The company’s sales revenue decreased 25.5% to RON43.2 million, from RON58 million in January-June 2013.

The weaker results are due to “the unfavorable economic climate with oil price volatility and changes in the regulations regarding the authorization of oil well constructions,” Rompetrol Well Services said in its financial report.

KMG International, the former Rompetrol group, owns 73% in Rompetrol Well Services, whose shares are listed on the Bucharest stock exchange. Wednesday morning, the company’s shares traded flat on the day, at RON0.549 per unit. (EUR1=RON4.4425)
