Drilling operations in Trumbull County could begin in early 2013, a BP spokesman told an audience Monday night in Vienna.
Bruce Abbuhl, Ohio program manager for BP, said the energy giant has little information on how productive its newly leased 84,000 acres in Trumbull County might be, the Youngstown Vindicator reported.
About 1,900 landowners have agreed to lease terms in Trumbull County with BP.
The company is reportedly paying a signing bonus of $3,900 per acre and royalties of 17.5 percent, according to reports. The company has not disclosed financial terms.
The company is meeting through April 16 with individual landowners in Salem to sign leases.
The company is setting up an office in Warren that will employ about 40 people to conduct title searches on the properties.
By early fall, BP expects to have prepared development plan, surveyed lands for initial drilling, collected baseline water samples and developed a water-management strategy, Abbuhl said.
