Numeric Solutions provides every element required to acquire, permit, develop, operate, and retire a hydrocarbon asset—subsurface interpretation, reservoir and drilling engineering, UIC and agency permitting, field operations, compliance, and the accounting behind it. One firm, senior practitioners, from prospect to plugging. Founded in Ventura, California in 1999.
Most operators buy these disciplines from four or five vendors and spend their own time stitching the answers together. Numeric carries them as one team—so the geologic model, the injection pressure, the permit narrative, the AFE, and the monthly production report all agree with each other.
Subsurface mapping, structural and stratigraphic interpretation, petrophysics and formation evaluation, seismic interpretation, prospect generation, and 3D geocellular modeling built for handoff to simulation.
Reservoir simulation, material balance, decline-curve analysis and type curves, waterflood and thermal surveillance, IOR/EOR screening, and SEC- and lender-grade reserve reports with probabilistic risking.
Well planning and directional design, AFE and cost estimation, geosteering and real-time drilling support, completion and stimulation design, artificial-lift optimization, and recompletion candidate selection.
P&A planning, sequencing, and cost estimation; asset retirement obligation and idle-well liability modeling; wellbore integrity and zonal-isolation review; and certified risk assessments supporting surface development over legacy wells.
Class II project applications and project-by-project reviews, AOR/ZEI determination, MASP and injection-pressure modeling, aquifer exemptions, and Class I and Class VI application authorship. 60+ California projects.
CalGEM, Regional and State Water Boards, EPA, air districts, TXRRC, and county/city land use. Permit strategy, NOI and land-use applications, CEQA support, NOV and deficiency response, and agency negotiation.
Day-to-day operations management for working-interest owners—pumper and contractor supervision, production surveillance, workover and repair execution, facility and tank compliance, and agency inspections.
Monthly joint-interest billing, revenue distribution, royalty and NPI calculation and payment, accounts payable and vendor management, lease-level cash management, and owner reporting packages.
Buy- and sell-side technical and financial diligence, offering memoranda and data rooms, valuation for litigation and bankruptcy, ARO and liability quantification, and testifying and consulting expert support.
Scope is built to the asset. Below is the working inventory of what Numeric delivers—engage any one line, or the whole stack.
Defensible subsurface interpretation is the foundation everything else rests on—the reserve number, the permit, the drilling target, and the abandonment plan.
From single-well decline work to full-field simulation and third-party reserve reports built to survive lender, auditor, and courtroom scrutiny.
Thirty-five years of California operating experience on the engineering side—planning the well, costing it honestly, and being on the phone while it is drilled.
Retirement obligations are now a first-order economic driver in California. Numeric quantifies them, sequences the work, and defends the result to CalGEM and to local agencies.
Numeric's deepest specialty. 60+ California Class II projects for 25+ operators since the 2019 regulations, plus aquifer exemptions, Class I, and 15+ Class VI applications.
We read the operative regulation before we concede anything. Where an agency request is supported, we comply and cite it; where it is not, we say so and make the agency identify its authority.
The back office that keeps a small operator out of trouble: bills paid, royalty owners paid correctly and on time, and a clean monthly package the owner can actually read.
Numeric has prepared and closed transactions on both sides of the table, and has stood behind the numbers in deposition, in bankruptcy court, and in front of lenders.
Numeric acts as contract operator and asset manager on behalf of working-interest owners—end-to-end responsibility for the field, the filings, and the checkbook. That operating seat is the reason our technical work is practical: we have to live with the recommendations we write.
Numeric provides full contract operations and asset management for the Yoelin properties, a portfolio of legacy Los Angeles and Orange County oil leases. Our team runs field operations and contractor oversight, carries every CalGEM, South Coast AQMD, and sanitation-district filing, executes workovers and facility upgrades, manages accounts payable and lease-level cash, and prepares and pays the monthly royalty and net-profits distributions. The owner receives one monthly package and one point of accountability—without carrying an in-house operating staff.
Numeric has supported majors, independents, private equity, municipalities, developers, and law firms—in the Ventura, Santa Maria, San Joaquin, Salinas, and Los Angeles basins, and across Texas, the Rockies, the Gulf of Mexico, and internationally.
Most engagements begin as a single defined task. Many become a standing relationship covering the whole asset—but that is the client's decision, made after the first deliverable, not before it.
Tell us the asset, the constraint, and the deadline. We tell you what the work actually requires—including when it requires less than you expected.
A defined scope of work with deliverables, schedule, assumptions, and a fee estimate against a published rate schedule. No open-ended engagements.
Senior practitioners do the work. You get direct access to the person building the model or writing the application—not a relationship manager.
We stay with the deliverable through agency review, board presentation, lender diligence, or field execution until it lands.
Numeric is roughly thirty geoscientists, engineers, regulatory specialists, and finance professionals—most with twenty to forty years in the business, and most of that in California.

Behind the leadership group: petrophysicists and formation-evaluation specialists (Texaco, Chevron), reservoir simulation and geomodeling engineers, geophysicists (Amoco, Benton), structural geologists and geomechanics PhDs (ExxonMobil, Arco, Aera), completions and thermal-operations engineers (BP, Venoco), certified engineering geologists, civil and facilities engineers, air quality and CARB specialists, hydrogeologists, land and title professionals, GIS technicians, and technical writers—scaled onto a project only when the scope calls for them.
A permit that won't move, a reserve number you can't defend, an abandonment liability nobody has priced, or a field that needs someone to run it. Tell us the situation and we'll tell you what it takes.
