Open-hole packers may help isolate faults in multistage fracturing tight formations

摘要

Drilling and completion operations in faulted reservoirs present a unique set of challenges. With the advent of multistage fracturing and multistage acidizing, the requirements for drilling methodology in reservoirs that contain faults or major fractures have changed. Additional considerations must be made for horizontal wells in faulted reservoirs as they behave differently than vertical wells. Understanding the shortfalls of certain methodologies, as well as the challenges of drilling in these reservoirs, is key to success.
