Workshop Overview

The personalities of Engineers and Geoscientists are often very different. When it comes to Corporate Risk Assessments and company incentives, the rewards for these individuals are often counter to the overall goals of superior Intellectual Property and stand-out well performance amongst peers. For example, drilling team metrics and operating personnel objectives are often counter to the geological target objectives of ‘staying in the zone’ to realize maximum possible production. Such divergent drivers can cause conflicts between individuals; the overarching goal should be professional teamwork driving towards Company Success.

Technological advances in recent years (i.e. drilling further and faster than ever before) now have many Operating Companies questioning whether their horizontal wells are being drilled too fast for their own good. An understanding of Cost vs Accuracy trade-offs is critical for the best drilling decisions to be made, and for the maximum benefits to be drawn from unconventional resources.

This Introductory Level course will compare and contrast ‘staying in the target zone’ via geo-steering and monitoring along the way with ‘drilling ahead for maximum rate-of-penetration’ (which equates to less ‘non-productive’ time). This course will lay the foundation for a greater understanding between the disciplines and in particular address the Operational issues that make the Drilling Team ‘uncomfortable’.

Proudly presented by both PESA and SPE in Western Australia, this course is suitable and highly recommended for both Geologists and Engineers.

Presenter: KC Oren

KC Oren has been in the drilling and geoscience sectors of the Oil and Gas E&P Industry for over 30 years. Early in his career Oren was a technical trainer for directional drilling and sub-surface surveying at Eastman-Whipstock. He then held various technical and management positions with Smith International, Teleco and Halliburton before turning his hand at technical sales for both drilling tools and steerable systems, and later marketing E&P software solutions at Munro-Garrett International, GeoGraphix, Landmark and Halliburton.

He now resides in Frisco, Colorado and is employed by Horizontal Solutions Int’l (HSI) as Vice President for Sales and Marketing of HSI’s TrueTime™ Solutions in the Northern North America and Internationally.

Arrow 31/03/2015 SPE WA Lecture Series:Using Integrated Asset Modelling to Improve Oil and Gas Planning Decisions in a Volatile Market

Using Integrated Asset Modelling to Improve Oil and Gas Planning Decisions in a Volatile Market

Crude Oil has been our primary energy driver for a number of decades and the current fluctuation in oil price puts many operators’ future investments in limbo.  Natural gas exploration, production and distribution however, have increased tremendously in recent years. Oil production primarily focuses on maximizing liquid hydrocarbon recovery and minimizing gas production, whereas gas production is typically driven by long term contracts generating both opportunities and challenges in optimizing reservoir production.

Integrated asset models provide a pathway for planners and engineers to combine their views from often conflicting objectives.  IAM tools enable optimal hydrocarbon resources to be recovered by oil and gas companies. The details required for building an asset model depend on the type of optimization problem we strive to address. It is common practice for E&P companies to use the same tools for optimizing different types of reservoirs; however gas reservoirs are significantly different to manage when compared to oil reservoirs.

Asset management teams in E&P companies, joint venture partners and Government regulatory authorities rely upon the Integrated Asset Models for making informed decisions.  

There are a number of applications for IAMs and this presentation will focus on:

  • How IAM is important as a corporate planning tool
  • How market based models provide robust optimization for oil and natural gas exploration and production
  • Facility representation in IAM – how much detail is optimal and for what purpose
  • How to find system bottlenecks and enforce facility constraints for field development optimization
  • Good forecasting models – how they aid exploring challenging fields (High CO2, H2S etc)


Presenter - Dr Andrew Wadsley

Dr Andrew Wadsley has more that thirty-nine years’ experience in the petroleum industry - starting as a well-site petroleum engineer with Shell International in 1975, and has been a consultant petroleum engineer for over twenty-five years.

Dr Wadsley is the Executive Chairman and Founder of Stochastic Simulation Limited, an unlisted public company founded in 2008; he was adjunct Associate Professor in Petroleum Engineering at the Curtin University of Technology; he was Chief Scientist for Paradigm Geophysical; and was Reservoir Engineering Expert on the Gorgon CO2 Sequestration Review Committee for Department of Industry and Resources, Western Australia.
Dr Wadsley has been Umpire for resolution of a Gas Reserves Dispute, and has been called as an Expert Witness in cases ranging from reservoir engineering, the mercury content of natural gas, to gas production operations.
He is a member of SPE and EAGE, and the Society for Industrial and Applied Mathematics.  He received a Bsc (Hons), University Medal in Mathematics from the Australian National University in 1970, an MSc in 1972, and a PhD (Mathematics) from the University of Warwick (UK) in 1974.
