Rig Solids Control & Mud System Evaluation
A complete, independent health-check of the rig's solids-control and mud system — the equipment, the settings, the cut points and the cost. You get a clear picture of how the system is really performing and exactly what to change, ranked by impact. This is the door most engagements start from.

Two ways we run it
Remote evaluation Off-site
Built entirely from your data — daily solids-control reports, mud checks, rig hydraulics, centrifuge and screen logs and the fluids program. Fast, low-cost, and needs nobody on the rig.
- Performance review and root-cause analysis on what the numbers actually show
- Dilution, barite and low-gravity-solids trends rebuilt from the reports
- Ranked corrective actions and equipment settings to change
It answers most "why is dilution, barite or torque so high" questions without a flight or a day rate — but it can only work with what can be reported. Anything that needs a physical reading on the equipment waits for the rig.
On-site evaluation On the rig
An engineer on the rig with instruments, taking the measurements no report can give you — first among them the shaker G-force test.
- Shaker G-force test — an accelerometer on the basket reads the actual G-factor and motion the deck is developing
- Vibratory-system analysis — linear vs elliptical motion, stroke, exciter synchronisation, out-of-balance, bearing and vibrator health
- Live sampling, screen and cut-point verification, and a full walk-down of the solids-control and mud system
This is where assumptions become measured fact — and where the fixes a remote review can only suspect get confirmed and quantified.
Why the G-force test is on-site only. A shaker's nameplate promises one G-factor; what the basket is really developing after months of service — worn motor bearings, mismatched or shifted counterweights, a soft or cracked deck mount, wrong vibrator timing — is almost always different, and it drives conveyance, screen life and how dry the cuttings leave the deck. The only way to know the real number is to put an accelerometer on the deck and measure it. That is why the G-force and vibration work sits firmly in the on-site scope: it cannot be done from a report.
The deliverable is a decision package — baseline, findings, prioritised actions and the cost they move — not a 50-page report you'll never act on.
What we measure
- Shaker G-force & motion on-site — the actual G-factor on the basket against design and what the screen and cut point need.
- Vibratory system condition on-site — motion type, stroke, frequency, exciter sync, out-of-balance, bearing and vibrator health.
- Conveyance & screen performance — how G-force and motion translate into conveyance, screen life and dryness across the deck.
- System health — removal efficiency, LGS load, equipment cut points, centrifuge KPIs and PSD across the train.

Performance Optimization
The problem
Your system runs, but dilution and barite spend are high, screens don't last, and the centrifuge isn't earning its place.
What you get
- A measured baseline of removal efficiency, LGS load and equipment cut points
- Specific, equipment-by-equipment settings and screen/cut-point changes
- A prioritised action list — what to change first, and why
Outcome: lower dilution and barite cost and a cleaner system — without buying new equipment.
Request this →Root Cause Analysis (RCA)
The problem
A chronic, recurring problem — high torque, wet cake, screen blinding, roping — that keeps coming back no matter what's tried.
What you get
- Structured root-cause investigation against the data, not guesswork
- The actual mechanism behind the failure, isolated and explained
- Corrective actions that fix the cause, not the symptom
Outcome: a recurring failure resolved at the root — and a rig that stops losing time to it.
Request this →Cost Reduction Assessment
The problem
Mud, barite and waste-disposal costs are climbing and nobody can point to exactly where the barrels and dollars are going.
What you get
- A line-by-line view of where dilution, barite and disposal cost is generated
- The high-impact savings, ranked by size and ease
- A clear before/after case you can put in front of management
Outcome: a costed savings plan tied to dilution, barite and disposal — decisions, not a report.
Request this →Independent Technical Assessment
The problem
You're reviewing a tender, a vendor claim, or a package acceptance — and you need a verdict that isn't coming from the people selling it.
What you get
- Vendor-neutral review of equipment, tender or package against what it must actually do
- Claims checked against API RP 13C and real field performance
- A plain verdict: accept, reject, or what to change before you sign
Outcome: an independent engineering verdict that protects the spend before it's committed.

