Applied Petrophysics for Low Resistivity Thin– Bedded Formation

Introduction

Thin bedded reservoirs are increasingly common exploration targets. However, evaluating such formations is difficult due to challenging and sometimes misleading data.

This program will cover all aspects of Petrophysical analysis in thinly bedded reservoirs and will train attendees to select the best interpretation techniques based on the data available and the known characteristics of the formation.

This course focuses on different techniques in tackling various types of thinly bedded reservoirs, including laminated sand shale sequences, thin layers of different types of clean sands and thin beds in carbonates.

Objectives

    IDENTIFY POSSIBLE HC POTENTIAL FOR THIN BEDDED SEQUENCES:

    Learn the Petrophysical techniques in interpreting log data from low resistivity, thin-bedded sequences in order to identify possible HC sources.

    CHARACTERIZE VARIOUS TYPES OF THINLY BEDDED RESERVOIRS:

    Analyze various determining characteristics of thinly bedded reservoirs such as that in laminated sand shale sequences, in cleans sands, and in carbonates.

    UNDERSTAND THE CHALLENGES IN DETECTING PAY ZONES & THEIR ACCURATE EVALUATION:

    Identify the challenges and pitfalls in detecting pay zones in thin-bed reservoirs and their accurate evaluation. APPLY THE RIGHT TECHNIQUES FOR EVALUATING THIN BED RESERVOIRS:

    Identity in which logging techniques have been useful, what have been most successful, and the available technologies that can help better evaluate these reservoirs.

Training Methodology

The program is delivered in a combination of lecture-style and practical experiential learning method is results-oriented; based on an adult learning concept. The course is designed as a blended environment of presentation; workshops; group work; practical exercises; field application/ case studies, analysis and several industry videos showing all processes; and general discussions. The course will include real case studies in the oil and gas industry. Most of the case studies have been presented in international journals by the instructor. Pre & Post-course assessments will be used to measure the effectiveness of this training and measure the skill and ability of participants.
