Distinguished Seminar Series: Challenges of Unconventional Infill Development
February 28 @ 10:00 am - 11:00 am
Juan David Estrade Benavides, Schlumberger OneStim
Infill development is changing the landscape of North American shales as operators try to avoid bypassing pay in their operating acreage. Although capitalizing on increased drilling and completion efficiencies can reduce development costs, tighter well spacings may limit well performance. Operators that do not carefully plan and design their developments often find they must make larger investments in infill wells to achieve production comparable to that of legacy wells. Simultaneously, the legacy wells can be negatively affected as they may be temporarily shut in (delaying production), experience increases in water-to-oil ratio, or even require intervention to restore production after being sanded out. This presentation addresses engineering workflows and presents surface solutions to mitigate detrimental fracture-driven interactions between infill (child) and legacy (parent) wells.
Bio: Juan David Estrada holds a bachelor’s degree in chemical engineering from Universidad de los Andes in Bogota, Colombia. He has more than 13 years of international experience in hydraulic fracturing. Currently, he works as North America West Division Technical manager for Schlumberger OneStim responsible for integrated unconventional completions. During the last 10 years he has focused in the development of unconventional resources. In addition, Juan David has an extensive background in matrix acidizing, water conformance and sand control for conventional reservoirs.
