Abstract

See full text

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.
