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.
