LONDON  Tullow Oil expects to produce first oil production from the Jubilee South East development offshore Ghana in the second half of the year, the company said in its latest results statement.

Despite the inflationary environment and COVID-19-related issues during 2020-22, the project remains within the original project, Tullow added.

Two wells were drilled in the Jubilee South East area in the second half of 2022 and a third this January. Results from the main target reservoir are in line with expectations, with upside from deeper appraisal target reservoirs that encountered oil; these should provide resources for future development.

The wells will start producing following installation and tie-in to the Jubilee South East Project subsea infrastructure.

Tullow is predicting average oil production from the entire Jubilee Field of about 95,000 bbl/d this year and climbing above 100,000 bbl/d once all five new wells drilled are online, made possible by increased water and gas handling capacity on the FPSO.

At the TEN fields nearby, Tullow’s near-term focus is on sustaining strong operational uptime and improving gas handling on the FPSO, reducing flaring and increasing gas injection to support oil production.

Improvements to the gas processing facilities will take place during a planned maintenance shutdown in the third quarter.

The longer-term plan for TEN is to monetize remaining resources through infill drilling, phased development of new areas near existing infrastructure, development of the gas resources and drilling further prospective resources.

Tullow is assessing a restructuring of the FPSO cost base to support sustained cost efficiency in production operations and expects to submit a plan of development to the government of Ghana later this year.

Elsewhere, the company is a partner to CNR International on the Espoir Field offshore Côte d'Ivoire. Remediation work on the FPSO will continue through 2023, and a 4D seismic survey is due to be acquired to support planned infill development drilling and mature future investment projects.

Offshore Argentina, the company has secured a two-year extension to Block MLO-122 in Argentina.

Last year, Tullow’s offshore decommissioning activity included removal of three platforms at the Murdoch Hub and the Ketch platform, all in the southern UK North Sea. Removal of the Ketch pipeline should finish later this year.

In the same region, 11 Schooner Field wells were plugged and abandoned (P&A), and P&A operations have now started at the Boulton Field as part of an eight-well campaign in the CMS area.

Finally, the Banda and Tiof decommissioning campaign, which started offshore Mauritania last December, should conclude by mid-2023.
