Abstract

A modular mobile drilling system and method of use supports land-based drilling operations on remote sites. Plural support boxes fixedly deployed in first and second rows define a drilling zone. A plurality of platform support beams disposed from the first row to the second row support a platform for holding drilling equipment. An actuator associated with the platform and beams skids the support beams relative to the boxes to align the platform with predetermined positions in the drilling zone, allowing the drilling of multiple wells along the length of the support box rows. The drilling equipment can also skid laterally across the drilling platform to support drilling of multiple rows of wells in the drilling zone. The drilling platform is supported by some but not all of the support boxes, enabling modular transportation by helicopter of support boxes to a new remote drilling site, disassembly of the drilling platform at the existing site, reassembly of the drilling platform on the transported boxes at the new site, and then transportation of remaining boxes from the existing site to the new site to support new drilling operations. The box-on-box substructure and skiddable drilling platform enhance transportability by helicopter and assembly with minimal footprint and reduced assembly steps.
