6. Suspended Well Costs

The following table reflects the Company’s capitalized exploratory well costs on completed wells as of and during the three months ended March 31, 2015. The table excludes $60.3 million in costs that were capitalized and subsequently expensed during the same period.

	Three Months Ended March 31, 2015

The following table provides an aging of capitalized exploratory well costs based on the date drilling was completed and the number of projects for which exploratory well costs have been capitalized for more than one year since the completion of drilling:

	March 31, 2015		December 31, 2014

	(In thousands, except well counts)
Exploratory well costs capitalized for a period of one year or less	$	13,723	$	16,814
Exploratory well costs capitalized for a period of one to two years	44,655		40,865
Exploratory well costs capitalized for a period of three to six years	169,129		169,035
Ending balance	$	227,507	$	226,714
Number of projects that have exploratory well costs that have been capitalized for a period greater than one year	4		5

As of March 31, 2015, the projects with exploratory well costs capitalized for more than one year since the completion of drilling are related to the Mahogany, Teak (formerly Teak-1 and Teak-2) and Akasa discoveries in the West Cape Three Points (“WCTP”) Block and the Wawa discovery in the DT Block, which are all in Ghana.

Mahogany— In March 2015, we submitted a declaration of commerciality to Ghana’s Ministry of Energy and Petroleum and expect to submit a PoD concerning the Mahogany discovery later this year.

Teak Discovery—We are currently in discussions with the government of Ghana regarding the declaration of commerciality for the Teak discovery. Upon resolution of such discussions and declaration of commerciality, a PoD would be prepared and submitted to Ghana’s Ministry of Energy and Petroleum, as required under the WCTP petroleum contract. The Teak-1 and Teak-2 discoveries are being treated as a single discovery area.

Akasa Discovery—We performed a drill stem test and gauge installation on the discovery well and drilled one appraisal well, the Akasa-2. We are currently in discussions with the government of Ghana regarding additional technical studies and evaluation that we want to conduct before we are able to make a determination regarding commerciality of the discovery. If we determine the discovery to be commercial, a declaration of commerciality would be provided and a PoD would be prepared and submitted to Ghana’s Ministry of Energy and Petroleum, as required under the WCTP petroleum contract.

Wawa Discovery—We are currently reprocessing seismic data and have acquired a high resolution seismic survey over the discovery area. Following additional evaluation and potential appraisal activities, a decision regarding commerciality of the Wawa discovery is expected to be made by the DT Block partners in 2016. Within six months of such declaration, a PoD would be prepared and submitted to Ghana’s Ministry of Energy and Petroleum, as required under the DT petroleum contract.
