Unconventional Gas Fracturing: Leveraging Experience from Success
and Failure

5 – 7 November 2012

Dubai, UAE | Amwaj Rotana - Jumeirah Beach Residence

About this Workshop

Abstract

Future potential for gas production lies among others in unconventional gas reservoirs such as tight gas and shale gas. These reservoirs are economically marginal and cannot be developed using conventional technologies. Therefore, they require unconventional drilling, completion, stimulation, and reservoir management approaches. Many unconventional reservoirs are being developed around the globe and considerable expertise has been developed in recovering unconventional gas. This know-how is being transferred to the Middle East region with engaging new technology developments. To achieve success in developing the regional unconventional reservoirs, it is vital to leverage all experiences, regional and global, which offer potentially significant rewards in extracting needed energy for the region.

These challenging unconventional reservoirs must be hydraulically fractured to yield commercial gas production rates. Developing cost effective fracturing technologies is critically needed to increase well productivity and ensure commercial development of unconventional reservoirs. Enabling existing fracturing technology to develop tight gas reservoirs have been applied worldwide. Additionally, much research is devoted on optimizing fracturing processes and materials. It is vital to understand the unique characteristics of unconventional reservoirs to design all phases related to hydraulic fracturing; characterization of the reservoir, sweet spot selection, Well design,  pre-frac testing, fracturing process and its real time monitoring, post-frac evaluation, and overall field optimization. As progress is made in the learning curve of producing natural gas from the regional unconventional reservoirs, developing innovative technologies is vital to improve recovery from these reservoirs. This understanding has been reflected in the technical sessions carefully selected for this workshop. The sessions are divided into three days representing 1) the planning, 2) the execution and 3) the evaluation of a fracturing job:

  • Reservoir characterization, petrophysics, geology and geophysics, geomechanics, sweet spot selection
  • Completion designs to place multiple hydraulic fractures
  • Pre-frac evaluation and testing
  • Fracturing materials; chemicals, additives, proppant, water management (technical considerations, influence of local resource constraints and logistical challenges)
  • Execution and real time monitoring of fracturing job
  • Fracturing case histories – stories of success and failure
  • Post-frac evaluation; fracture cleanup, production data diagnostics, well testing, microseismic
  • Looking ahead – innovative technology development

This workshop aims at identifying good practices to help accelerate the learning curve associated with the development of unconventional gas reservoirs in the region. These practices should consider the regional constraints such as the unique reservoir characteristics, economic environment, and water supply. The workshop is designed to blend regional and international knowledge associated with tight gas and shale gas reservoirs. Specifically, this knowledge is focused on multistage hydraulic fracturing applications. The workshop includes keynote speeches, technical presentations, panel discussions, Q&A, and informal multi-disciplinary discussion with focus on opportunities to evaluate and optimize fracturing treatments in the region. It is anticipated that the workshop will lend itself in establishing knowledge transfer among attendees as case histories are discussed in detail and evolving technologies are outlined.

Visa Information

SPE Middle East, North Africa and India will assist in providing a visa invitation letter, upon request in writing, to confirmed registrants after receiving full payment of registration fees. Visa invitation letters take five days to issue from the date of request and it is the delegate's responsibility to obtain their own visa. SPE cannot issue the visa nor can we guarantee it will be obtained.

 

Workshop Guidelines

Format

Three (3) days of informal discussions prompted by selected keynote presentations and discussions. Workshops maximise the exchange of ideas among attendees and presenters through brief technical presentations followed by extended Q&A periods. Focused topics attract an informed audience eager to discuss issues critical to advancing both technology and best practices. The majority of the presentations are in the form of case studies, highlighting engineering achievements and lessons learnt. In order to stimulate frank discussion, no proceedings are published and the press is not invited to attend.

Documentation

  • Proceedings will not be published; therefore, formal papers and handouts are not expected from speakers.
  • Work in progress, new ideas and interesting projects are sought.
  • Professionally-prepared visual aids are not required; handwritten view graphs are entirely acceptable.
  • Note-taking by participants is encouraged.

Attendance

Registrations will be accepted on a first-come, first-serve basis. The Steering Committee encourages attendance from those who can contribute to the workshop most effectively either in discussions or with posters. A mix of attendees in terms of geographic origin, companies and disciplines will be encouraged.

Workshop Deliverables

  • The Steering Committee will appoint a “scribe” to record the discussions and to produce the full workshop report for SPE.
  • This report will be circulated to all attendees as the workshop deliverable within 4–6 weeks following the workshop. The copyright of the report is with SPE.
  • PowerPoint presentation materials will be posted on a specific SPE URL address after the workshop Provision of the materials by the speakers will signify their permission for SPE to do so.

Commercialism

In keeping with ATW objectives and the SPE mission, commercialism in posters or presentations will not be permitted. Company logos must be limited to the title slide and used only to indicate the affiliation of the presenter and others involved in the work.

Attendance Certificate

All attendees will receive an attendance certificate attesting to their participation in the workshop. This certificate will be provided in exchange for a completed Workshop Questionnaire.

Continuing Education Units

Attendees at this workshop qualify for SPE Continuing Education Units (CEU) at the rate of 0.1 CEU per hour of the workshop.
