Point it at a well database, set decline parameters, and get a valuation and a map in chat. Its own README says Claude plays reservoir engineer and the server is the calculator, so the decline curve is still a judgment call.
For A&D analysts and reservoir engineers: get a first-pass valuation in chat, then check the curve yourself.
Process engineer Scott Duncan packaged plant practice into a skill, so Claude checks its PFD against standards and a review checklist before handing it over, catching errors like an open control loop or a steam coil above the liquid level. The output is an editable SVG plus the script that made it.
For process and chemical engineers: a first draft of a conceptual PFD in minutes, to mark up like any junior engineer's work.
