Horizontal wells have become the industry standard for low permeability oil and gas reservoirs. Because these reservoirs have poorer quality pay, it takes a good, well-planned completion and fracture stimulation(s) to make an economic well. Even in a sweet spot in these reservoirs, good completion and stimulation practices are required; otherwise, a marginal or uneconomic well will result. But what are good completion and stimulation practices in horizontal wells in these low permeability reservoirs?
- What are the objectives of horizontal wells and how do we relate the completion and stimulation(s) to achieving these goals?
- Where do we land our laterals for best well performance?
- How many completions/stimulations do we need for the best performance and economics?
- How do we maximize the value from the horizontal wells?
- How do in-situ stresses and rock properties affect a multiple fractured horizontal well?
- When should a horizontal well be drilled longitudinally or transverse?
These are just a few questions to be addressed during this talk. This talk will focus on some of the key elements of well completions and stimulation practices as they apply to horizontal wells in lower permeability reservoirs. Optimization and case studies will be shown and used to highlight the importance of reservoir permeability and geomechanics to the successful design and execution of a multi-fractured horizontal well. These studies will highlight the importance of lateral length, perforation cluster spacing, number of stages, and fracture half-length. This talk will discuss the various completion choices such as cased and cemented, open hole with external casing packers, and open hole, “pump and pray,” techniques and how the completion is affected by the permeability and geomechanics of the reservoir. _____________________________________________________________
