UK-based Zeta Petroleum has announced that the Jimbolia-100 appraisal well is expected to reach its target depth of 2,590m in five days.

The company is drilling the appraisal well on the Jimbolia oil concession in Romania targeting the Jimbolia Veche oil discovery which has two hydrocarbon bearing intervals and a current Pmean contingent resource of 1.72 million barrels.

Drilling of the well began on 31 December 2012 and has reached the second casing point depth of 2,404m. Casing of the well has been run and cemented to a depth of 2,391m.

Upon completion of the cementing job, the well will be logged before drilling through the targeted oil reservoir.

The company will take another 15 days to complete logging and testing operations and if successful the well will be completed as a production well.

NIS Petrol SRL, a wholly-owned subsidiary of NIS Gazprom Neft, is the operator with 51% interest in the Jimbolia oil concession. Zeta Petroleum and Armax Gaz each hold 39% and 10% interest each in the concession.
