Session I: Establishing Primary Business Drivers Obtaining High
Initial Production (IP) and its impact on economics

Chairs: Kimberly Mitchell, Marathon Oil; Leonard Kalfayan, Hess

This session endeavors to set the stage for the workshop by establishing primary buiness drivers in the Bakken. Operator, service provider, and academic perspectives for the Bakken will be presented and discussed. As an example, obtaining high IP and its impact on economics is of particular importance and interest.

Session II : Economic Assessments – Methods and Case Studies

Chairs: Christopher Jablonowski, University of Texas at Austin; Shah Kabir, Hess

In the planning stages of tight oil projects, operators assess economic feasibility, select initial depletion strategy, stage capital investments, and develop contingency plans. The analysis is often complicated by uncertainty in the input parameters. In this session, speakers will share their experiences regarding the economic and engineering analysis that takes place both prior to project sanction and during the production phase. Case studies will be the basis for discussion.

Session III : Optimum Fracturing – Common Options and Case
Histories

Chairs: David Cramer, ConocoPhillips; Ali Daneshy, Daneshy Consultants Int’l.

Hydraulic fracturing of horizontal wells is now the standard practice for optimizing productivity in the Bakken. This session will review some of the fracturing systems in use and their features that are specific to Bakken completion and well stimulation. Discussion will also focus on case examples and results, and implications for future development.

Session IV : Optimum Fracturing – Technology Trends

Chairs: Ali Daneshy, Daneshy Consulting Int’l; Joseph Ayoub, Schlumberger

The productive life of Bakken wells can be extended by practices, such as re-fracturing. These practices pose completion challenges requiring introduction of new technologies, including novel fracturing procedures and fluid systems with special properties for the unique conditions in the Bakken. These considerations and associated applications will be addressed.

Session V: Diagnosing Long-Term Fracture Performance

Chairs: Peter Valko, Texas A&M University; Mohamed Soliman, Halliburton Energy Services

Various diagnostic tools are available before, during, and directly after well stimulation. This session will discuss well-established diagnostic techniques (minifrac, pressure fall-off, microseismics, tiltmeters, tracers), as well as novel ideas addressing the issue of changes in the long-term production performance of the created fractures.

Session VI : Forecasting Reservoir Performance

Chairs: Mohamed Soliman, Halliburton Energy Services; Archie Taylor, Continental Resources

Different techniques for forecasting reservoir performance with emphasis on the unique aspects of oil production from the Bakken shale will be the focus of this session. Both numerical and analytical techniques will be discussed. The suitability and aspects of different approaches are still being debated. Field cases including simulation studies will feature prominently.

Session VII : Monitoring Reservoir Performance and Evaluation

Chairs: Peter Valko, Texas A&M University; Archie Taylor, Continental Reources

A pressing issue with monitoring reservoir performance is knowing the difference in production decline under ideal wellbore conditions and when wellbore restrictions or fracture damage has occurred. Unneeded wellbore cleanouts are expensive; so, identifying candidates for cleanout and/or re-stimulation is essential. Decline curve analysis is also crucial for reserves reporting. This session will discuss ways of analyzing production (and possible pressure) history.

Session VIII : Dealing with Formation Damage and Production Chemistry Issues

Chairs: Leonard Kalfayan, Hess; Randy LaFollette, BJ Services

A key issue with Bakken wells is scaling. This session will focus on inorganic scale remediation and prevention, including traditional inhibitor delivery and fracturing proppant-based methods. Lessons learned from water analysis studies in the Bakken will be discussed to address questions such as: What water chemistries that may be important to scaling potential are produced from different zones? What compatibility issues exist with available fracturing make-up water sources? What are the resulting scale types?

Session IX: Best Practices/Way Forward —Designing Well Architecture and Stimulation Technology

Chairs: David Cramer, ConocoPhillips; Randy LaFollette, BJ Services

The session is designed to provide an overview of well architecture, completion, and stimulation in current geographic areas of industry activity. Emphasis will be on technology: what works, what doesn’t work, and why. The intent is also to relate production results to key reservoir properties and associated stratigraphic and geomechanical challenges. Changes in well architecture parameters will be compared to production results. Topics for presentation and discussion should include effects of well azimuth, length, and attitude (toe-up vs toe-down), liner type, staging methods, and hydraulic fracturing processes.
