New technologies have made it possible for US unconventional reservoir Operators and Service Companies to substantially enhance the financial and production effectiveness of their fracturing treatments.

The in-person format of this workshop facilitates a thorough interactive determination of the properties of the existing fractures adjacent each segment of the new well, review of various action options, and the consequences of each option.

About the workshop: Frac-Driven Interactions (FDI) is the technology gateway to the next generation of fracturing treatments. It offers the unique benefits of giving us the information needed to determine, reliably and in real-time, when a new frac stage has reached its optimum effectiveness. The allure of this technology lies simultaneously in its dependability, ease and low cost of its application.

The target audience: This workshop will be highly beneficial for both Service Companies and Operators. It presents actions which each party can take in real-time and collaboratively to get optimum value and effectiveness from each stage of fracturing treatment in a horizontal well.

Workshop content: After a general discussion of the various aspects of FDI technology, attendees use their acquired knowledge to determine, during each separate frac stage, the extent and conductivity of the existing previous fractures adjacent the location of the new frac stage and implement treatment changes that are needed for new fractures to reach their planned and expected extent and conductivity for effective drainage of the reservoir.

Workshop content consists of two parts:

Part 1 (Morning session)

• Brief discussion of frac initiation and extension in horizontal wells
• In-depth discussion of Frac-Driven Interactions (FDI): their types and characteristics
• Review and analysis of multiple actual field data and assessment of the engineering characteristics of the created fracs
  • Growth pattern
  • Orientation
  • Length and height
  • Conductivity

Part 2 (Afternoon session)

Review and analysis of actual data from multiple completed well FDI’s, and group discussion of the range of options for real-time changes in treatment execution for each new well frac stage.

Instructors: George King & Ali Daneshy

About the workshop. Frac-Driven Interactions (FDI)s is the technology gateway to the next generation of fracturing operations. It offers the ability to decide, in real-time, when a treatment has reached its optimum effectiveness. It is ideally suited for today’s pad drilling and zipper fracturing practices. The allure of this technology is simplicity and low cost of its application. Post-mortem, the same data can be used to more cost-effectively determine the number and location of future wells for production of the reservoir.

The targeted audience. This workshop is recommended for both Service Companies and Operators. It presents the actions required by both sides to get the maximum benefits offered by the technology. Interaction between the two sides enhances the practical side of the discussions.

Workshop content. After a brief discussion of the technical background of the subject, this workshop presents actual field data to show how the technology helps determine the engineering characteristics of the created fractures and when they have reached their effective limit. It identifies the operational steps and set-up changes that are needed for the implementation of the process. Specifically, the workshop covers;

Brief review of the history of existing practices
Frac-Driven Interactions (FDI)s and lessons learnt
Real-time determination of frac vertical and lateral extents and growth pattern
Real-time evaluation of potential for production interference and well damage
Required set-up changes in real-time frac data acquisition systems
Guidelines for data-based real-time decisions
Application of FDIs for engineering process improvement/optimization

• Development planning (number and location of wells) & completion design (frac spacing, size, materials)
• Avoiding possible negative consequences of FDIs (wellbore mechanical and production damage)
• Application for future operations such as for re-frac’ing and EOR

Using actual field data, this course offers a comprehensive coverage of the positive and negative aspects of Frac-Driven Interactions (FDI) in horizontal wells. On the positive side it shows how careful analysis of the data can provide very valuable estimates of frac length and height, its orientation and growth pattern.

On the negative side, FDI can sometimes cause wellbore integrity damage in both the active and offset wells, loss of production and return of frac fluid and proppant inside the offset well that require expensive clean-up operations. This course discusses the prevailing types and effectiveness of remedial actions practiced by the industry.

Course contents, taught with actual field data, include:

• Mechanics of multi-cluster frac initiation and extension in horizontal wells
• Types of FDI, their causes and classification
• Prevailing damage mitigation techniques and their effectiveness
• Use of FDI for estimating critical frac engineering properties, including;
  • Length and height
  • Orientation
  • Growth pattern & detecting the influence of natural fracture

This course presents an easy-to-follow nuts and bolts of horizontal well fracturing, and various tools and techniques that are in use today for successfully producing extremely low permeability reservoirs.

Successful fracturing of a horizontal well requires deeper understanding of the relationship between reservoir and formation properties, in-situ stresses, well completion, and details of fracture design. Through numerous case histories and actual job results the course shows that many horizontal well fractures usually include a mix of axial (longitudinal) and transverse fractures along the length of the well. The cause of this behavior is traced back to completion techniques and fracture designs. The many case histories covered in this course include active US and Canadian tight reservoirs such as Bakken, Eagle Ford, Barnett, Cardium, Fayetteville, Granite Wash, Haynesville, Marcellus, Montney, Nordegg, Viking, and more. It presents the different fracturing strategies that are being used in different geologic formations, and the completion options that help their implementation.

Important engineering parameters for successful fracturing of horizontal wells include the well orientation with respect to the fracture, horizontal wellrach, type of completion (openhole or cemented liner), selection of the specific completion system and its functional reliability during the entire fracturing operations, the number and spacing of the fractures, the type and volume of frac fluid, injection rate, and the type and concentration of proppant. This course offers an in-depth review of the different completion techniques presently used by the industry and the operational strengths and weaknesses of each of them.
This course is designed specifically for practicing engineers and geologists. It is suited for all interested in improving the outcome of hydraulic fracturing treatments in horizontal wells, including drilling, completion, reservoir and production engineers as well as geologists and geophysicists. Both technical and management staff will benefit from attending this course.

Horizontal Well Fracturing Systems (3 days) Monday – Wednesday
This course presents a comprehensive review of the mechanics of fracture initiation and extension in horizontal wells. Using many case histories, the course discusses the operational features of different existing commercial completion systems in both open and cemented liner completions;and how and where they can be used for best production results. Other topics covered in the course include various materials, diagnostic systems, and their applications. The course ends with a review of options for re-fracturing horizontal wells completed with open or cemented liner.

Horizontal Well Fracture Interference  (2 days) Thursday & Friday
This advanced level course starts by reviewing the stress changes caused by an actively growing hydraulic fracture. It then examines how these altered stresses change the growth path and extension pressure of multiple fractures created in horizontal wells. Ultimately these changes can cause fracture coalescence, and the frequently observed fracture intersections with adjacent offset wells.Understanding the nature and cause of the interference will result in design of better fractures with higher production.

Fracture interference also offers an exciting novel source for determination of fracture parameters such as orientation, length, conductivity, and more. This interference can be between fractures in the same well (intra-well), or adjacent offset wells (inter-well). Through actual case histories, the course will show how fracture parameters can be evaluated by analysis of inter-well interference data. Intra-well interference data can be used for quality assurance of downhole tools, as well as qualitative determination of fracture orientation. The beauty of this technique is its ease of use, low cost, and high reliability of the outcome.

Development and integration of new and exciting drilling and completion technologies have facilitated innovative well architectures that allow substantially higher well productivity at much lower cost per barrel of produced fluid. These new architectures are now in use in all regions of the world and have enabled the Operators to achieve higher flexibility to manage the mix of fluids flowing from their reservoirs, achieving higher well productivity, and increasing the recoverable reserves. Managing the mix of fluids flowing from the well allows better control of water and gas production, and consequently higher production value and lower long term costs.

This workshop presents both technical and operational aspects of new completion techniques, where they could be used, and how to design them to fit specific reservoir conditions and operational requirements. Both management and technical staff will benefit from participation in this workshop.
