Buy the gravity & magnetics survey to reveal the basin's depth structure and the mature source-rock kitchen (green = oil window, red = gas window). Hydrocarbons migrate out of the kitchen — traps close to it are better charged.
Shoot 2D seismic: click “Plan 2D seismic” and drag a rectangle over the map. Mapped closures become leads. Subtle stratigraphic traps are often missed; anticlines are easy.
Keyboard users can enter start/end X/Y coordinates and commission a 2D survey with the controls below the map.
Mature leads with 3D seismic. This tightens the size range (P90/P50/P10 prospective resources), confirms or condemns the trap, and may reveal DHIs (flat spots) that de-risk charge — turning a lead into a prospect.
Drill wildcats on the best prospects. Success chance = GCoS (source × reservoir × trap × seal × charge). Dry holes tell you which element failed and re-risk the whole play — information is never wasted.
Appraise discoveries to narrow contingent resources (1C/2C/3C), then take FID to book reserves (1P/2P/3P) and develop a field. Production ramps, plateaus and declines; revenue repays project debt first.
Trade: accept farm-in offers from competitors or divest any asset at a market bid. Grow company value without going insolvent.
PRMS terminology: play → lead → prospect → discovery → field; Prospective → Contingent → Reserves → Production. See docs/ for full documentation. Add ?seed=123 to the URL for a different basin.
