Training Course : GEOMECHANICS FOR UNCONVENTIONALS

Duration

2 Days

Learning goals

The ultimate goal of a geomechanics course is to enable course participants to build geomechanical

models and apply these successfully to field development issues. Given this is only a 2 day course it

should be seen as the first step to achieve this wider objective but we realistically expect course

participants after attending the course to:

Understand the workstep in building geomechanical models, and to be familiar in the theory

behind these worksteps,

Know what additional resources and standard textbooks can be used to build and apply

geomechanical models ,

Have clarity in understanding in the assumptions in geomechanical projects, and be in a

position to make a judgement on data requirements and input parameters. There will be

ample discussion on assumptions made in different approaches to building geomechanical

models,

Read and understand geomechanical reports provided by service companies,

Be able to challenge methods and assumptions in geomechanical reports with the report

authors and have an informed discussion to improve the end result of a geomechanical

project provide by a service company,

Avoid the fate of becoming a person that unthinkingly clicks buttons in a software

application to complete a workflow (“Nintendo-Geoscientists”). It is the aim of this course to

impart understanding of Geomechanics that creates confidence in building and applying

geomechanical models.

The main geomechanical applications in this course will on fractures and hydraulic stimulation

(fracture orientation and containment, re-activation of pre-existing fractures versus creation of new

fractures, shear fractures versus tensile fractures, fault stability), and wellbore stability. The course

time will be split in equal parts between (i) underlying theory, (ii) building and calibrating 1D

wellbore centric geomechanical models and (iii) building, calibrating and applying 3D and 4D

geomechanical models. Special emphasis is placed on using 3D seismic inversions as a data source,

specifically for unconventionals the course will cover:

Interdependence of elastic properties, pore pressure and stress state

What governs horizontal stress

Relationship of poro-elasticity and empirical PP-FG (Pore Pressure – Fracture

Gradient) methods, or “the right equation for every occasion”

o Fracture orientation

Jorg has 20 years of experience in academic research and in the oilfield service industry. In his career in the petroleum industry he became a world leader in time-lapse seismic applications and 3D and 4D geomechanical simulations applied to Petroleum Exploration and Production. He has extensive experience in technology development, technology application, teaching and mentoring. His recent work includes the lead in the development and deployment of a novel reservoir simulator which simultaneously solves the equations for fluid flow and geomechanics in one single simulation environment. Together with the team, Jorg deployed this new simulator to address geomechanical issues in field development planning, including well-bore stability in complex tectonic settings, seal-integrity, fault reactivation, inter-reservoir communication by crossflow and prediction of time-lapse seismic signals. Previously, Jorg discovered and implemented the concept of Seismic Geomechanics, a method to build and calibrate 3D and 4D geomechanical models using seismic data. This concept was conceptualized and implemented in a Research and Development Group, deployed the concepts as a consultant and lead the implementation as Petrel-based workflow, from model building to geomechanical applications. This work resulted in 4 patent applications, and an invitation by EAGE (European Association of Geoscientists and Engineers) to undertake a global lecture tour. In support of the lecture tour he wrote a text book on the subject of Seismic Geomechanics. Jorg has always enjoyed sharing and distributing knowledge and best practice. For example, he has continuously mentored younger and less experienced colleagues both formally through a mentorship programme at Schlumberger and informally by building teams. Teaching experience includes giving classes for NExT, the Schlumberger training arm, and undertaking a global lecture tour for EAGE. Jorg has also examined several PhD theses at leading Universities in topics that are related to his research. Jorg is a member of SPE, EAGE, SEG, and PESGB. Since June 2016 Jorg has served as the Education Officer on the EAGE Board.
