Mealey's (June 18, 2015, 4:17 PM EDT) -- COLUMBUS, Ohio — An oil well services company being sued by a drilling company for damages to an oil and gas well filed a brief Sept. 19, 2014, in Ohio federal court, arguing that the drilling company should not be allowed to present its expert witnesses on grounds that they were “retained or specifically employed” and were not witnesses that actually observed any of the alleged damage (Express Energy Services Operating LP v. Hall Drilling LLC, No. 14-0204, S.D. Ohio).
