This session will discuss the impacts of well-to-well interference from a reserves and resource development standpoint.

This session discusses the growing design considerations needed to effectively stimulate unconventional rock. We will discuss the workflows and information needed to execute an effective stimulation design in unconventional rock and set up the high level discussion around stimulation design. How does workflows effectively pass multi-disciplinary information to the completion design team, and how do the teams balance effective design, with well economics.

Water volumes and proppant loading have increased in recent years generally resulting in improved production. However, excessive volumes have shown to be problematic with infill development and existing production. This session will present results of well spacing and the resulting frac-to-well interaction, prevention methods, production responses and economic considerations.

This Session will present applications of Integrated Diagnostics to evaluate stimulation distribution effectiveness and stimulation geometry domains in the wellbore/near-wellbore and far-field dimensions. The focus will be on diagnostic efforts that provided actionable results and recommendations for improvement. Examples will be presented that demonstrate accelerated optimization of well completions and resource development and improve understanding of well-to-well or frac-to-frac behavior. Diagnostic methods presented will include: Fiber Optics Distributed Sensing, Pressure Monitoring, Chemical Fluid Tracers, MicroSeismic Monitoring, and Downhole Video Camera among others.

Presentation: Intervention Based DFO Used to Evaluate Parent-Child Interaction Along the Well Bore
Fracture driven communication has been observed in many recent industry case studies, and historically diagnostics have largely been non-existent or not interpreted. Fortunately, there are many scientific conclusions that can be drawn from stress shadowing, frac shadowing, fracture coalescence, frac and soak, hydraulic fracture closure during production, interactions between wells being fraced and wells being concurrently drilled, and fracture/fault interactions. This session will investigate these dynamic reservoir interactions and attempt to gauge the positive and negative implications of each.

Presentation: Using Field Offset Well Pressure Response to Improve Completion Design
A known issue, exacerbated by depletion from a producing parent well, fracture asymmetry driven by pressure gradients in the reservoir cause drastic underperformance of infill child wells, and loss of productivity in parent wells. This session will focus on industry efforts to mitigate this issue through the use of pressure maintenance (preloads, pushbacks, recharges), parent well refracs, child well completion design changes, and overall development optimization. No industry consensus of best practices or preferred methods have been observed, and play characteristics only further complicate the problem. This session will focus on new and novel methods for mitigating Parent-Child Depletion.

Frac optimization and parent/child interactions do not stop at the border. Canada’s unconventional Montney and Duvernay plays are in different places along the development curve, with areas of these plays being in delineation and some being in harvest. In this session, we will explore how the Canadian plays are dealing with changing completions techniques to optimize full field development.

The Mid-Continent and Eagle Ford are home to some of the nation's most prolific wells. Many of these prolific wells are the first wells in an area which results in severe depletion to combat during infill drilling.
