This result is an important exploration breakthrough, establishing a working hydrocarbon system in the Liberian basin.
The well was drilled in block LB‑15 to a total depth of 5,400 metres and encountered good-quality, water-bearing sands in the main objective. In a deeper secondary objective, approximately 8 metres of hydrocarbon pay was intersected and a sample of light oil was recovered.
The well is being plugged and abandoned and the drillship is being mobilised to Sierra Leone to drill the Mercury‑2 appraisal well and the Jupiter exploration well on block SL‑07B‑11.
Tullow has a 25.00% working interest in the licence and is partnered by the operator, Anadarko Petroleum (47.5%) and Repsol (27.5%).
Commenting today, Angus McCoss, Exploration Director, said:
“Whilst this wildcat well made a sub‑commercial discovery at this location, we have gained critical insights which we will now integrate with our extensive 3D seismic data for follow-up drilling in our highly prospective Liberian acreage. We now look forward to the drilling of the high-impact Jupiter and Mercury‑2 wells in Sierra Leone.”
