Calvalley’s producing fields are some of the highest-producing and most promising in the Republic of Yemen.
If all exploration potential and contingent resources are included in the analysis it is estimated that as little as 3.7% of Calvalley’s total hydrocarbon potential has been extracted in the last 14 years, making Block 9 the most attractive asset in Yemen at the present time
This constitutes a tremendous opportunity and an exciting challenge. Calvalley’s technical expertise, strong investor commitment and local knowledge make us well-equipped to produce successful results.

Calvalley has a large and varied prospect portfolio in Block 9, comprising 41 prospects and leads in Block 9 with drill-ready prospects (multiple proven play types) located across the block.
This constitutes a tremendous opportunity and an exciting challenge. Calvalley’s technical expertise, strong investor commitment and local knowledge make us well-equipped to produce successful results.
The most significant appraisal discovery in Block 9 is the Qarn Qaymah field, in addition to 41 prospects and leads with drill-ready prospects (multiple proven play types on the existing 2D seismic data set) located across five sites: Rashedah, Gadafir, Lokhaymer, Saghira and Ras Noor South.
Qarn Qaymah field is located in the northeastern part of Block 9, extending over an area of 85 km2 within the block and into the adjacent Block 72. The Qarn Qaymah field contains two discoveries:
Tested gas condensate in both QQ-1 and QQ-2 wells
QQ-1: 10 mmcf/d and 657 bcpd
QQ-2: 3.5 mmcf/d and 200 bcpd
Proven 380m+ of hydrocarbon column
QQ-2 tested with oil rate of up to 2,964 bbl/d (43° API)
Estimated Unrisked OOIP 304 MM bbl
The significant size of the Qarn Qaymah reservoir and the presence of the fracture network in the basement of the structure is highly encouraging. The company is optimistic that results of pending lab analyses of formation fluids will indicate the potential of down‐hole chemical treatment to prevent future depositing of paraffinic compounds and asphaltenes, a common production-impairment phenomenon in many oil fields worldwide.
