Repsol has made two significant offshore oil discoveries in Mexico’s deep water with its Polok-1 and Chinwol-1 exploration wells in Block 29 in the Salina Basin. Both wells confirmed high quality reservoirs with excellent properties, encountering net oil pay of 200 meters and 150 meters respectively.

With these finds Repsol has posted six discoveries from six wells drilled worldwide this year, uncovering combined gross resources in excess of 650Mboe, in the US, Mexico and Colombia.

The discoveries extend Repsol’s long-term exploration track record in Latin America and North America. Repsol applies the latest-generation tools and technology in this field, combined with the skills of an experienced exploration workforce.

Both wells in Mexico were drilled below their cost and time estimations with the highest standards for health and safety and under strict health protocols to avoid the propagation of Covid-19 to both offshore and onshore facilities.

The consortium partners Repsol (30%, operator) PC Carigali Mexico Operations, the Mexican subsidiary of PETRONAS (28.33%), Wintershall DEA (25%) and PTTEP México E&P Limited (16.67%) will evaluate all data collected in the wells to prepare the discoveries’ appraisal plan, to be submitted to Mexico’s hydrocarbons regulator CNH before the end of the year.

The discoveries in Mexico’s Block 29 are just 12 km apart from each other, and 88 kilometers (55 miles) from the Mexican coastline of Tabasco, in water depths of approximately 600 meters (1,969 feet).

The Polok-1 exploration well was drilled to a total depth of 2,620 meters and encountered more than 200 meters of net oil pay from two zones in the lower Miocene. The Chinwol-1 exploration well was drilled to a total depth of 1,850 meters and encountered more than 150 meters of net oil pay from three zones in the lower Pliocene.

Wireline Formation testing performed on both wells has shown good flow capacity in multiple stations along the Miocene and Pliocene reservoir units.

Repsol recently received approval from the CNH to drill the company’s third deep water exploration well offshore Mexico, located in Block 10 offshore Veracruz, which will be spudded in the following days using the same Maersk Deep Water Valiant drillship.

  Semisub rig owner Dolphin Drilling has inked a new contract with Peak Petroleum in Nigeria for its 1974-built Blackford Dolphin.   The firm contract, which follows the letter of award in January, gives the Euronext Growth-listed owner of three rigs the potential to extend the unit’s backlog by a minimum of 120 days and up to 485 days. The deal adds to and will be a direct continuation of the previously announced 12-month contract with General Hydrocarbon Limited (GHL).   Øystein Stray Spetalen-backed company said the effective dayrate associated with the minimum firm period of the contract is $325,000, including the mobilisation fee.   “The final award of the contract for Blackford Dolphin shows the opportunities in Nigeria at a strong dayrate, in addition to building on the backlog for the rig. It also underlines the attractiveness of our assets, and we look forward to returning to revenue-generating operations in 2023,” noted Bjørnar Iversen, CEO of Dolphin Drilling.   Source: Dolphin   Join our mailing list here We are #1 on Google and Bing for the "Largest Mobile Energy Network" Come join our community!
