Oil and Gas Reserves Evaluation

Overview Objectives Audience Methodology Contents Certificate FAQ's

Course Overview

Oil and gas reserves evaluation plays a fundamental role in guiding energy industry companies’ strategic, operational, and financial decisions while facilitating transparency, accountability, and sustainable resource management. Oil and gas reserves evaluation is a complex process involving various steps and expertise from multiple disciplines.

This Oil and Gas Reserves Evaluation course will cover the definitions of and uses for, oil and gas reserves estimates and how to comply with each of the industry standards (SPE-PRMS) and regulators’ (US SEC) versions of the reserves requirements. Participants will learn how geoscience and engineering evaluation methods should be used for compliance with reserve estimates, the differences in the evaluation assumptions between PRMS and SEC, and how the categorization of reserves reflects the inherent uncertainties in reserve estimates.

Learning Objectives

At the end of this Oil and Gas Reserves Evaluation training course, delegates will be able to understand:

Reserves Fundamentals: Understand the categorization and definitions of reserves.
Reserve Evaluation Methods: Learn techniques for evaluating reserves.
Petroleum Resources Management: Familiarise with standardised reserve management.
Regulatory Aspects: Explore regulatory involvement, like the US SEC.
Guidelines for Estimation: Study methods for reserve estimation.
Well Test Analysis: Understand reserve evaluation using well tests.
Recovery Factor Estimation: Forecast recoverable hydrocarbons, including unconventional resources.
Tight Reservoirs: Study assessment of unconventional tight reservoirs.
Unconventional Resources: Explore classification, sweet spots, and myths.
Reserves Reporting: Understand ownership and reporting of reserves.
Economics and Markets: Explore economic factors affecting reserves.
Reserve Progression: Gain insight into how reserves evolve.

Target Audience

This Oil and Gas Reserves Evaluation Training is suitable for a wide range of professionals but will greatly benefit Geologists, geophysicists, reservoir engineers, reserves managers, bankers, and government officials involved in reserves reporting, reserves auditing, and reserves estimations

Training Methodology

This training utilizes various proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented. The program will be interactive and practical. There will be work in groups and pairs as well as individual exercises and everyone will get an opportunity to discuss their issues with Oil and gas reserves evaluation. Each day will end with time to produce an action plan for delegates’ continuing development.

Pre & Post course assessments will be used to measure the effectiveness of this training.
