Upgrading of existing lifting units and equipment for current and workover of wells

Abstract

The main task of well servicing workover units to maintain all active wells fully operable while ensuring compliance with all applicable subsoil protection requirements. The technical equipment of well servicing workover units crews requires automation and robotization, in view of the constant increase in the complexity of well workovers, growing safety barriers and a high proportion of heavy manual labor. Target. In order to automate lifting units for underground workover of wells, a pilot-industrial test project (PIT) «Meh-Brigade» was launched. The purpose of the pilot study is to improve the design of lifting units and equipment, to select the optimal layout for the placement of personnel at the wellhead. Materials and methods. The project involves the improvement and automation of tripping operations by integrating the following main components: cab-transformer, elevator with hydraulic pipe gripper, robot key, mechanized receiving bridge, hydraulic blowout prevention equipment (BOP). Results. A market review was conducted among companies that produce lifting units in the Russian Federation, Europe, China, and the calculation of economic efficiency is being carried out. Conclusion. The pilot test is scheduled for mid-2023.
