Pemex is attracting interest from a range of players for a pair of tenders covering the revitalisation of mature fields throughout Mexico.

While the state-led company gained the ability under Mexico's energy reform to farm out assets and take on new partnerships, the company has also released revamped service contract processes aimed at revitalising production while maintaining operatorship.

Pemex launched the first such proceeding for the San Ramon and Blasillo fields in recent months, a process designed as the heir to previous service contracts but with more attractive terms for contractors.

A total of 11 companies have submitted pre-qualification documents for that process — Baker Hughes, Dowell Schlumberger, ENX Compressors, Estratego Servicio Empresariales, Grupo R, Iberoamericana de Hidrocarburos, Servicio e Ingeniera en Tecnologia Electronica, Servicios Integrales GSM, Sinopec, Southern Procurement Services and Tracovesa.

The results of this pre-qualification process are to be released on 24 March. Once finalised, the service contract would run for 10 years.

The two blocks boast a possible resource base of 26.7 million barrels of oil equivalent, with opportunities to increase both production and recovery factors, with low production costs.

The hydrocarbon is light oil, 31 to 35 degrees API, with infrastructure nearby.

Pemex has also released shortlists for separate tenders to perform revitalisation work on four packages of shut-in wells across the country.

That process has seen delays after the presentation of offers was originally planned for last month.

The state-led Mexican oil company is still working through questions surrounding large volumes of well and other data released into the data rooms, with the next clarification meeting scheduled for 14 March.

The wells to be addressed were split into four groups.

Group 1's work to be assigned covers 38 wells in the BS02 and BS04 production assets in the south-east of Mexico. Baker Hughes, Dowell Schlumberger and Grupo R pre-qualified. Halliburton and Sinopec expressed interest but were disqualified.

Group 2's work to be assigned covers 37 wells in the BS01 and BS03 production assets in the south-east of Mexico, with an emphasis on revamping Mesozoic reservoirs. Alpha Energy, Baker Hughes, Dowell Schlumberger and Grupo R pre-qualified. Halliburton and Sinopec expressed interest but were disqualified.

Group 3 covers 47 Tertiary wells in the BS01 and BS03 production assets in south-east Mexico. A total of seven pre-qualified — Alpha Energy, Baker Hughes, Dowell Schlumberger, Grupo R, Grupo Vordcab, Quimica Apollo and Sarreal expressed interest via consortia. Companies thrown out by the process were Halliburton, Reservoir Production Management, Sinopec and Voya Ger Light Energy of Mexico.

Group 4 covers 101 wells in the BN02 production area in northern Mexico and the BN03 area near the central coast. Only Baker Hughes, Dowell Schlumberger and Sarreal pre-qualified. Seven companies were disqualified — Fortaleza, Geolis, Halliburton, Reservoir Production Management, Sinopec, Tarco and Weatherford.
