Where Decline-Curve Analysis Fits — and Why We Built a Browser-Native Engine for It
Decline-curve analysis is the load-bearing first step of almost every reserves number. We rebuilt the hard part to run entirely in the browser — matching Equinor's open-source math to 0.02 ppm, with no server and no data upload.

The open-source reservoir engineering stack — reference architecture for the bottom of the market
Three modules, sharing a Postgres backbone: ingestion, model/forecast, reporting+audit. Buildable in 4-8 weeks on $40-80/month infrastructure. The open-source replacement for the enterprise reserves stack at the bottom of the market.
What super-majors actually built — Johan Sverdrup and SLB's agentic AI reservoir architecture
Two recent reference architectures from the published literature: Equinor's Johan Sverdrup digital twin and SLB+ONGC's 2025 agentic AI framework for large-scale well modeling. Both describe the same architectural pattern.
The reserves engineering gap — three workflow gaps the 2024-26 literature is calling out
Small E&P operators and family offices are running 2026 capital on 1990s workflows. The 2024-26 reservoir engineering literature has converged on the diagnosis: the gap is in workflow infrastructure, not algorithms.

Mineral royalty cash flow to PV-10 — the valuation modeling step
Stage 5 of the Texas mineral valuation pipeline: the four inputs (Arps decline, price deck, lease economics, discount rate), the monthly cash-flow math, and the 13-line validation checklist that catches the recurring NPV errors.
Texas decimal interest math — pooled vs allocation walkthrough
Same well, two methods, 32% gap. The math behind why allocation-well decimal interest differs from pooled approximation, with a worked example and the PostGIS geospatial step that makes the answer defensible.
Surface parcels to net mineral acres — the data layer every Texas mineral valuation depends on
Stages 1 and 2 of a defensible Texas mineral valuation: acreage technique (43,560 sq ft, geodesic projection, source tiering) and ownership resolution (severed estates, UMI math, the 3/8 example). With an 8-line audit checklist.
Why pooled math fails Texas mineral valuation — the allocation well story
Texas RRC has issued ~5,000 allocation well permits since 2022 vs ~600 PSA permits. Generic mineral calculators built for forced-pooling states get this wrong by 30%+. The legal story, the math gap, and what to do about it.
How oil & gas mineral royalties actually pay — and where the headline numbers quietly inflate
$600K in year one, $250K in year two, $20K by year ten — and roughly $1.35M cumulative across a decade. A line-by-line walkthrough of how an oil & gas royalty actually pays from first principles, with the seven things that take 20-40% off the headline.
