When an engineer hits a hard, advanced problem on the rig — a centrifuge that won't recover barite, a flowline that keeps surging, a degasser that won't pull — this is the reference that has the answer. Each unit in the solids-control and drilling-waste circuit, with its real failure modes broken down into design, mechanical, electrical/instrumentation and operational — every fault traced from mechanism, through detection, to correction.
Slope, diameter, inspection access, flow indication, header-box capacity and distribution — the faults that cap everything downstream.
First-stage removalSizing, motion, deck angle, screens (blinding, wear, tensioning, selection), vibration, electrical and operational failures.
Combined stageHydrocyclone-over-screen unit: cone and screen interaction, barite recovery, and the faults unique to the combined stage.
Coarse hydrocyclonesCone wear, feed head and pressure, roping vs spraying, apex/vortex problems and manifold balance.
Fine hydrocyclonesBank sizing, plugging, underflow control, feed head and the fine-cut faults that load the centrifuge.
Fine-solids stageDuty selection, pond/differential/speed tuning, bearings, scroll and bowl wear, drives and protection.
Gas handlingVacuum loss, vacuum-source and internals faults, routing, and the entrained-vs-free-gas distinction.
Active systemDead zones, sand traps, compartment routing, surface volumes, settling and short-circuiting.
SuspensionSizing, impeller wear, shaft/seal/gearbox failures, dead zones and barite sag.
Transfer & feedCavitation, seal and impeller wear, alignment, motor faults and feed-stability problems.
Mixing & shearingJet/eductor wear, nozzle and throat issues, shear, dust and build/shear faults.
Fine filtrationCartridge/DE and fine-filtration faults: blinding, bypass, sizing and brine/completion-fluid handling.
Waste chainConveyors, cuttings dryers/VCD, transfer pumps, dewatering, OOC and disposal-route faults.
Some failures only show up as a pattern across the whole train. If you've worked the unit and it still isn't right, an independent evaluation looks at the system, not just the symptom.
