Abstract

An improved well mast structure and method for building the well mast structure in the form of multiple, separately attachable sections including a bottom section, a lower section, a middle section, a top section and a crown section. A bottom section having a generally U-shaped box frame at its upper end is raised to a vertical position and a separate crown section is inserted into the open end of the U-shaped box frame and placed on top of the bottom section. The top, middle and lower sections are then installed using a similar procedure. Each section is lifted by a conventional crane until its upper end is pivotally attached to the lower end of the previously installed section. The section is then pivotally lowered to a vertical position within the bottom section and pivotally raised and secured to the previously installed section. The installed sections are then raised in a telescoping manner.
