MRC DEVELOPMENT PARTNERS · DALLAS, TEXAS
Institutional-Grade Oil & Gas Investing
A disciplined approach to Texas oil and gas since 1995.
MRC Development Partners offers direct participation in oil and gas joint ventures across established Texas producing trends — from Gulf Coast salt dome structures to horizontal development in the Austin Chalk and Buda/Eagle Ford. Projects are evaluated with technical review, conservative economics, and experienced operations through our affiliated licensed operator. Backed by Magna Resources' track record since 1995, including over $100MM returned to investors across a ten-year span.

Track Record
The numbers the operator reports, not the numbers a brochure promises.
BOE means barrels of oil equivalent — the unit that lets oil and natural gas be counted together. Figures are historical. Not projections and not indicative of future results.
Where We Operate
Four entries in the register.
Each play is logged the same way: trend, approach, region, status. The same disciplined approach informs each of them.
We develop where production history and mapped geology already exist.

Track Record · The Brookshire Discovery
Others drilled the crest. We found the flank.
Magna did not discover the Brookshire Dome. The dome was long known, and the shallow crest play above 3,000 ft was opened by another operator in 1996 and drilled by six operators through the field’s early years. What Magna discovered, and developed, is the flank.
Brookshire Dome, Waller County — a discovery on a structure already drilled.
The Brookshire Dome sits in Waller County, about 35 miles west of Houston. Its shallow Miocene crest had been drilled since the late 1990s. In December 2003 Magna drilled a discovery well on the dome’s flank, opening a producing interval between roughly 3,900 and 5,000 feet that the crest operators had never targeted. In 2016 a proprietary 3-D seismic inversion extended the field again with a deeper Yegua discovery on the southeast flank.
- 01Miocene crest, shallower than about 3,000 ft · drilled from 1996 by other operators
- 02Flank discovery · Magna, December 2003 · producing interval roughly 3,900 to 5,000 ft
- 03Deeper Yegua discovery · southeast flank, July 2016 · 3-D seismic inversion
- 04Deep southeast flank imaged to 15,000 ft in the 2015–16 program · not yet tested · prospective, not a reserve and not an offering
Schematic and not to scale. Only the 2003 flank interval depth (roughly 3,900 to 5,000 ft) and the 15,000-ft limit of the imaged deep target are stated depths; the vertical position of the 2016 Yegua discovery is illustrative. Source: Magna Resources, historical highlights.

The Brookshire flank was found by studying a structure other operators considered fully drilled. The same discipline — proprietary subsurface and seismic data, careful technical review, and development inside established trends — is what the firm now applies in the Austin Chalk, on the acquired Buda/Eagle Ford wellbore, and in its New Mexico natural gas evaluation, which remains under evaluation and is not currently an offered program. Brookshire is the proof, not the plan.
The full decision trail behind the 2003 flank thesis and the 2015–16 program is set out on Method & Track Record.
Underwriting
What we look for in a project.
The factors we weigh when evaluating a project before partner capital is committed. How each applies depends on the project.
| Price assumption | CONSERVATIVE |
|---|---|
| Reserve analysis | TECHNICAL REVIEW |
| Trend selection | ESTABLISHED HISTORY |
| Operator | AFFILIATED / LICENSED TX |
| Operation model | OPERATED & NON-OP |

- 01
Technical Review
Geology, offset production and engineering data are reviewed before a project is offered. Where appropriate, we use outside engineering firms, including DeGolyer & MacNaughton on prior properties.
- 02
Downside-First Economics
We look at project economics under conservative price assumptions, not just a strong price deck.
- 03
Established Producing Trends
We develop in trends with known production history and mapped geology — salt dome structures, the Austin Chalk, the Buda and Eagle Ford. Development and exploitation over wildcat exploration.
- 04
Operational Control
Triangle Three Resources, our affiliated licensed Texas operator since 2003, manages land, legal, drilling, completion and field operations across 60+ counties and four Railroad Commission districts. Low-cost operations and direct accountability.
- 05
Multiple Points of Entry
New development, recompletion and re-entry of existing wellbores, and both operated and non-operated participation. When we can acquire a wellbore that has already been drilled, partner capital funds completion instead of drilling risk.
Corporate Structure
Sponsor, operator, and partner — under one roof.
MRCDP is not a promoter reselling someone else's deals. The same group sources, operates, and reports.
Risk Management
Downside first. Return second.
- A
Proven Reserves
Focus on developed and underdeveloped fields with established production history.
- B
Conservative Economics
Projects are tested against conservative price assumptions before commitment.
- C
Regional Depth
Three decades of Texas and Gulf Coast geology, regulatory and operating experience, across four Railroad Commission districts and 60+ counties.
- D
Operational Flexibility
Operated and non-operated prospects, providing diversified opportunities with tailored levels of operational involvement.
- E
De-risked Entry Where Available
Acquiring existing wellbores and recompletion candidates reduces the share of capital exposed to drilling risk.
Investor Benefits
Income potential, with the tax treatment of direct ownership.
Cash Flow Potential
Producing wells can generate distributions from oil and gas sales. Timing and amounts vary by project and are not guaranteed.
First-Year Tax Deductions
A meaningful share of drilling costs may be deductible in the first year through Intangible Drilling Costs (IDCs), depending on the project and your tax position.
Asset Ownership
Joint venture structure provides direct ownership interest in producing oil and gas assets.
Inflation Hedge
Hard asset exposure to commodities that historically perform well during inflationary periods.
Transparency & Reporting
Regular production and financial reporting, and direct access to the team.
Tax Advantage Details
Intangible Drilling Costs (IDCs)
A large portion of well costs, including labor, fuel, repairs, and supplies used in drilling, may qualify as IDCs deductible in the year incurred.
Depletion Allowance
Income from producing wells may qualify for a depletion deduction over the life of the well.
Tangible Equipment
Costs for pumps, tanks, and wellhead equipment are generally capitalized and depreciated over time.
Tax treatment depends on individual circumstances and on the structure of each specific program. Figures shown are general and illustrative. Prospective investors should consult their own tax advisor. MRC Development Partners does not provide tax or legal advice.
