Reservoir engineer and Registered Professional Appraiser (RPA) with 11+ years of experience evaluating oil and gas assets, LOE cost structures, and production economics across portfolios exceeding $10B. Core expertise in LOE benchmarking, workover cost normalization, decline curve analysis, and defensible reserves-based valuations — with a specific focus on ensuring operating costs are accurately represented in tax and asset valuations to avoid inflated property assessments and systematic overpayment.

Career highlights
• Pritchard & Abbott, Inc. – Petroleum Engineer
Evaluated reservoir performance and LOE across $10B+ in oil and gas portfolios spanning tens of thousands of wells, working directly with confidential operator financials from majors (ExxonMobil, Occidental) and privates (Mewbourne, Presidio). Reviewed multi-year LOE data and identified how non-recurring workover and recompletion costs distort single-year valuations — a systematic issue that inflates assessed property values when appraisers rely solely on the most recent 12 months of reported LOE. Built and maintained defensible production forecasts, reserves assessments, and economic models used for regulatory and financial decision-making.
• Digital Petrodata – Petroleum Engineer
Built DCF valuation models and consolidated national upstream production datasets; contributed to analytics platform development prior to company’s acquisition by TGS (2015).
LOE and workover tax valuation — Incredible Value Proposal
A core and differentiating capability: operators commonly present only the most recent 12 months of LOE in tax valuation support, excluding high-impact, non-recurring workover and recompletion costs that occur on 2–3 year cycles. When those costs fall outside the reporting window, assessed values are systematically inflated. Malachi’s experience reviewing multi-year LOE across hundreds of operators enables him to identify this pattern, normalize workover costs across the full cost cycle, and support defensible, market-representative valuations that protect operators from property tax overpayment.
