ESG and GHG Services

Greenhouse Gas (GHG) Emissions Disclosures - Gruy personnel have the expertise to provide Scope 1, 2, and 3 GHG emissions reports or audits conforming to various frameworks, applying robust standards, and summarizing complex scenarios with meaningful charts and graphs. With an excellent reputation, we generate credible deliverables that comply with policies published by governmental agencies.

Environmental, Social, and Governance - Our organization, with 75 years of experience, provides products that are recognized and accepted as accurate and objective. Gruy can assist with analyzing critical ESG criteria and metrics, helping to boost long-term sustainability and increase efficiencies.

Independent Reserves Reports

We regularly provide the engineering and economic forecasts required by the U.S. Securities and Exchange Commission for value reporting. H.J. Gruy and Associates, Inc. has a long-standing reputation for producing respected reserve estimates and economic projections, with accompanying reports, that conform to the guidelines published by the S.E.C. and the Financial Accounting Standards Board.

Our professionals have a wealth of experience forecasting production from conventional reservoirs and resource plays using modern decline curve analysis techniques.

Restructuring & Operations Support

We provide technical engineering support for corporate financial restructuring and bankruptcy proceedings. In these situations, Gruy has a proven record of positive outcomes for our clients. Furthermore, we have the capabilities to provide interim oil field operations with uninterrupted regulatory compliance, hazard assessment, and comprehensive site inspection for assets in transition.

Probabalistic Reserve Estimates

Our engineers and analysts regularly perform work involving probabilistic assessments of reserve volumes, geologic scenarios, original volumes in place, and economic metrics that are associated with individual entities or multi-system projects. We are proud of our ability to report probabilistic work in a clear and concise format that is appreciated by technical and non-technical clients.

Litigation & Expert Testmony Support

Gruy professionals are experienced and available to provide litigation support. Senior staff members also arbitrate disputes in cases requiring the need for unbiased negotiation. The firm will represent its clients before state, federal, or international governmental agencies when required. We recognize the complexities and considerations particular to litigation and provide independent consulting tailored to meet those needs.

Fair Market Value Estimates

Our firm is distinguished by offering fair market value analysis of domestic and international holdings. We are often asked to estimate value attributable to producing assets, nonproducing properties, and mineral interests. Gruy value determinations are often selected for use in tax disputes, estate valuations, litigation, and equity transfers. For international valuation work, we provide an independent assessment of political risk.

Integrated Reservoir Studies

These studies are multi-disciplinary investigations involving geophysics, geology, petrophysics, plus reservoir and operations engineering. A single project may include a complete reservoir characterization followed by numerical simulations using black oil, compositional, or EOR models. The study often includes risk assessment, facility design, and economic evaluation. An integrated field study may provide field depletion plans.

Reservoir Characterization & Simulation

Our teams of oil and gas professionals have the experience and knowledge to furnish complete reservoir descriptions. Through the expert application of geophysics, geology, petrophysics, and reservoir engineering, we can analyze historical performance and forecast performance of hydrocarbon reservoirs. Geophysical interpretation, exploration geology, production geology, well log analysis, core analysis, and reservoir fluid modeling are all included. We have expertise in numerical reservoir simulation ranging from single well modeling to full field studies.

Deep Water Gulf of Mexico Fields

Gruy professionals have played a major role in the evaluation of deepwater discoveries in both the Gulf of Mexico and offshore Africa. Our work includes prospect analysis, reservoir studies including production forecasting, and probabilistic modeling of reserves and projected cash flows. We have been retained to perform large-scale reservoir analysis, and we have been hired by transportation companies to verify the magnitude of resources for pipeline economic decisions.

Rigorous Field and Site Inspection

Our engineers and geologists are qualified to perform rigorous site inspections to document equipment and conditions when needed for transaction records or verification. Our inspections include both pen and paper checklists and digital platforms. Equipment and special features are identified and logged via GPS and extensive photographic records, with facility condition and operational status noted. A complete report in booklet and digital format is generated for the stakeholder.
