The course is aimed at both understanding and reducing uncertainty during well planning and design. Through discussion, you will learn how to consider both data-driven uncertainty as well as process-driven approaches. The ultimate aim is to see if Expected and High Cases can be appropriately risked such that percentage likelihood can be assigned to each.

It is recommended for any person involved in well design and for those that also act as peer-review from other departments and managers that need to understand the risks involved. 

The Uncertainty in Pore Pressure Prediction course is run in the style of a workshop and is comprised of presentations, discussion and simple exercises.  

Over 1.5 days, you will cover the following topics: 

• Where uncertainty can arise in well planning and how to mitigate it 
• Current industry approaches for predicting pore pressure – the good, bad & ugly 
• Uncertainty and limitations in pore pressure algorithms  themselves
• Determining pore pressure ramps  more accurately
• The significance of human influence 
• Quantifying meaningful uncertainty and how it impacts final well design and costs
• More about this course's content and schedule.

The main geomechanical applications in this course will focus 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 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 worksteps 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 (if available).

ABSTRACT

This highly acclaimed and constantly evolving course (now in its 11th year), is a must for all geoscientists wanting to understand rock physics principles, their application to amplitude interpretation (including AVO reflectivity and elastic inversion products) and how they can be applied to reduce drilling risk.

More than 90 courses have been given in the last decade. In-house presentations have been given to multi-nationals including Shell, ENI and British Gas, while representatives from more than 70 companies have attended public courses in the USA, UK, Holland, Italy, Norway, Mexico, Trinidad, India, South Africa and Australasia.

Dr Rob Simm has granted Ikon Science the rights to deliver this course by our approved tutors; Dr Mike Bacon, Dr Mark Sams and Dr Michel Kemper. More than 165 courses have been given in the last decade.

WHO SHOULD ATTEND?

The course is designed for all geoscientists who wish to understand the principles of interpreting seismic data using rock physics models and gain awareness of how this may impact the perception of risk in exploration and production drilling. Attendees will receive a fully documented manual with text discussion, including all illustrations shown in the course. The course is a combination of lectures and practical exercises - these exercises use our RokDoc software, but no previous experience of the package is required.
