This 5-day course emphasizes the multi-disciplinary nature of hydraulic fracturing, covering the "Reservoir Engineering" aspects, integrated with the "Fracture Mechanics" aspects, and coupled with "Operational" considerations. This integration is absolutely necessary in order to present how to recognize opportunities for fracturing from hard rock tight gas, to offshore "frac-pack" completions, to multi-fractured horizontal shale wells. Also covered is how to estimate required data for planning and preparing preliminary job designs, how to design, perform, and analyze pre-frac tests, and finally how to arrive at an "optimum" final design. Along with an Introduction to Fracturing, the course covers Reservoir Response, Rock Stresses, Fracture Geometry, Fracture Pressure Analysis, Fracture Fluid & Proppant Selection, Multi - Fractured Horizontal Wells, and Field Application & Quality Control.
A complete set of course materials and lunch is included in this course.
*Participants will need to bring a laptop with Microsoft Excel to each day of this course*
What You Will Learn
â€¢Data - The importance of the many variables affecting fracturing, and how to recognize critical parameters for specific applications, and how to find/measure critical data.
â€¢ Candidates - How to recognize wells/formations as good fracture candidates, and Water Fracs - How to evaluate formations as candidates for water fracs.
â€¢ Goals - A step-by-step procedure for estimating variables & developing preliminary treatment design goals and pump schedule designs.
â€¢ Multi-Fractured Horizontal Wells - How to develop strategies for horizontal wells (longitudinal vs. transverse, fracture spacing from reservoir and fracturing considerations, etc.)
â€¢ Fracturing Pressure Analysis - How to use fracturing pressure analysis to â€œcheckâ€ the preliminary parameter estimates and to develop a final design pump schedule.
â€¢ Materials - How to evaluate/select appropriate materials (fluid/proppant) for fracturing applications.
â€¢ Optimization - Combining all aspects of â€œfracturingâ€ for fracture optimization.
â€¢ Critical Quality Control - How to perform the critical field QC for good fracturing results.
The course is based on visual aids keyed to a comprehensive manual. The manual contains the most up-to-date collection of state-of-the-art fracturing concepts/practices, and provides an excellent reference for later applications. The manual also includes multiple, detailed, solved case history examples ranging from Australian tight gas wells, to Gulf of Mexico "frac-pack" completions, to North Sea tip screen out (TSO)treatments. Practical applications during the week are built on two complete, detailed, real problems. Several "problems" are available insuring each attendee works on application similar to their current operating environment.
Reservoir Engineering: Fundamental â€œReservoir Engineeringâ€ aspects of hydraulic fracture design, predicting well performance improvement, etc.
â€¢ Rock Mechanics: How in-situ stresses are generated as a function of depth, reservoir pressure, and geologic structure. How is in-situ stress measured?
â€¢ Fracture Mechanics: What are the major variables that control fracture growth, fracture geometry, and proppant placement. How do we recognize the critical parameters for a specific application?
> Height: What controls fracture height and how to estimate this?
> Modulus: What is rock modulus and how do we estimate/measure this critical variable?
> Fluid Loss: What controls fluid loss while pumping and how do we measure this
(& when should we use fluid loss additive)?
> Toughness: How do we determine â€œFracture Tip Effectsâ€?
â€¢ Fracture Pressure Analysis: How to design (& then analyze)pre-frac tests to measure critical design parameter(s), be that fluid loss, height growth, or something else.
â€¢ Pump Schedule: What are the different â€œtypesâ€ of fracture pump schedules, and how (& when) fracturing pressure data defines the final design pump schedule.
â€¢ Materials: What are the important properties for fracturing materials(fluid/proppant) and how should these properties be weighted and evaluated for specific applications?
â€¢ Field Procedures: Critical field operating procedures for job execution and QC. What tools are available (and how do they work) for post-frac evaluation?
