The rig123.net' target='_blank'>drilling rig with a drilling depth of below 16500 ft can be designed as a helicopter-hoisted drilling rig. Each module of the drilling rig can be kept within 5291 lb, which is suitable for application in mountains, jungles, swamps, beaches, deserts and islands where there is no road access or road conditions do not permit the transportation of large-size components.
With its small size, the designed and manufactured parts and components are easy and convenient for hoisting and transportation.
By using helicopter-hoisted transportation, we can save a lot of time and cost on construction of roads, decrease the destruction of green land, protect the environment, shorten the drilling periods and reduce drilling costs.
