reserves which are presently, and are expected to be in the future, significant contributors to gas sales.
Production is primarily from the Ob-Ob, Idu, Oshi, Mbebe, Irri-
Oleh-Isoko and Ebocha fields. Production, Facilities and Infrastructure:
Production, processing and export facilities within OML 61 owned by
the NAOC JV include:203 production and injection
wells with associated flow-lines, of
which 100 wells are active; Five flowstations (Ebocha, Idu, Irri/Isoko, Ob-Ob and Oshi) with processing capacities ranging from 40 Mbbls/d (Oshi) to 120Mbbls/d (Ebocha)548 km of oil pipelines connecting flow stations to the Ob-Ob gas plant and the Brass River Terminal. Ebocha oil centre (120 Mbbls/d liquid export capacity) and the Ogoda manifold (oil gathering hubs); *Ob-Ob gas plant (capacity 1,000MMscf/d).
*One flowstation located at Akri (gross capacity: 50-60 Mbbls/d)
*Ob-Ob gas plant (capacity 1,000 MMscf/d). *One flowstation located at Akri (gross capacity: 50-60 Mbbls/d) *150 MMscf/d capacity gas plant
located at Kwal-Okpai *The Kwale-Okpai Independent Power
Plant (IPP) with capacity of 450 MW The discovery is part of a drilling
campaign planned by NAOC JV and aimed at exploring near-field and deep pool opportunities as immediate time to market opportunities. Eni has been present in Nigeria since 1962, with operated and non-operated production,development and exploration activities on a total of 30,049 square kilometers in the onshore and offshore areas of the Niger Delta. In 2018, Eni’s equity hydrocarbon production amounted to
100,000 boe/day.
