Wellbore Casing Fluid Transfer Assembly for Faster High-Pressure Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The formation of fluid transfer assemblies using spool irons for well stimulation systems is time-consuming and costly due to their high weight, short length, and high pressure rating, necessitating a large number of conduits and significant labor and material expenses.
Innovation Solution
A fluid transfer assembly formed from above-ground wellbore casings, which are longer and lighter than spool irons, coupled by connection assemblies to facilitate fluid flow, reducing the number of components needed and enabling a more efficient, cost-effective setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spool irons are used to form the fluid transfer assembly, then the assembly can withstand high pressure (15,000-37,500 psi), but the assembly becomes time-consuming and costly to form due to the large number of components required
Solution Approach 1:
The patent combines multiple short spool iron conduits into a single long wellbore casing to form the fluid transfer assembly. This merging reduces the number of components from multiple spool irons to just one wellbore casing, significantly decreasing assembly time while maintaining the required pressure withstanding capability of 15,000-37,500 psi.
Solution Approach 2:
The patent segments the fluid transfer function from the traditional multiple-component spool iron assembly and implements it as a single integrated wellbore casing. This segmentation approach eliminates the need for multiple connection points and assembly steps, thereby improving productivity without compromising pressure reliability.
2Reliability
If spool irons are used to form the fluid transfer assembly, then the assembly can withstand high pressure, but the cost of materials and labor increases significantly
Solution Approach 1:
The patent merges multiple expensive spool iron components into a single wellbore casing, reducing material costs and labor expenses. The single wellbore casing design eliminates the need for multiple high-pressure rated spool irons and their associated connections, thereby reducing manufacturing cost while maintaining the required pressure withstanding capability.
3Adaptability or versatility
If multiple short conduits are used to establish the fluid transfer assembly, then the assembly can be formed with standard components, but the assembly process becomes significantly time-consuming
Solution Approach 1:
The patent combines the function of multiple standard spool iron conduits into a single wellbore casing, reducing assembly duration from multiple connection operations to a single installation. This merging approach maintains adaptability by using a standard wellbore casing that can be deployed in various well stimulation configurations while eliminating time-consuming assembly steps.
4Ease of operation
If a large number of conduits are used to establish the fluid transfer assembly, then the assembly can accommodate the required flow path, but the weight and cost of each conduit increase the overall burden
Solution Approach 1:
The patent merges multiple heavy spool iron conduits into a single wellbore casing, significantly reducing the total weight of the fluid transfer assembly. The single wellbore casing maintains the required fluid flow capability for well stimulation operations while eliminating the cumulative weight of multiple high-pressure rated conduits.
