Abstract
A drill string connect tool comprises a housing having first and second sections. The first section has a first recess, and the second section has a second recess. The tool and the first and sections may be in a connected configuration or a disconnected configuration. The connect tool comprises at least one tension member placeable within, and suitable to transfer tensile forces between, the first and second sections when in the connected configuration. A retaining member can retain the tension member within the first and second recesses. The retaining member is selectively dissolvable by a dissolving fluid, while the remaining components of the tool can withstand the dissolving fluid. When exposed to a dissolving fluid, the retaining member dissolves, allowing the tension member to exit the first and second recesses, thereby actuating the tool to the disconnected configuration.
