A coal formation may be treated using an in situ thermal process. In certain embodiments, devices of the invention include a housing including a proximal portion and a distal portion, in which the distal portion is movable within the proximal portion, a deployment mechanism at least partially disposed within the housing, and a hollow shaft coupled to the deployment mechanism, in which the shaft is configured to hold an intraocular shunt. The terminals are releasably engageable in overlapping relation in an engagement zone. In a certain embodiment, a particular list may be selected for display by choosing the corresponding button on a widget. Each of the above steps is performed using a computer system.
