Insulative Base Fluid Prevents Premature ARA Reaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient-reactive subterranean formation additives (ARAs) used in hydrocarbon production wells can degrade or react prematurely at varying well-site temperatures, leading to reduced efficacy and interference with downhole equipment, especially when refrigeration or heating is unavailable or economically unfeasible.
Innovation Solution
A method and system involving an insulative base fluid and ambient-reactive subterranean formation additives (ARAs) are mixed in a storage tank, where the insulative base fluid maintains the treatment fluid at a temperature different from the ambient temperature, preventing premature reaction of the ARAs, and the treatment fluid slurry is introduced into a subterranean formation where the temperature triggers the ARA's reaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ambient-reactive subterranean formation additives are used in treatment fluids, then formation operations can be enhanced, but the additives may degrade or react prematurely at varying well-site temperatures
Solution Approach 1:
The patent changes the temperature parameter of the treatment fluid by using an insulative base fluid to maintain the fluid at a temperature different from ambient conditions. This prevents the ARA from reacting prematurely while maintaining its effectiveness during transport and delivery to the downhole location.
Solution Approach 2:
The insulative base fluid acts as an intermediary substance that isolates the ARA from ambient temperature conditions. This mediator allows the ARA to remain stable during transport while still enabling its intended reaction at the downhole location where temperatures are controlled.
2Reliability
If refrigeration or heating is used to control ARA temperature, then premature reaction can be prevented, but the cost and complexity increase
Solution Approach 1:
The treatment fluid system performs its own temperature control function through the inherent properties of the insulative base fluid. The base fluid automatically maintains the treatment fluid at a stable temperature without requiring external refrigeration or heating systems, thereby preventing premature ARA reaction while reducing system complexity and cost.
3Ease of operation
If ARAs are transported at ambient temperature, then logistics are simplified, but the additives may react prematurely reducing efficacy
Solution Approach 1:
The patent modifies the temperature parameter of the treatment fluid using an insulative base fluid, allowing the system to maintain temperature control during transport without complicating logistics. This enables simple transport while preventing premature ARA reaction and maintaining effectiveness.
