(2024050) How are ESP-lifted Wells Affected by Shut-ins for Offset Hydraulic Fracturing Treatments

The discovery of shale formations laden with hydrocarbons marked a significant turning point in the energy industry, especially because these formations exhibited minimal to no permeability. This inherent characteristic posed a substantial challenge for traditional extraction methods, leading to the advent of what is known as the unconventional play. The core of this approach is hydraulic fracturing, a revolutionary technique that not only generates high-conductivity fractures within the shale but also fosters the interconnection of these fracture networks, dramatically enhancing the extraction process. 

The advent of hydraulic fracturing has revolutionized the extraction of hydrocarbons from shale formations, characterized by minimal to no permeability. This paper discusses the mechanics of hydraulic fracturing, focusing on its role in creating high-conductivity fractures and interconnecting fracture networks to facilitate hydrocarbon flow. The study further explores technological advancements aimed at optimizing production plans, despite the inherent unpredictability of fracture outcomes. Emphasis is made on the impact of well spacing on fracture interaction. The overall extraction process is examined, highlighting the complex dynamics between well proximity and hydrocarbon recovery efficiency. 

Electrical Submersible Pumps (ESPs) are designed to apply a constant force to lift fluids in a well, with their flow rate being influenced by the pressure difference they generate. Optimal ESP design considers the formation's fluid yield, the fluid's density, and the required lift height, which together determine the pump's energy transfer needs. For high-productivity wells, the ESP's ability to increase pressure and consequently enhance flow capacity is crucial.

This research explores the impact of frac-hits, triggered by hydraulic fracturing in proximity to active wells, focusing on well performance metrics such as reservoir pressure changes, oil recovery, and the efficiency of Electrical Submersible Pumps (ESPs) in recovery. Through a comparative analysis of ESPs and Gas Lift systems in mitigating frac-hit repercussions, this paper aims to enhance strategic planning and risk mitigation in hydraulic fracturing operations.
