Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireline systems require extensive time and resources to assemble, operate, and disassemble, due to the need for multiple machines, vehicles, and labor, which can be inefficient and unsafe.
Innovation Solution
A transportable and telescopically deployable wireline derrick system that can be quickly positioned above a wellhead, with a winch assembly and pressure control equipment that can be easily coupled and secured, allowing for rapid deployment and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional wireline systems use multiple machines and vehicles for assembly and operation, then the system can perform wireline operations, but the assembly and disassembly process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent combines the wireline derrick, winch assembly, pressure control equipment, and support structures into a single integrated mobile unit mounted on a trailer. This merging eliminates the need for separate crane operations and multiple vehicle setups, allowing the entire system to be deployed and disassembled as one compact unit, thereby dramatically reducing assembly and disassembly time while maintaining full operational capability
Solution Approach 2:
The mobile wireline derrick unit is designed to perform multiple functions including wireline handling, pressure control, and support operations all within a single integrated platform. The system can be transported by standard trailers, positioned at wellheads, and disassembled for relocation, making it a universal solution that replaces multiple specialized pieces of equipment and reduces overall operational time
2Adaptability or versatility
If conventional wireline systems use cranes and multiple vehicles, then the system can be assembled and operated, but the space required at the wellsite increases
Solution Approach 1:
The patent employs a telescopic derrick structure where the upper section nests within the lower section when not in use, and components such as the winch assembly and pressure control equipment are compacted into the trailer. This nesting capability allows the system to occupy minimal space during transport and storage while still providing full functionality when deployed at the wellsite
3Ease of operation
If conventional wireline systems require extensive assembly and operation setup, then the system can be configured for operations, but the complexity and resource consumption increase
Solution Approach 1:
The patent integrates the wireline derrick, winch assembly, pressure control equipment, and support structures into a single mobile unit that can be transported on standard trailers. This merging reduces the number of separate components that need to be assembled and coordinated, simplifying the deployment process while maintaining all necessary functional capabilities through a unified design

AI summary
A wireline derrick has a telescopically arranged frame, a sheave, a winch, and pressure control equipment. Pressure control equipment (PCE) is positioned within the frame. An upper section of the derrick can extend and retract relative to a lower section. When the wireline derrick is in the retracted position, an upper PCE assembly is positioned adjacent to the lower PCE assembly. The upper PCE assembly is laterally moveable, such that when the wireline derrick is in the extended position, the upper PCE assembly may be moved into and out of axial alignment with the lower PCE assembly. When in a fully deployed condition, the lower end of the upper PCE assembly is removably coupled to the upper end of the lower PCE assembly. A transport trailer is adapted to move the wireline derrick from a horizontal position to a vertical position and cause the upper section to extend and retract.
