The Art of Green Field Development: The Challenge of Uncertainties and Risks

Abdolrahim Ataei, Keng Seng Chan

Outline

Green fields today mostly can be regarded as marginal fields and successfully developed. This one-day course elaborates the strategies for green field development. It covers the complete assessment of the oil and gas recovery potential from reservoir structure and formation evaluation, oil and gas reserve mapping, their uncertainties and risks management, feasible reservoir fluid depletion approaches, and to the construction of integrated production systems for cost effective development of the green fields.

Session 1: Do you know your Green Field?

  • How marginal is your field? Basic definitions and challenges.
  • Reservoir structure, connectivity, and uncertainties
  • Drive mechanisms and development strategy (phasing)
  • Managing the development risks

Session 2: Where are the oil and gas reserves?

  • Oil and gas distribution and uncertainties
  • Determination of potential reserve
  • Decision tree and scenario definitions to handle low case
  • Clustering small fields

Session 3: How to deal with uncertainties?

  • Well placement, optimisation, and design
  • Early production systems
  • Surface and subsurface integration to save cost
  • Role of new technology and data acquisition

Session 4: Can you add value and lower cost?

  • Well design and completion: A life saver!
  • Low cost well architecture
  • Smart well completion
  • Surface production system integration

Who Should Attend

  • Reservoir engineers
  • Geologists and petrohysicists
  • Drilling and completion engineers
  • Production engineers
  • Well integrity engineers
  • Field development managers
  • Oil field investment financial analysts

CEUs

Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and or/ certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PHD).

Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.

 

Instructors

Abdolrahim AtaeiAbdolrahim Ataei is currently a principal reservoir engineer at Petroleum Resource Development at PETRONAS and has more than 24 years of industrial and academic experiences. He has worked in several positions in the E&P business, including offshore operation and production as well as well completion design and drilling. He has also worked on several FDP projects for brown field and green field in Malaysia. As a member of PETRONAS Technical Review Committee for the past 6 years, he was involved in several field development plans for green and brown field developments and their challenges. He will share some of those examples with the audience.

Ataei is also collaborating with UTP (University technology PETRONAS) by supervising the MSc and PhD projects as well as supporting the academic programs. He has published more than 20 technical papers in various international journals and conferences on different area in reservoir description and characterization. His areas of interest are reservoir dynamics, EOR, reservoir connectivity, and well deliverability estimation. He is also expert in gas condensate reservoir behavior and condensate banking modeling and evaluation.

Keng Seng ChanKeng Seng Chan is currently a principal reservoir engineer for PETRONAS, Malaysia. He was an SPE Distinguished Lecturer for the season of 2009-2010 and the recipient of the 2011 North Asia Pacific Region Technical Award for Production and Operations. Throughout his 35-year career in the oil and gas industry, he has held various key positions in research and development, new technology and field operation technical support and management, and performed as the reservoir study team leader and advisor for various field redevelopment projects. At this present position, he also served as the advisor for technical endorsement of Production Sharing Contracts (PSC) for offshore field development and redevelopment in Malaysia.  He holds BS and MS degrees in physics from the University of Rangoon, MS and PhD degrees in chemical engineering from the University of Florida.
