The Montserrado-1 exploratory well off Liberia is a noncommercial light oil discovery that established a working hydrocarbon system in the Liberian basin.
Operated by Anadarko Petroleum Corp., Montserrado went to 5,400 m in the LB-15 block and encountered good-quality, water-bearing sands in the main objective. It intersected 8 m of hydrocarbon pay in a deeper secondary objective and recovered a sample of light oil.
Anadarko will plug the well and move the drillship to Sierra Leone to drill the Mercury-2 appraisal well and the Jupiter exploratory well on Block SL-07B-11.
Liberia Block LB-15 interests are Anadarko 47.5%, Repsol 27.5%, and Tullow Oil PLC 25%.
