Multi-Pressure Fracking Adapter for Wellhead Pressure Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fracking methods require frequent replacement of wellhead systems to match higher pressure ratings for fracking operations, leading to increased costs, downtime, and safety concerns due to the need for high-pressure equipment availability and handling.
Innovation Solution
The implementation of a multi-pressure fracking adapter, such as an Integrated Double-Studded Pack-Off Adapter, allows for the use of a lower-pressure wellhead system with a higher-pressure fracking valve assembly, eliminating the need for frequent equipment changes and reducing handling and testing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lower-pressure wellhead system is used for normal production, then equipment cost and complexity are reduced, but it cannot be used for high-pressure fracking operations
Solution Approach 1:
A multi-pressure adapter is introduced as an intermediary component between the lower-pressure wellhead system and the higher-pressure fracking valve assembly. The adapter has a first end that interfaces with the lower-pressure wellhead and a second end that interfaces with the higher-pressure fracking valve assembly, allowing the two dissimilar pressure-rated components to be connected and enabling fracking operations without replacing the entire wellhead system.
2Reliability
If the wellhead system is replaced with a higher-pressure system for fracking operations, then pressure rating compatibility is achieved, but downtime and operational time increase
Solution Approach 1:
The multi-pressure adapter is designed to be pre-configured with threaded connections that match both the lower-pressure wellhead system and the higher-pressure fracking valve assembly. This preliminary design allows for quick attachment and detachment during fracking operations, eliminating the need for time-consuming wellhead system replacement while ensuring pressure rating compatibility.
3Reliability
If the wellhead system is frequently replaced for fracking operations, then pressure rating compatibility is maintained, but manpower costs and operational complexity increase
Solution Approach 1:
The multi-pressure adapter serves as a reusable intermediary component that remains in place during fracking operations, eliminating the need for frequent wellhead system replacements. This single adapter can accommodate multiple fracking valve assemblies, reducing manpower requirements and operational complexity while maintaining pressure rating compatibility throughout the fracking process.
4Reliability
If high-pressure equipment is purchased or rented for fracking operations, then pressure rating compatibility is achieved, but equipment cost increases
Solution Approach 1:
The multi-pressure adapter provides universal compatibility between lower-pressure wellhead systems and higher-pressure fracking valve assemblies. This single adapter design can interface with various fracking valve assemblies, eliminating the need to purchase or rent multiple high-pressure wellhead systems or specialized high-pressure equipment, thereby reducing equipment inventory requirements and associated costs.

AI summary
An improved method for fracking operations, the improvement comprising measuring the last piece of casing, cutting the casing to the measured length, installing a suspension device on the last piece of casing, landing the suspension device inside the well-head, installing pack-off bushing around the suspension device, engaging locking pins to maintain the pack-off bushing's position, removing blowout preventer, installing a two-way check valve into the mandrel, attaching a multiple pressure rated fracking adapter rated up to twice the pressure rating of the well-head casing, testing the sealing elements of the fracking adapter to insure proper sealing, attaching a fracking valve assembly to the fracking adapter, where an operator fracks a hydrocarbon well for enhanced production without compromising safety by eliminating potential leak points and reducing the costs and time required for preparing and conducting fracking operations and returning the well to production.
