Edinburgh-registered explorer confirms discovery of new 1bn-barrel oil field off Mexico

An oil and gas exploration company registered in Edinburgh has confirmed that it has found a 1bn-barrel oil field in Mexico.

The Zama-1 exploration well offshore Mexico, has now completed drilling operations in the final hole section, reaching a total depth of 4,108 metres (13,478 feet). 

The logging results confirmed that the previous hole section had reached the base of the reservoir section, with an oil-down-to in the well of 3,380 metres (11,089 feet) with no subsequent penetration of an oil-water-contact.

Premier Oil –  together with its joint venture partners Talos Energy (Operator) and Sierra Oil & Gas – is now undertaking analysis of all the data gathered from the Zama-1 well and evaluating the best way to appraise and then develop this ‘world class’ discovery.

Premier’s estimate of the initial gross oil in-place volumes for the reservoir was as previously announced, in excess of 1 billion barrels of oil.  The gross oil bearing interval in Zama-1 is over 335 metres (1,100 feet).  The well was completed on time and budget and has been suspended as a potential producer.

Meanwhile in the North Sea, the Burgman field in the Premier-operated Catcher project has been drilled and is currently being completed.  This is the last of the 12 wells scheduled for completion pre-first oil. 

As with other wells in the programme, the well is currently ahead of time, under budget and with reservoir result ahead of prognosis.  Ten of the 12 wells have been tied in, with the final two tie-ins scheduled ahead of first oil from the field.  

Once the current well is completed, the Catcher project will have delivered four wells on each of the Catcher, Varadero and Burgman fields ahead of schedule and the rig will then be moved back to Catcher at the end of August for the next batch of four production wells.
