Integrated Reservoir Appraisal and Development Seminar

Integrated Reservoir Appraisal and Development Seminar

Duration:

This is a seven-day workshop that includes two days of travel and five days of coursework.

Who Should Attend:

This course is designed for petroleum engineers, geologists, geophysicists, petrophysicists, and supervisory personnel who are responsible for executing field development programs focused on primary-, secondary-, or tertiary-recovery projects in conventional terrigineous-clastic reservoirs. The geologic and engineering concepts and practices that are introduced are applicable to reservoirs spanning all depositional settings.

Purpose:

Students’ understanding of modeling and their ability to model geological features affecting reservoir performance will improve through the collection, observation, interpretation, and modeling of geologic, petrophysical, and engineering data. Methods for the cooperative collection, analysis, and interpretation of data to most efficiently appraise reservoir size and characteristics will be presented and practiced. Superb outcrops reveal complex but interpretable geologic features influencing reservoir development. Outcrop observations will be incorporated into geocellular models using wireline logs, cores, and petrophysical data collected from nearby boreholes. With this typical subsurface dataset, geocellular and reservoir models wil be evaluated and simulated within the five-day course.

The advantages and disadvantages to the implementation of various geologic concepts (e.g., lithostratigraphy vs. chronostratigraphy) and modeling steps (e.g., gridding, layering, property distribution) will be discussed and tested.

Description:

Engineers, geoscientists, and petrophysicists involved in field appraisal, development planning, and production forecasting work as teams using data collected from cores, outcrops, and wellbores (i.e., wireline logs, routine core analysis) to characterize, model, and simulate hydrocarbon reservoirs formed in continental to shallow-marine depositional settings. The identification, interpretation, and modeling of lithofacies, facies associations, and depositional systems from core, wireline-log, and outcrop data are emphasized as a method to realistically control rock-property distribution in geocellular models. Emphasis is placed on using stochastic or deterministic methods to accurately model the geological features controlling fluid flow. Teamwork culminates in a geocellular model evaluation and simulation; and a proposal of field development plans to increase reserves, accelerate field-production rate, or both.
