  • Successfully completed Appraisal Programme in Block 7 in Mexico confirms significant recoverable volumes. 

The consortium of offshore Block 7 in Mexico has successfully completed the Zama appraisal campaign. The campaign comprised two appraisal wells (Zama-2 and Zama-3) and a vertical side track (Zama-2 ST1) which was flow tested. Based on the information collected to date, Zama is estimated to hold recoverable volumes in the range of 400 million to 800 million barrels of oil equivalent. 

Hugo Dijkgraaf, Chief Technology Officer of Wintershall Dea comments: “We are very pleased with the results of the entire appraisal campaign. It confirms the significant recoverable volumes of this world-class discovery. Zama is an outstanding asset that offers very attractive opportunities. Together with our partners we are now looking forward to select the best development concept for the field.” 

Block 7 is located in the prolific Sureste Basin offshore Mexico containing Zama, one of the largest shallow water discoveries of the past 20 years globally. 

The latest appraisal well, Zama-3, has proven the lateral continuity of the reservoir 2.4 kilometres to the south of Zama-1 with the quality of the reservoir sands encountered at the upper end of expectations.  

A comprehensive set of data was acquired during the appraisal campaign, including high resolution wireline logs, extensive fluid sampling and pressure data, together with the recovery of over 400 metres of core and a successful drill stem test.  

Juan Manuel Delgado, Managing Director Mexico at Wintershall Dea said: 
“I am very delighted, that we completed the appraisal campaign without any lost time incidents and significantly under budget. We now achieved an important milestone towards the final investment decision of the development project.”

In Mexico, Wintershall Dea currently operates the onshore Ogarrio oil field, in partnership with Pemex. Furthermore, Wintershall Dea holds extensive acreage in ten exploration blocks in the Tampico Misantla and Sureste Basins. The company is operator in three of the ten exploration licences.
