In a significant milestone for the Ubeta Gas Multiphase Onshore Pipeline Project, Oilserv Limited, an indigenous EPIC company with global expertise, struck the first welding arc. This unprecedented achievement has marked the official commencement of welding activities on the 16-inch pipeline project.
“The project, executed for TotalEnergies EP Nigeria Limited, is progressing in line with the agreed delivery schedule, reinforcing Oilserv Limited’s commitment to timely, safe, and quality project execution. This milestone reflects the dedication of our project team and partners in advancing infrastructure that supports Nigeria’s energy goals.” Oilserv stated.
TotalEnergies has on June 20, 2024, launched the Ubeta Gas Development project; the significant purpose of the multi-billion naira project is to supply gas to the Nigeria LNG Liquefaction Plant and basically the train 7.
The Ubeta gas condensate field is located about 80 km northwest of Port Harcourt in Rivers state, the OML 58 license contains two fields currently in production, the Obagi oil field and the Ibewa gas and condensate field. OML58 gas production is processed in the Obite treatment center and supplied to both the Nigerian domestic gas market and to Nigeria LNG (NLNG) plant.
Also located in OML58, the Ubeta gas condensate field will be developed with a new 6-well cluster connected to the existing Obite facilities through a 11 km buried pipeline. Production start-up is expected in 2027, with a plateau of 300 million cubic feet per day (about 70,000 barrels of oil equivalent per day including condensates). Gas from Ubeta will be supplied to NLNG, a liquefaction plant located in Bonny Island with an on-going capacity expansion from 22 to 30 Mtpa, in which TotalEnergies holds a 15% interest.
Ubeta is a low-emission and low-cost development, leveraging on OML58 existing gas processing facilities. The carbon intensity of the project will be further reduced through a 5 MW solar plant currently under construction at the Obite site and the electrification of the drilling rig. TotalEnergies is working closely with NNPCL to enhance local content, with more than 90% of manhours which will be worked locally.
“Ubeta is the latest in a series of projects developed by TotalEnergies in Nigeria, most recently Ikike and Akpo West. I am pleased that we can launch this new gas project which has been made possible by the Government’s recent incentives for non-associated gas developments. Ubeta fits perfectly with our strategy of developing low-cost and low-emission projects, and will contribute to the Nigerian economy through higher NLNG exports”, said Mike Sangster, Senior Vice President Africa, Exploration & Production at TotalEnergies
UBETA MAIN DEVELOPMENT PROJECT
The Ubeta Main Development project includes Basic Engineering and Detailed Engineering comprises development of Ubeta Gas Field and tie-in to existing Ubite Treatment Center inlet manifold and associated brownfield activities.
This requires Design of a WHCP & HPU For hydraulic supply and control of all actuated valves fully monitored and controlled from the Obite CCR, fully rated (240 barg) unmanned well pad, the Ubeta Production Cluster (UPC) with facilities consisting of 6 Nos production wellheads and 6 spares for future, 6 Nos flowlines (NPS 8) from wellheads to 16 production manifold.
2.5MSm3/d flowline for each well, One MPFM per producing well flowline for Well Multiphase fluid production metering and testing. A 16’production manifold which gathers the producing fluid prior export to OTC via 16′ CS pipeline and 10MSm3/d expected at peak rate. A pig launcher for the 16′ CS export pipeline pigging purpose, 11Km pipeline buried at 1.2m depth.
A mobile maintenance flare (for manual depressurization and maintenance activities) as well pad is fully rated to WHSIP with no EDP. A Chemical injection package (Corrosion inhibitor) to protect the 16 CS pipeline material against corrosion and also a Mobile chemical injection packages (Methanol), Injected upstream wellhead choke valve to avoid the risk of hydrate formation during a cold start-up.
No power generation at UPC, Power supply to UPC Facility is from existing Switchboard located at OTC through an underground HV power cable with provision for EDG for emergency use – day tank only.
