... are described in detail to permit readers to replicate the approach. One field case study with five horizontal wells is presented. Three infill wells were drilled between two primary wells of varying ages. All wells are shale oil wells with approximately 7,700 ft lateral sections. The recovery of each tracer...

During field execution, the parent wells going diagonally across the infill wells were shut in and plug set. The parent well parallel...

A DFO deployed with a 0.6" OD, 23,000-foot-long carbon fiber rod to acquire DAS and DTS for post frac flow, completion, and interference evaluation. This paper will dive...

... of wells (5H through 8H) were drilled in the western half of the unit with the same spacing strategy. These wells were completed in November 2013. These eight wells are referred to as "step-out" legacy wells. The unit was then down spaced with eight infill wells (9H-16H) resulting in a stacked Middle...

... decided to pro-actively learn about FDIs and to apply the learnings to frac defense. Frac defense not only protects the primary well, it also helps to prevent asymmetrical fractures in the infill well. We provide methodology used to design and implement FDI defense. Additionally, we also show how we...

... was to determine if far-field diverter is effective at reducing or eliminating FDI's, resulting in long-term inter-well communication. Two wells, "A" and "B", were sampled for the presence of oil and water tracer offset to the infill well. Table 3 shows the offset oil communication table for well "A". Well...

... Abstract In the Midland Basin, infill wells have high potential of experiencing well-to-well fracture interference or "frac hits". Rock stress alteration around parent wells affect child fracture interactions thus impacting completion effectiveness, well productivity, and well spacing. Endeavor...

... Abstract Hydraulic fracturing treatments in shale infill wells are often impacted by existing parent well depletion and asymmetrical fracture growth. These phenomena can result in excessive load water production, deposition of proppant and deformation of casing in the parent well...

Infill performance can be highly variable, with operators making great efforts to ensure infill wells perform comparable to or better than existing parent wells. This challenge will become more magnified in the unconventional industry...
