Drilling at the Hassa-1 prospect in the Stabroek block offshore Guyana has failed to encounter hydrocarbon resources, ExxonMobil said on Friday in response to a question from OilNOW.
“The Hassa-1 exploration well in the Stabroek block did not encounter hydrocarbons in the primary target reservoirs,” Janelle Persaud, ExxonMobil Guyana Public and Government Affairs Advisor said. “However, the well did encounter hydrocarbons in other intervals.”
Persaud said the company is evaluating the data which will be integrated into its regional subsurface interpretation and modelling.
“This serves as a reminder that geologic risk is inherent to frontier oil and gas exploration activities. Nonetheless, ExxonMobil remains committed to evaluating the potential in our offshore Guyana blocks using our world-class technology and technical capabilities,” she told OilNOW.
Hassa-1 is located approximately 30 miles east of the Liza field and was drilled by the Noble Don Taylor.
The Don Taylor has now moved on to conduct development drilling for Phase 2 of the oil production operations at the Liza field.
ExxonMobil has to date made 18 discoveries on the block, amounting to approximately 9 billion barrels of oil equivalent resources.
