Twenty-seven invitations.
First in,
first to gain.
Hand-picked companies across drilling, completion, production and offshore. Each one strengthens what the next licensee sees. If your company is on the list below, you've already received a cover letter. If not, the contact page is the way in.
Three things that go to the early signers.
The $30k introductory price
Locked at signing for Year 1. Renewal priced in writing before you have to decide.
The first marketplace seat in your lane
Failure modes you spot first become signed assets you can trade. Only the first thirty open a seat.
Reference-customer publishing rights
The first OFC licensee to publish a case study lifts close rates 15–20% for everyone in the network — including future-you, on new chains.
PHASE 1 · OilfieldChain · 9 invited
Completion · frac · stimulation · wireline · 6 expected closes
Wave 1: Lime Instruments · Pason Systems · NCS Multistage · Cudd/RPC · Stress Engineering Services · Seismos · Rapidlogger Systems · DarkVision Technologies · Premium Oilfield Technologies
PHASE 2 · DrillChain · 7 invited
Drilling · rig · MWD/LWD · surface systems · 5 expected closes
Wave 1: Patterson-UTI Energy · Nabors Industries · Precision Drilling · Scientific Drilling International · Pason Systems (cross-phase) · Corva · Drilling Tools International
Dropped from Wave 1: H&P (owns MagVAR — structural conflict), Newpark (post-divestiture identity unclear)
PHASE 3 · ProductionChain · 5 invited
Artificial lift · rod · ESP · gas · plunger · 4 expected closes
Wave 1: Flowco · Weatherford Production Intelligence (PRI) · Borets International (US + EU subsidiaries) · Tally Energy Services · Cactus Inc.
Lane has been gutted by SLB consolidation. Smaller Wave-1 invite list is intentional. Operator-direct lane (Pioneer / EOG / Devon shape) is the Wave-2 fallback if Tier 3 is thin.
PHASE 4 · OffshoreChain · 6 invited
Offshore + subsea · floaters · trees · ROV ops · 5 expected closes
Wave 1: TechnipFMC · Noble Corporation · Oceaneering International · Helix Energy Solutions · Expro Group · Innovex International
Dropped from Wave 1: Transocean (Valaris merger renegotiation risk), Subsea7 (Saipem merger), Aker (SLB-JV complication via OneSubsea). All three move to Wave 2 post-consolidation. Founding-seat holders are protected when they re-enter.
WAVE 2 · deferred invites
Five candidates deferred to Wave 2 across the four lanes. Re-invited as consolidation, merger, and identity-resolution events resolve. Wave-2 closes could add another $1.5–$2M ARR at maturity on top of the Wave-1 base.
