UK oil explorer Tullow Oil said has found gas condensate in the Tweneboa-3 appraisal well in the Deepwater Tano license offshore Ghana.
Tullow said that the results of drilling, wireline logs and samples of reservoir fluids, along with with the well’s down-dip position confirms the greater Tweneboa area resource base potential.
Tweneboa-3, which is located over 6km south-east of the Tweneboa-2 well, was drilled by the Deepwater Millennium drillship to a total depth of 3,906m in a water depth of 1,601m.
The well tested separate areas of the Tweneboa field, hitting a 9m column of pay and a 34m column of pay.
The well was sidetracked 550m west, targeting the significant Ntomme anomaly, an area of strong seismic response.
The well will be suspended for future use in the field development Once the operations are completed.
The rig will remain in the Deepwater Tano block to drill the top-hole section of the Tweneboa-4 appraisal well, which will then be suspended before moving to drill the Enyenra-2A well.
Tullow operates the Deepwater Tano license with a 49.95% stake in the prospect.
