LONDONPremier Oil has issued an update on studies for the Zama oil field development offshore Mexico.

The company is a partner to Talos Energy, containing a large part of the field, which extends into an adjacent block operated by Pemex.

Subsurface analysis of samples and data obtained through the 2018 and 2019 appraisal drilling campaign has confirmed the good quality and properties of the Zama reservoir rocks and the crude oil.

This, combined with the very high resource density and shallow-water setting, could support a recovery factor of more than 50%, (Zama is thought to hold more than 800 MMboe recoverable).

The field will likely be developed with two drilling and processing platforms tied back to an FSO: key elements of the development scheme have been agreed with Pemex.

McDermott Engineering has completed the FEED for the platform jackets and the topsides processing facilities and later this year, an invitation to tender will be issued for detailed engineering, leading to procurement, and construction of the jackets and topsides.

The facilities will be low carbon by design with a GHG intensity estimated at around 16 kgCO2e/bbl over the life of the field.

In addition, Premier has a 30% stake in Mexico offshore block 30, where the Wahoo prospect could be drilled during the second half of 2022.

Off Brazil, the company operates block 717 in the Ceará basin. Plans for the drillship Valaris DS-9 to drill the stacked Berimbau/Maraca prospect last July had to be shelved due to COVID-19.

However, the partners have secured a nine-month extension to the current term for the concession and now expect to drill the well in 1Q 2022.
