3D Shoot Confirms Colibri Prospect Off Jamaica for Tullow and UOG
Tullow has delivered the fast track version of the recently acquired 3D seismic dataset over the Walton-Morant licence offshore Jamaica.
According to Tullow’s licence partner United Oil & Gas (UOG), the high-grade Colibri target, which had previously been mapped on 2D seismic, has been clearly identified on the fast track version of the 3D seismic dataset.
This follows the completion of a 2,250 square kilometer 3D seismic acquisition survey on the licence. United holds a 20% equity interest in the 32,065 sq km Licence, with the remainder held by Tullow.
The 3D seismic survey, which is the first to have been acquired in Jamaica, forms part of a programme focused on de-risking Cretaceous and Tertiary aged clastic and carbonate reservoir targets that have been mapped by Tullow on 2D seismic data. Among these is Colibri, which has been estimated from 2D data to hold gross mean-case prospective resources of over 200mmbbls. The technical case for Colibri has been further strengthened by the recent identification of an active thermogenically derived offshore oil seep to the south of the structure.
Initial opinion is that the fast track 3D seismic data is of excellent quality with the Colibri structure clearly visible on the newly acquired dataset, United said.
Processing and interpretation work is now underway.
United Oil & Gas Plc CEO, Brian Larkin, said: “The work programme to de-risk the 200mmbbl Colibri target on Walton-Morant continues to proceed on schedule and under budget. Being able to clearly identify Colibri on the 3D seismic at such an early stage is highly encouraging and with this in mind, we are looking forward to the processing and interpretation work being completed.”
