Abstract
This study presents an avant-garde approach for predicting and optimizing production in tight reservoirs,
employing a dual-medium unsteady seepage model specifically fashioned for volumetrically fractured horizontal
wells. Traditional models often fail to fully capture the complex dynamics associated with these unconventional
reservoirs. In a significant departure from these models, our approach incorporates an initiation pressure gradient
and a discrete fracture seepage network, providing a more realistic representation of the seepage process. The model
also integrates an enhanced fluid-solid interaction, which allows for a more comprehensive understanding of the
fluid-structure interactions in the reservoir. This is achieved through the incorporation of improved permeability
and stress coupling, leading to more precise predictions of reservoir behavior. The numerical solutions derived fromnite element method, ensuring high accuracy and computational
effciency. To ensure the model’s reliability and accuracy, the outcomes were tested against a real-world case, with
results demonstrating strong alignment. A key revelation from the study is the significant difference between
uncoupled and fully coupled volumetrically fractured horizontal wells, challenging conventional wisdom in the
field. Additionally, the study delves into the effects of stress, fracture length, and fracture number on reservoir
production, contributing valuable insights for the design and optimization of tight reservoirs. The findings from this
study have the potential to revolutionize the field of tight reservoir prediction and management, offering significant
advancements in petroleum engineering. The proposed approach brings forth a more nuanced understanding of
tight reservoir systems and opens up new avenues for optimizing reservoir management and production.
