Profile: Le-Mack (Oilfield Rentals) Ltd. is a provider of oilfield consultancy service. We provide control well pressures during various wireline, slickline, or coiled tubing operations that permit fluids to be circulated for well control or pump down operations particularly in high deviation or high pressure wells. Our split grease tube sealing system can be readily checked for wear and enables rig up, rig down, tool, and cable head changeover times to be kept to a minimum.
