Petrel Petroleum System-based Play-to-Prospect Exploration: Integrated Exploration Techniques and Workflows using Petrel Exploration Geology Software

The overall goal of this 5-day course is for the participant to learn how to do play evaluation that integrates all the elements of the petroleum system into geologically-based, objective, consistent and documented results that can be used to understand and rank opportunities. The participants will learn to keep their play and prospect evaluation ‘live’ and usable whenever new understanding or data becomes available. Foremost, they will understand why integrated petroleum system-based exploration is an industry best practice.

The participant will learn how the fundamentals of petroleum systems and play concepts are an essential part of best practice Exploration. These fundamentals will be integrated in a series of exercises that demonstrate the basics of how play fairway mapping of the petroleum system elements is used to create play chance maps and assess play resources. The play level assessment of resources and play chance are then the basis for doing probabilistic volumetrics and determining the chance of success for the leads and prospects within the play.

Participants will evaluate a concession area using the Petrel Exploration Geology suite of integrated petroleum system-based play to prospect exploration tools and workflows (Petroleum Systems Quick Look and Play to Prospect Risk). The concession analysis goes from initial area screening, to play evaluation and lead identification, to the final assessment of the prospects developed from the leads. It includes learning to keep play and prospect evaluations ‘live’ and usable whenever new understanding or data becomes available.

The petroleum system-based workflows are all performed in Petrel using Schlumberger’s suite of Integrated Petroleum System-based Play to Prospect exploration tools and workflows (Petroleum Systems Quick Look and Play to Prospect Risk). The participants will know the theory behind the tools’ inputs and workflows and be able to use these tools to do play and prospect evaluations after this course.
