DESIGNED FOR
Production, completion, reservoir, and drilling engineers; geologists concerned with well performance and production enhancement; field supervisors, production foremen, engineering technicians; production and exploration managers; those involved in vertical, horizontal, and multilateral wells, conventional and unconventional reservoirs
YOU WILL LEARN HOW TO
Understand basic reservoir properties that influence reservoir performance, as well as the potential for formation damage and its removal - this includes a basic understanding of rock mechanics
Demonstrate an understanding of clay mineralogy, how formation clays can cause damage, and current methods to prevent this type of damage from occurring
Differentiate how sandstones are damaged as compared to limestones and dolomites
Determine why scale, paraffin, and asphaltenes can cause significant reduction in production and how you can control this type of damage
Prevent damage during drilling, completion, and production phases - this includes everything from underbalanced drilling to the use of new drill-in and completion fluids, to general production practices
Detemine what is important in the evaluation of damage - is your damage real or is it related to restrictions in the completion system? Without a proper understanding of poor well performance, stimulation approaches may be unsuccessful
Remove damage. The subject goes beyond just acidizing, which is thoroughly covered. It also includes non-acid approaches such as wellbore washes, perforating techniques, hydraulic fracturing application, etc.
ABOUT THE COURSE
Formation damage seems to be inevitable and it is costing you and your company money! Whether it can be prevented or removed economically or must be accepted as the price for drilling and producing a well will depend upon many factors. The activity with horizontal and multilateral wells has brought about a renewed interest in this subject. Many are trying to prevent formation damage during drilling and completion through the application of underbalanced drilling. This approach cannot work for everyone and some are beginning to question the validity of expecting no formation damage when underbalanced drilling is used. Others are using the newer drill-in/completion fluids in hopes of getting the formation damage problem under control. This renewed interest points out that the industry realizes we have a long way to go to overcome formation damage. These subjects and many more are addressed in this fast-paced, extremely informative course covering all aspects of formation damage: How it happens, how to prevent it, how to determine if you have it, and, if so, how to do away with it. A review of basic geology, depositional environments, and reservoir properties helps set the stage for an understanding of the various damage mechanisms in both vertical and horizontal wells. This understanding helps to dispel many of the age-old myths and barroom stories about how formations are damaged. Examples, case histories and class team exercises are used throughout the course to bring out key points on this important industry subject. Of particular importance is the well completion method and how it influences the ability to overcome formation damage. Current relevant technical papers presenting new ideas and concepts are reviewed in class helping participants stay abreast of the latest technology. Attendees leave the course with an enhanced knowledge of formation damage and state-of-the-art technology for overcoming its effect on the company’s economic success, along with a comprehensive manual that complements the presented material.
COURSE CONTENT
Geological/Depositional Environment Review: How homogeneous or heterogeneous are these formations from which we produce and what is the influence on formation damage?
Reservoir Properties Review: What properties most influence the effect of formation damage? Is your reservoir performance influenced by stress sensitivity?
Damage Mechanisms: How are sandstones and carbonates damaged, how does formation mineralogy and clay chemistry influence damage? What about fines migration, scale, paraffin and asphaltenes?
Damage Prevention: Drilling, completion, and production methods, drilling/completion fluid and additive selection, clay control
Evaluation of Damage: Production performance, logging, pressure analysis review
Damage Removal: Acidizing materials and methods, non-acid approaches, such as wellbore washes, perforating techniques, and hydraulic fracturing to bypass damage
