A drilling contractor in the Permian can have the safest crews in the basin and still lose a contract to paperwork. If your ISNetworld grade slips to a C, your Avetta flag turns red, or your Veriforce profile lapses, the operator's procurement system removes you from the approved vendor list and the work orders stop. No meeting, no phone call, no appeal to the company man who knows your crews are solid.
Prequalification is where safety documentation becomes revenue protection. This guide is the hub for everything BasinCheck has published on the subject: how the three major platforms differ, the documentation stack they all evaluate, the scores that decide eligibility, and a 90-day plan to get your records defensible before the next review cycle.
What prequalification is and why operators require it
Contractor prequalification is the verification step between "we'd like to hire you" and a signed Master Service Agreement. Operators face real liability for contractor incidents on their sites under OSHA's multi-employer worksite doctrine, and their insurers and legal teams require proof that every contractor on location meets defined safety standards. Rather than audit hundreds of contractors themselves, most operators outsource verification to a third-party platform and make an approved profile a contractual condition of eligibility.
That structure has a consequence contractors feel every day: the platform's reviewers, not the operator's field staff, decide whether your documentation passes. Reviewers never see your crews work. They see your uploaded insurance certificates, written programs, OSHA logs, and questionnaire answers. Contractors who fail prequalification almost never fail on safety performance. They fail on records that don't hold up to review: generic program language, logs that don't reconcile, training tracked at the company level instead of by employee.
ISNetworld vs Avetta vs Veriforce
Three platforms control most contractor prequalification in U.S. oil and gas. You don't choose between them — your operators choose for you, and many oilfield contractors end up maintaining profiles on two or all three.
| Comparison area | ISNetworld | Avetta | Veriforce |
|---|---|---|---|
| Where it dominates | General oil & gas, construction, utilities — the broadest operator base | Mixed industrials; modular per-client requirements | Pipeline operators and DOT-regulated work |
| Scoring model | Letter grades (A–F) per hiring client, RAVS + TRIR weighted | Traffic-light flags (green / amber / red) per client | Per-operator thresholds on TRIR, EMR, and documentation |
| Program review | RAVS review of written safety programs | Safety Manual Audit with proof of implementation | Document review plus operator questionnaires |
| Training layer | Operator-specific requirements | Client-configured requirements | PEC Safety Training and individual OQ records |
Where to go deeper on each platform
Each platform has enough platform-specific traps to deserve its own guide. For ISNetworld, start with what ISNetworld is and how ISNetworld data standardization keeps your RAVS submissions consistent; the score simulator shows your realistic path to an A grade and the cost estimator sizes the subscription before you commit. For the other two platforms, see how to pass Veriforce safety qualification and how to pass Avetta qualification.
Founder-led setup
One documentation system. Every prequalification portal.
Bring your current safety programs, OSHA logs, or portal requirements. We will map them to BasinCheck and show how one crew's daily documentation feeds ISNetworld, Avetta, and Veriforce reviews at the same time.
The documentation stack every platform checks
Strip away the platform-specific packaging and all three services evaluate the same six categories. Get these right once, in one system, and every portal submission becomes an export instead of a scramble.
Insurance certificates
Current COIs for General Liability, Workers' Comp, Commercial Auto, and Umbrella. Limits are set per operator; $1–5M GL per occurrence is common in oil and gas.
Written safety programs
Procedure-level programs for your trade: HazCom, LOTO, Confined Space, Fall Protection, H2S. Generic template language fails review on every platform.
Incident history
Three years of OSHA 300 and 300A logs that reconcile with the TRIR you report. Reviewers cross-check the numbers; mismatches stall qualification.
EMR documentation
An EMR letter issued by your insurance carrier, not a broker summary. Most operators want to see 1.0 or lower, with explanations for any spike.
Training records
Completions tracked by individual employee, task, and date: SafeLand/PEC-style orientations, OQ where pipeline work applies, and H2S where required.
