Shallow and Deep Marine Sedimentation: Principles and Application

Introduction

This 5-day intensive Shallow and Deep Marine Sedimentation training course is designed for petrophysicists, geologists, geophysicists, or engineers who use core, borehole images, log data, core data, and production data to produce or understand facies produced in a shallow and deep marine sedimentary environment. The training course aims to develop a G&G workflow that exploits a variety of geological data essential to produce an accurate clastic marine reservoir model.

Upon successfully attending this training course, the participants will be able to utilize all forms of data used to build a deep and shallow marine geological model. Ranging from mud logs, rock cuttings, thin-sections, core, borehole images, log data, seismic and geological analogs. The participant will build and interpret facies logs, to create detailed facies maps deposited within a shallow coastal and deep-sea slope setting. Participants will be able, despite their different working sectors, to deal with deep marine sedimentary models, interpret facies logs, and understands varying sand body architecture and geometries. As well as learning about the different tools needed to acquire the most accurate data to derive accurate facies models.

This training course will highlight:

• Fundamental different sedimentary plays within the marine environment
• Sedimentary flow processes that deposit within a marine system
• Analysis of mud logs, rock cuttings, core and thin sections to build robust facies types and facies associations
• Interpret the key features of borehole images, and interpret the dip data to determine palaeoflow direction and sand dispersal
• Understanding and utilizing geological analogs to provide the input parameters to build a marine reservoir model

Objectives

By the end of this training course, participants will learn to:

• Understand different shallow and deep marine facies models and their sedimentary setting
• Interpret mud logs, core, and thin sections to produce shallow and deep marine facies logs and a facies model
• Utilize borehole images, log data, ECS and NMR to generate marine electro facies
• Identify accurate geological analogs, to derive input parameters for geological models
• Understand upscaling, which honors geological data to create accurate static and dynamic geological modeling

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
