Yaterra Ventures Corp. announced that final terms are being negotiated on a work over lease agreement which includes more than 150 wells on over 1,600 acres of land in Western Pennsylvania, part of the much desired Marcellus Shale which extends throughout much of the Appalachian Basin. The company execs state that the majority of these wells are production capable but were shut in due to financial constraints of the previous owners. It is noted that these leases are currently producing between 6-10 barrels of oil per day (BOPD) and with the initiation of development phase 1, the company is confident is can increase this level to 20-40 BOPD. The work over and treatment of each well is considered both low risk and low cost, estimated to require less than a $20,000 investment to bring each well up to its maximum potential.
