Rock generated is not rock received.
Formation volume, transport, arrival time and particle change. Match the drilling interval to what reaches the surface before comparing records.

FROM FORMATION
TO WASTE
A practical framework for drilled-solids control, drilling-fluid control and waste performance.
Where did the drilled solids go, and what did it cost to manage them?
Follow the material from formation to its actual destination. Put the records on the same clock. Then test the explanation before changing the system.

Why I wrote it
A stable mud report is only part of the picture.
A mud report can look stable while the system is working harder and costing more. Make-up, discard, retained solids and waste can move in the wrong direction without one property telling the whole story.
“So I do not start by blaming a machine. I trace the material first, then test the explanation.”
This framework connects Solids Control, Drilling Fluids Control and Drilling Waste Management through one operating window. It helps the team explain what the records show, what they do not show, and what needs to be measured next.
Inside the framework
From the first solids estimate to the field decision
The Mud Report Blind Spot
Retort interpretation, solids estimates and the Conditional Dilution Trap. Three dilution models show why the assumptions change the answer.
Test the actual equipment duty.
PSD, separation curves, matched sampling and device balances. Use equipment calculations as checks; do not substitute a nameplate for field evidence.
Keep the ledgers separate.
Dry-solids mass and fluid volume, SRE, SREopt and MCR. Worked examples make the measurement basis, assumptions and uncertainty visible.
Follow every discharge.
Recovery boundaries, waste routes, retained-fluid reporting and costs. Regulatory examples keep the method and reporting basis beside the number.
Write down the next decision.
Protocols A–E, an audit checklist, workshop exercises and blank sampling and decision records. Record who acts, what stops the test and when to check back.
Go deeper: The solids-control mass balance · Solids-control cost per foot · Technical training. The full workbook includes the method, assumptions, limits, and records to test it against an operating interval.
A practical starting point
Take one operating window. Make it traceable.
Start with the actual route, including bypasses and discharge destinations. Keep raw readings and their units. Compare samples only when their timing and basis are compatible.
If the evidence is incomplete, the useful result is a specific measurement request. One number should start an investigation, not trigger a machine change.
Discuss a rig evaluationThe field sequence
- Define the interval and system boundary.
- Verify the route and measurement basis.
- Match arrival, sampling and reporting time.
- Reconcile inputs, outputs and inventory.
- Test the competing explanations.
- Measure what could change the answer.
- Record the action and check the result.
Who it is for
Solids-control engineers, mud engineers, drilling engineers, supervisors, drilling-waste teams, technical support personnel and instructors who need to connect equipment observations with system performance.
The framework is an engineering evaluation method. It does not replace controlled standards, OEM instructions, site procedures or permits. Worked values are hypothetical unless identified otherwise; composite scenarios are teaching patterns, not records from a named rig. It has undergone internal technical review, not independent peer review.
Put the method to work
Read it. Discuss it. Apply it to your operation.
Training
Use the balances, sampling records and worked cases in an agreed classroom, workshop or rig-based program.
Rig evaluation & support
Review actual routes, equipment duties, fluid losses and waste records. Identify the evidence needed before recommending a change.

Before you use it
Is the PDF free?
Yes. The complete V1.1 PDF is free. Enter your email on this page to unlock the download. Edition and training updates are optional and off by default.
Does it give universal equipment settings?
No. Equipment duty, fluid, feed conditions and site limits matter. The method helps you establish the basis for a decision rather than copy a setting from another operation.
Can we use it for a company training program?
Contact SC DrillTech to discuss participants, equipment, practical access and learning objectives. Instructor-led delivery and any licence to reuse training materials are agreed separately.
Is the framework already built into Rig IQ?
This page links to Rig IQ for related engineering work. It does not claim that a complete Formation-to-Waste workflow is currently implemented.
