The challenges of parent and child wells

摘要

Production performance changes due to the interaction between parent and child wells can be modeled using the microseismic-derived fracture permeability values in a reservoir model. In the last two years, there has been an increase in the drilling of infill wells, also known as child wells. The aim of these infill wells is to produce hydrocarbons left in place from older (or parent) wells, or to continue field development with increasingly modern completion designs. The common experience shared throughout the industry is that the interaction between parent and child wells has often proven to decrease EUR and capital efficiency for both parent and child wells.
