The North American unconventional resources energy growth driven by the combination of horizontal drilling, completion tools and hydraulic fracturing innovations has revitalized some conventional plays across the globe that were considered marginal prior to the unconventional boom. This paper presents the workflows utilized to implement unconventional technologies that have resulted in incremental hydrocarbon resources being unlocked.

A multi-domain approach is utilized to understand the results from the application of horizontal drilling, completion tools and hydraulic fracturing innovations to the Turner play. High tier log and core data is used initially to create petrophysical and geomechanical models. Numerous petrophysical and geomechanical models are generated based on the uncertainty in model building. Appropriate models are selected based on fracture pressure matching and production history matching techniques. These models are then used to drive the design and optimization process of future offset wells.

Characterization of the reservoir (permeability range, pressure and fluid saturations) has led to the understanding that completion techniques used in unconventional plays (slickwater fluid system with tight cluster spacing) cannot be blindly applied. An understanding of fracture geometry and reservoir quality enables changes to be implemented on lateral landing, stage count and job size resulting in incremental production.

The importance of reservoir characterization and forward modeling of the application of horizontal technologies is crucial to ensuring efficient allocation of resources to maximize production. This paper showcases the application and evolution of unconventional technologies and workflows to conventional plays to gain incremental production results.
