Basin Rim

Basin Rim puts you on the rig floor of a desert oilfield. Take drilling contracts for exploration, development and horizontal wells, then work every phase of the hole with your own hands.

Balance weight on bit and rotary speed to keep the drill string out of the red zone. Tune mud density and viscosity when kick and lost circulation alarms hit. Time your connections, steer the casing to center, pump cement at the right rate, then read the sonic bond log to learn what the well is really worth.

Your payout equals contract pay times hole gauge rate times cement quality, so smooth hands earn more. Spend coins in the equipment shop on six real upgrades: a top drive that steadies drilling, an auto mud mixer that widens the safe window, a BOP stack that saves a well from blowout, an MWD tool that shows live inclination, a faster PDC bit, and a long term contract that boosts every payout.

Six hands-on stages per well, rotating contracts, persistent upgrades, custom dialogs and fully synthesized rig sounds. Spud in and keep the basin rim safe.
