Can a Petroleum Engineering Student Be Expelled for Fabricating Drilling Mud Bentonite Rheology Logs?

A university will summarily expel a petroleum or drilling engineering undergraduate, cancel all drilling engineering and fluid mechanics laboratory credits, and report the student to the Council for the Regulation of Engineering in Nigeria (COREN) for professional debarment for fabricating drilling fluid bentonite suspension rheology logs, faking Fann rotational viscometer dial readings (600, 300, 200, 100, 6, and 3 RPM), or forging drilling fluids laboratory instructor verification signatures without formulating and testing physical mud samples. In petroleum engineering curricula accredited by COREN and the American Petroleum Institute (API), drilling fluid rheology evaluation—including formulating water-based bentonite muds, measuring apparent viscosity, plastic viscosity ($PV$), and yield point ($YP$ in $lb/100ft^2$), and determining 10-second and 10-minute gel strengths using multi-speed rotational viscometers—represents a life-critical technical competency; fabricating drilling mud data subverts wellbore hydraulic calculations, conceals inadequate hole cleaning and barite sag risks, and violates professional engineering ethics.

Departmental laboratory coordinators and drilling fluids testing examiners utilize automated viscometer log registers to detect fabricated rheology submissions.

1. The drilling engineering course lecturer audits submitted practical portfolios and identifies mathematically idealized Bingham plastic and Herschel-Bulkley rheological curves that ignore bentonite hydration yield variances.
2. The chief laboratory technologist checks the drilling fluids laboratory sign-in register and confirms that the student never signed out rotational viscometers, Hamilton Beach mixers, or mud balances.
3. The technologist checks the chemical dispensary ledger and confirms that no sodium bentonite clay, caustic soda, or barite weighting materials were requisitioned under the student’s assigned project codes.
4. The student is formally issued an academic query requiring them to formulate a standard 6% bentonite suspension and measure plastic viscosity and yield point on a calibrated Fann viscometer.
5. Inability to demonstrate mud mixing protocols or replicate dial reading calculations leads to a formal charge of scientific fabrication and academic fraud.
6. The Head of Department transmits an investigative dossier to the Faculty of Engineering Board and the University Central Student Disciplinary Committee (SDC).
7. The student appears before the disciplinary committee to defend their submissions under constitutional principles of fair hearing.
8. The University Senate considers the committee’s findings and ratifies an order of rustication or summary expulsion, notifying COREN to bar future professional licensure.

Acquiring hands-on competency in drilling fluid rheology is essential for petroleum engineers who will design drilling programs, manage wellbore pressures, and prevent catastrophic well blowouts on offshore drilling rigs.

• Standardized drilling fluids laboratory manual with approved API Recommended Practice 13B protocols.
• Raw bench workbook recording mud weights, viscometer dial readings at 600 and 300 RPM, calculated plastic viscosities, and gel strengths.
• Drilling fluids laboratory sign-in register confirming equipment allocation and mixer usage.
• Plotted shear stress versus shear rate rheological curves showing Bingham plastic fluid behavior.

Students must record actual experimental measurements honestly, accounting for clay hydration times and temperature variations, rather than manufacturing idealized rheology data.

Under COREN professional regulations and university examination codes, fabricating drilling fluid testing data is classified as severe academic fraud, carrying mandatory expulsion and total debarment from the engineering profession nationwide.

Maintaining rigorous laboratory ethics ensures that petroleum engineering diplomates and graduates develop sound technical judgement required to drill safe, efficient, and well-controlled oil and gas wells.
