Summary
The course introduces basic shale candidate selection using petrophysical, geochemical and petroleum engineering information, then adds detailed practical knowledge of well planning, construction, stimulation, production and finally environmental conservation. It provides explanations, theory and practical understanding designed to recognize and build commercial completions and uses gas and oil play case histories from five commercial North American shales: Barnett, Eagle Ford, Gothic, Horn River and Marcellus.
Duration and Training Method
This is a two-day classroom course consisting of classroom lectures, construction examples and group exercises with field frac examples.
Participants will learn to:
- Assess general gas and oil production potential of candidate shale reservoirs.
- Select limiting factors in shale hydrocarbon production such as faults, regional fractures, fluid saturations, natural fractures and frac barriers.
- Estimate potential for initial production and decline rates.
- Formulate a shale gas development plan using multi-well pads and simple facilities.
- Design a well completion suitable for pressure containment and multi-stage fracturing.
- Select frac stages from logs and locate perforation clusters for effective hydraulic diversion.
- Design and execute a fracture stimulation.
- Develop flowback limits to effectively recover load fluids and preserve well energy for unloading water.
- Select the basic production equipment for the well.
- Supervise effective water use and flow back management.
Shales are the most abundant sedimentary rock and many, but not all, contain commercial quantities of gas and/or hydrocarbon liquids. Shales offer thousands of tcf of gas and hundreds of millions of barrels of oil as reserves, but they require careful selection and special stimulation methods to achieve commercial production and returns. The role of technology is critical in improving recoverable fluids.