Questionnaire answers
MSQ/PQF responses that match the documents you upload. Inconsistencies between answers and evidence are one of the most common review flags.
Written programs are where most contractors fail
A safety manual that says "we comply with all applicable OSHA standards" fails review on every platform. Reviewers look for procedure-level specificity: named responsible parties, inspection frequencies, step-by-step procedures for the hazardous tasks your crews actually perform. The RAVS Gap Analyzer checks your programs against the categories ISNetworld reviews, and the free prequalification toolkit includes written program templates for LOTO, HazCom, fall protection, and H2S built for oilfield trades.
Records have to reconcile with each other
Platforms cross-check. The TRIR you report has to match your OSHA 300 log. Your questionnaire answers have to match your uploaded programs. Your training claims have to match individual completion records. Every mismatch triggers a corrective cycle — a rejection, a fix, a resubmission, and another review wait. Contractors who keep the records operators require current all year clear reviews in one pass.
The scores that decide eligibility
Whatever the platform calls its grade, the inputs are the same three lagging indicators — and they follow you for three years.
TRIR, EMR, and DART
Most operators in oil and gas set a threshold of 1.0 or lower for both TRIR and EMR, with DART reviewed alongside them and benchmarked against BLS averages for your NAICS code. The exact cutoffs are set per operator, and being over threshold isn't always fatal — many operators accept a documented corrective action plan in place of a clean number. What is fatal is a high rate with no explanation and no documented response.
The three-year window
Every platform scores on a rolling multi-year average, typically three years. A single recordable in 2024 affects your grade until 2027. That math cuts both ways: you can't fix this quarter's grade this quarter, but every quarter of clean, well-documented operation is banked. It also means short-service employee programs matter — operators like Chevron track SSE ratios precisely because new hands drive recordables.
Beyond the portals: operator-side audits
Clearing ISNetworld, Avetta, or Veriforce gets you onto the approved vendor list. Staying there means passing the operator's own layer of verification: contractor HES management programs like Chevron's CHESM, field verification visits where an operator rep checks that the JSAs and inspections in your portal profile actually happen on location, and annual document requests before MSA renewals. Our Chevron & ConocoPhillips audit guide covers the 100-point CHESM scale and what field verifiers pull.
This is the layer where paper systems break. A portal profile can be polished once a year by an office manager. A field verification audit checks whether the daily documentation operators expect — JSAs with real signatures, timestamped inspections, photo evidence, closed corrective actions — exists for last Tuesday, not just for audit week. Contractors running digital safety audits pass this layer because the records generate themselves as crews work.
The 90-day readiness plan
Ninety days is a realistic window to go from scattered records to a defensible submission on any platform — if the work is sequenced instead of crammed into the week before a review.
Days 1–30: Find the gaps
- List every operator you work for (or want to) and which platform each one uses
- Run your written programs through the RAVS Gap Analyzer against your trade's requirements
- Pull three years of OSHA 300/300A logs and calculate your actual TRIR
- Request a current EMR letter from your insurance carrier
Days 31–60: Fix the record
- Rewrite generic safety programs with procedure-level detail and named responsible parties
- Reconcile OSHA logs with the incident rates you plan to report
- Rebuild training records by individual employee, task, and completion date
- Document corrective action plans for any recordable that pushed TRIR above 1.0
Days 61–90: Submit and monitor
- Submit to the platform your highest-value operator requires first
- Answer questionnaires task-specifically and consistently with uploaded evidence
- Set renewal tracking for every certificate, program review date, and training expiration
- Keep field documentation flowing so next year's submission is an export, not a project
The pattern behind every phase is the same: contractors who treat prequalification as an annual project stay in the corrective cycle, and contractors who treat daily field documentation as the source of record clear reviews in one pass. That's the system BasinCheck is built to run — audits, JSAs, corrective actions, and training records that stay export-ready for whichever portal asks next.
