## Questions

### What does Stage 3 Separation actually do on a customer site?

Stage 3 mobilizes centrifuges, shaker systems, and filter presses to a client's location, then operates them as a closed-loop processing utility. On a drilling rig, its technicians receive returning mud, strip out drilled solids, and send reconditioned fluid back to the mud pits — reducing water purchases and disposal hauls. On a construction or tunneling project, the team devaters slurry and thickens solids for landfill or reuse.

### How does Stage 3's environmental line split from its energy-services work?

Stage 3's energy-services division focuses on drilling, completions, and mud-plant work for upstream oil and gas. Its environmental division tackles non-petroleum projects — construction slurry, pipeline crossings, tunnel-dewatering, and biosolids-lagoon remediation. Both divisions use the same underlying separation technology but operate under separate project scopes, safety plans, and client-approval chains.

### Does Stage 3 separate itself from standard oilfield-rental companies?

Rather than renting iron and walking away, Stage 3 positions itself as a fully staffed fluids-management partner. It begins each engagement with an engineering analysis of the project's fluid volume, solids loading, and disposal constraints, then assembles a customized flowsheet. Its personnel stay on-site, run the equipment, and optimize polymer dosing and throughput continuously — a service model closer to contract operations than equipment rental.

### What is the MudCube system that Stage 3 has installed in the Midland Basin?

MudCube is a vacuum-based solids-separation technology that replaces conventional vibrating shakers with an enclosed rotating filter belt. A high-volume air stream lifts drilling fluid through the screen, trapping solids on the belt and discharging clean fluid. The enclosed design reduces vapor emissions and noise while improving separation efficiency, and Stage 3 has trialed it on Permian wells.
