Tullow reports disappointing results from Beebei-Potaro-1 well at Kanuku block
TULLOW Oil (UK/Ireland) said on August 5 that drilling operations had been completed at Beebei-Potaro-1, an exploration well at the Kanuku block offshore Guyana, without the discovery of any hydrocarbons.
In a statement, Tullow reported that Rep- sol (Spain), the operator of the block, had used the Noble Regina Allen, a jack-up rig owned by UK-based Noble Corp., to sink the well to a depth of 4,235 metres in 71-metre-deep water. It noted that the well had encountered good-qual- ity reservoir in its primary and secondary drilling targets, but both targets turned out to contain water rather than crude oil, gas conden- sate or natural gas.
As such, Repsol and its partners have now plugged and abandoned Beebei-Potaro-1, Tullow said. It said it would integrate the results from this drilling project into its own subsurface models and discuss the outcome before making any decisions about the next steps at Kanuku.
Tullow had said last year that Beebei-Potaro might contain as much as 200mn barrels of oil equivalent (boe). It also stated that the well would be targeting the Cretaceous horizon, where ExxonMobil (US) has made most of its discoveries at the neighbouring Stabroek block, in the hope of encountering light crude oil there. However, Repsol also identified drilling targets in the Oligocene, Upper Campanian and Lower Campanian horizons.
Equity in the Kanuku project is split between Repsol, the operator, with 37.5%; Tullow, with 37.5%; and TotalEnergies (France), with 25%.
Tullow has talked about farming out part of its stake in the block in order to reduce its risk pro- file and concentrate more intently on its primary assets. It has not yet named any potential buy- ers yet, though, and has stressed that it does not intend to exit the project entirely.
To date, Repsol and its partners have drilled six exploration wells at Kanuku (Carapa-1, Jag- uar-1, Berbice -2, Abary-1 and Mahaica-1 and -2) and have made only one discovery. That find, Carapa-1, consisted of non-commercial reserves of medium crude with a specific gravity of 27 degrees API. ™

Acorn International confirms contract award for EIA of Uaru development project
ACORN International, a Houston-based risk management consultancy, announced on August 9 that it had been contracted to carry out an environmental impact assessment (EIA) for Uaru, the fifth development project at the Stabroek block offshore Guyana.
In a statement, Acorn International said it had won the contract from Esso Exploration & Production Guyana Ltd (EEPGL), the sub- sidiary of US-based ExxonMobil that is leading
work at Stabroek. It did not reveal the value of the contract but said that the scope of work would also include leading the public consulta- tion programme for the Uaru project.
EEPGL is conducting the EIA and public consultation programme in advance of start- ing development work at Uaru. The company is aiming to bring the field – along with Mako, a nearby section of the Stabroek block – on stream in late 2026.
