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.

Modular mobile drilling system and method of use

There is provided a portable drilling module that is preferably mounted onto a self-propelled carrier. Winterizing panels enclose equipment mounted aboard the module and provide an environmentally sheltered space for workmen. In particular, the panels fully surround a rear portion of the module that is adapted to be positioned over a well, and allow a full load of pipe to be temporarily stored within this portion of the module. Moreover, a number of the panels may be removed to reduce the weight of the module so that it can be transported and used for workover operations in warmer months.

Self-propelled drilling module

A method and apparatus is presented for facilitating the installation of electrical cables in sub-zero temperatures by heating the cables to make them more flexible and easier to work with. The cables and the workers thereon are sheltered from the elements to enhance the safety of the workers and improve the useful operating life of the equipment.

Harness method for use in cold weather oil field operations and apparatus

A fully articulating ramp extension provides a quick and efficient means of coupling a drilling module with a pipe shelter.

Fully articulating ramp extension for pipe handling apparatus

A modular drilling apparatus having three units, each of which is fully enclosed, transportable and positionable for workover and completion of wells on 30 foot well centers without interfering with the operation of adjacent wells. The first end of the drilling unit is positioned over a well with its central axis diagonal to the centerline of the wells and at a right angle to the pipe handler in the pipe shelter unit, the vertex of the right angle being at the well center. The mud unit is set back from the centerline of the wells, and is functionally connected to the second end of the drilling unit. The width of the drilling unit is greater than 50% of the clearance between adjacent well houses on each side of the well.

Mobile drilling rig for closely spaced well centers

A portable drilling apparatus 10 designed to be used in environmentally severe locations, such as the Arctic, includes provisions for heating various portions thereof, including a pipe shelter 14. The pipe shelter 14 is used to store, warm, and clean the drill pipe and/or casing prior to insertion in the well. Thus, to provide access for loading the drill pipe and/or casing into the pipe shelter 14, a significantly large opening must be provided. The large opening necessarily results in significant infiltration of arctic air and loss of heated air, thereby increasing the difficulty of maintaining the pipe shelter 14 at a comfortable working temperature. Accordingly, a high-speed spool or window-shade style door 38 is employed to seal the opening against large scale transfers of heated and cold air. Further, an indirect fired air-heater 90 having a capacity sufficient to maintain a positive pressure in the pipe shelter 14 is also used. The positive pressure within the pipe shelter 14 causes warm air to exit rapidly when the door 38 is opened, and thereby reduces the inflow of arctic air. Accordingly, the combination of the high-speed door 38 and positive pressure environment within the pipe shelter 14 combine to provide a relatively stable and comfortable temperature environment.
