BANGALORE, Aug 11 (Reuters) - Oil and gas explorer Melrose Resources Plc (MRS.L) said it successfully drilled a second well in the Kaliakra field at its exploration license in the Black Sea, offshore Bulgaria, raising its combined reserves estimate to 100 billion cubic feet.

The drilling results indicate that the Kaliakra field's most likely reserves are 57 billion cubic feet (bcf) and confirmed the Kavarna field reserves of 24 bcf, Melrose Resources said.

"We believe that the discovery of further gas in close proximity to the existing Melrose-operated Galata platform helps de-risk the development of the Kavarna and Kaliakra gas fields," Numis analyst Sanjeev Bahl said in a note.

Bahl has an "add" rating on Melrose Resources stock.

The company would either develop Kavarna this year and Kaliakra early next year or might develop both fields together in the second quarter next year, and targets production in the third quarter, it said.

"The sort of production rate that we think we could get from the two wells, one on each field, would be say 50 million cubic feet per day," Chief Executive David Thomas told Reuters.

"We have another well on Kaliakra and if we choose to complete that, we could probably get 60 million to 70 million cubic feet per day for the initial rate."

The company also said it was in contact with the new Bulgarian government to facilitate the agreements required to begin the Galata gas storage project.

The project was delayed by a few months due to elections.

"We don't have a firm timing on when the approval would take place. We had expected this to take place in the third quarter but since we are starting with a new administration, there could be delays on that," Thomas said.

EGYPTIAN PUSH

Melrose Resources, which had planned to invest about $165 million in its core area assets in 2009, said it expected to spend about 60 percent to 65 percent of this amount in Egypt.
