Vening™ Independent Depth-Model Assurance Engine
An assessment, not a reprocessing project.
You are not buying a six-figure reprocessing contract. You are buying a pre-registered decision on whether your depth model clears measured gates — with a signed receipt either way.

The four gates
Cheapest refusal first.
Each gate answers a question that makes the next one meaningful. Any REFUSE stops the run before inversion spend.
| Gate | Question | Pass means |
|---|---|---|
| 01Instrument clearance | Is the acquisition outside the absorbing sponge? | All sponge transits at unity; headers self-consistent. |
| 02Blind-well illumination | Do withheld wells lie inside the recorded footprint? | Every blind well inside midpoint coverage. |
| 03Target depth reachable | Does the grid reach the deepest marker? | Grid bottom below deepest pick TVDSS. |
| 04Spatially blocked holdout | Can holdout shots be separated from training? | Train–holdout separation and alternation above floor. |
The floor
Every threshold sits beside a measured floor.
A requirement without a floor is a contract defect. Blind-well mistie uses a truth floor measured independently at checkshot-constrained picks — not a velocity-domain default that would read as vacuous in depth metres.
Pre-registration
Why the pass mark is frozen before we look
On our own reference survey the marker leg carried a bias of −25.69 m against an RMSE of 33.21 m, decided against a 25 m ceiling. Removing that bias — a defensible thing to do — drops the statistic to 21.04 m and turns REFUSE into PROMOTE. One analyst choice, made after seeing the number, was worth more than the inversion.
That is why criteria are pre-registered and digest-sealed before data is seen. Your team can run the measurement. Your team cannot freeze the pass mark before seeing the result, because your team is the one under drilling deadline.
What the data can support
The precision on a depth-converted volume is mostly assumed
Depth is a linear functional of a velocity column, and a surface reflection survey is far better at reflectivity than at the vertical average velocity that positions a marker. Measured on our own operator, with a perfect noise model and a perfect prior, a surface survey removes 3–6% of the depth-positioning variance. The resolution threshold is 50%.
So the interval on a depth model built from surface seismic is largely the interpreter’s prior, not a measurement. We say so, and we refuse to report a positional interval where the data cannot support one.
The receipt
Replay without our stack.
Artifacts carry bundle digests, pinned commits, and reproduce commands. Your auditor verifies signatures and re-runs the gates — not a PDF attestation.
Qualification
Is your survey eligible?
We need licensed field data with well picks and checkshots, in a region you specify. Reference runs on public benchmarks do not substitute for your acquisition geometry.
- 01Pre-stack gathers with trace headers that agree with geometry
- 02Blind-well picks with independent time–depth control where available
- 03Explicit hold on turnaround promises — eligibility is decided by gates, not sales
Scope fence
What this is not.
- Not a commitment to deliver a better image
- Not an interpretation-suite workflow
- Not a GPU reprocessing farm — contractors with thousands of GPUs already exist
- Not a confidence percentage on a slide — REFUSE and PROMOTE are the only dispositions