Drilling Waste Management Assessment
Most reviews stop at the cuttings dryer. A real DWM assessment looks at the whole waste chain — how cuttings are collected, conveyed, stored, transferred off the rig and finally disposed of — because that is where the hidden cost, the HSE exposure and the compliance risk actually sit. Few specialists cover it end-to-end; it is one of SC DrillTech's clearest advantages.
What we assess across the waste chain
- Collection & conveyance — screw conveyors and augers off the shakers, mud cleaner, centrifuge and dryer: wear, flight damage, jamming and liquid backflow on inclined runs.
- Cuttings transfer pumps — hydraulic S-valve pumps that move high-solids, abrasive cuttings over long distance and feed the dryer without backflow: capacity, line and hose wear, and whether they're the right call versus a screw conveyor.
- Vacuum units — air-driven vacuum systems for tank bottoms, sumps, spills and viscous sludge: lift, duty cycle and where they belong in the layout.
- Storage & transfer tanks (CSTs) — cuttings storage and transfer capacity at source, and whether it's throttling drilling speed.
- Drying & dewatering — vertical cuttings dryer and high-G drying shaker recovery and discharge dryness, plus dewatering-unit performance on fine (sub-5-micron) solids.
- Oil on cuttings (OOC) — retained oil on the discharged cuttings, measured by retort against the discharge limit that applies to your region: the single number that decides whether the waste can be discharged, must be treated further, or has to go to shore — and the one that drives both compliance and disposal cost.
Disposal routes we evaluate
- Skip & ship — skip filling, crane lifts, vessel logistics and weather windows: the simple route, but the one most exposed to deck space, lifting risk and downtime.
- Bulk transfer — pumping cuttings from rig CSTs to vessel CSTs: fewer crane lifts, faster turnaround and lower HSE exposure than skips.
- Cuttings re-injection (CRI) — where annular injection is viable, and what it takes to run it safely.
- At-source thermal (TCC / TDU) — rig-based thermal desorption that recovers base oil and cuts transport: where it pays, and where it doesn't.
Why this is the edge. Oil-on-cuttings limits, disposal cost and vessel logistics are where DWM quietly bleeds money and risk. An independent assessment of the full chain — not just the dryer — routinely surfaces savings and compliance gaps the equipment vendors never raise.

How we work
Desktop & data reviewWe start from your reports, rig data and fluid program — the picture before anyone steps on the rig.
Remote or on-site assessmentRemote troubleshooting and performance review, or a focused site visit and sampling where the question needs it.
The decision packageYou get the verdict, the ranked actions and the cost they move — written to be acted on, not filed.
What you walk away with
- A measured baseline of how the system performs today — fact, not opinion.
- Findings ranked by impact and by the cost they move.
- Specific settings and equipment changes — what to do, and in what order.
- The cost each change moves: dilution, barite, waste disposal and equipment spend.
- A short executive summary you can put straight in front of management.
- Performance analysis reports, OOC & ROC — oil-on-cuttings and return-on-cost figures that put a compliance and a money number on every recommended change, so the decision is justified, not asserted.
Independent by design
SC DrillTech sells judgement, not equipment. There is no package to push and no vendor to protect, so the recommendation is the one your rig actually needs. Every engagement is handled confidentially, and the work draws on 26+ years of solids-control and drilling-waste experience across the GCC, MENA and beyond.
Common questions
Do you have to be on the rig?
No. Most evaluations start remotely from your reports and data. Only physical measurements — chiefly the shaker G-force and vibration test — need an on-site visit.
What exactly is the shaker G-force test?
An accelerometer placed on the shaker basket measures the actual G-factor and motion the deck is developing against its design. No report can show it, which is why it is done on-site.
Are you independent from equipment vendors?
Yes. SC DrillTech sells engineering judgement, not equipment. There is no package to push, so the recommendation is the one your rig actually needs.
Is our data kept confidential?
Yes. Every engagement is handled in strict confidence. Nothing is shared or attributed to you.
What do we actually receive?
