Randeep Grewal, Chairman and Chief Executive of Greka Drilling, commented:

“The first half of 2013 has been particularly slow with most of our teams focused on training and rig maintenance rather than drilling. Whilst the first half of the year has historically included a very slow first quarter with Green Dragon Gas, the Company has successfully secured third party contracts to compensate for this seasonality. The Company had readied rigs for mobilization for third parties but was delayed by the lack of site availability from the new clients thus deferring the drilling contracts. Additionally, the new clients are monitoring the production performance from pilot wells drilled by the Company before initiating their drilling programs under their contractual commitments. Our client, Green Dragon Gas, reduced its drilling activity while focusing on resolving its title issues and thus released a number of rigs, which we expect to be redeployed in the latter part of the year following the recent resolution of this issue.
