Abstract: An efficient and eco-friendly oil drilling system includes at least one storage tank, an initial surface drilling system and a subsequent drilling system, a plurality of rig mud pumps, and a drilling rig. The plurality of rig mud pumps is in fluid communication with the drilling rig as the drilling rig is in fluid communication with the at least one storage tank. The initial surface drilling system that drills a surface hole for an oil well and the subsequent drilling system that drills a borehole for the oil well are selectively in fluid communication with the plurality of rig mud pumps, where the initial surface drilling system is utilized prior to the subsequent drilling system to optimize the efficiency of the drilling process.

Abstract: A lifting apparatus for lifting a heavy object. The lifting apparatus including a frame assembly having a pair of side beams spaced parallel to one another. A sliding sheave assembly is mounted to the frame assembly. The sliding sheave assembly is positioned between the pair of side beams. The sliding sheave assembly has a first shaft with a plurality of first sheaves mounted thereto and a second shaft with a plurality of second sheaves mounted thereto. The first and second shafts are separated by a distance which can be varied A cylinder has a first end connected to the frame assembly and a rod end attached to the sliding sheave assembly. The cylinder rod end is capable of moving longitudinally relative to the first end to hereby alter the distance between the first and second shafts. A cable having first and second ends attached to the frame assembly is reeved between the pluralities of first and second sheaves.
