# A&D Reservoir Engineer

*/JobTypes/A&D_Reservoir_Engineer*

Departments: Business Development, Acquisitions and Divestitures (A&D), Corporate Planning and Economics, Energy Investment Banking, Technical Advisory, Reserves Management, Upstream Private Equity Deal Team.

## Job Type Profile

**Produces**: Produces reserve reports, well-level production forecasts, and economic cash flow models that dictate the financial valuation of oil and gas asset transactions. Delivers technical asset evaluations and bid recommendations directly to investment committees and executive boards.
**Ai Surface**: Decline curve generation, historical production data aggregation, and economic cash flow model population occur in structured digital environments. Interpreting reservoir anomalies, assessing operational risks, and formulating final transaction recommendations rely on human technical judgment and industry experience.
**Core Tools**:

- [phdwin](/JobTypes/A&D_Reservoir_Engineer/Products/phdwin)
- [IHS Harmony](/JobTypes/A&D_Reservoir_Engineer/Products/IHS_Harmony)
- [Enverus](/JobTypes/A&D_Reservoir_Engineer/Products/Enverus)
- [TIBCO Spotfire](/JobTypes/A&D_Reservoir_Engineer/Products/TIBCO_Spotfire)
**Responsibilities**:
- Evaluate subsurface data and historical production to forecast oil and gas recovery for potential acquisitions or divestitures.
- Build and run economic models to determine asset valuations, net present value, and rates of return under varying price decks.
- Analyze virtual data room materials, including well logs, type curves, and lease operating expenses, under strict deal timelines.
- Estimate proved, probable, and possible reserves in compliance with SEC or PRMS reporting guidelines.
- Collaborate with geologists, landmen, and finance teams to quantify subsurface risks and identify drilling upside in target properties.
