Petronas discovers two deepwater oil discoveries in Salina Basin, offshore Mexico


KUALA LUMPUR – Petroliam Nasional Bhd’s  (Petronas) PC Carigali Mexico Operations S.A. de C.V.  (PCCMO) has discovered two deepwater oil discoveries in Mexico from the Polok-1 and Chinwol-1 exploration wells in Block 29, located in the Salina Basin, offshore Mexico.

Following these two discoveries together with last month’s oil discovery in the Monument exploration well, offshore United States Gulf of Mexico, marks three successful discoveries in a row.

“It is a significant milestone for Petronas and its ventures in the Americas. We are thrilled about the two discoveries which prove our continued focus in pursuing opportunities to grow our resources and reserves portfolio in Mexico’s prolific basins.

“Together with our partners, we look forward to further assessing the data to determine the commercial potential of these discoveries,” Petronas’ Vice President of Exploration, Upstream, Emeliana Rice-Oxley said in a statement today.

The Polok-1 well was safely drilled to a depth of 2,620 metres and encountered 200 metres of net oil pay in Lower Miocene deep marine clastic reservoirs.

Meanwhile, the Chinwol-1 well, located 12 kilometres from Polok-1, was drilled to a depth of 1,850 metres and encountered net oil pay of 150 metres in the lower Pliocene formation.

Drilling of the Polok-1 exploration well had commenced from Feb 29, 2020, consecutively followed by the drilling of the Chinwol-1 well.

The Polok-1 and Chinwol-1 wells are located in water depths of 584 metres and 464 metres, respectively, approximately 75 kilometres northwest off the coast of Tabasco.

Through PCCMO, Petronas currently holds an interest in 10 exploration blocks across Mexico’s three main basins, with a total area of approximately 22,000 square kilometres, of which PCCMO is the operator in five of the blocks.
