Hinged Wireline Enclosure for Overspray Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireline assembly and overspray containment devices fail to effectively contain and redirect overspray from both the stuffing box and sheave, leading to environmental hazards and inefficiencies in the oil and gas industry, as they either require frequent pad replacement or do not address sheave-related overspray.
Innovation Solution
A wireline assembly enclosure with hinged halves, apertures, and a sealing material that forms a liquid-tight compartment around the stuffing box and sheave, featuring an adjustable bar clamp and absorbent pads to capture and redirect overspray, allowing for customizable fit and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If absorbent pads are placed around the wellhead to mitigate overflow, then overspray containment is improved, but maintenance time and operational costs increase due to frequent pad replacement
Solution Approach 1:
The enclosure is divided into two separable halves that can be independently removed and reattached, allowing maintenance personnel to access and replace absorbent pads without replacing the entire enclosure system, thereby reducing maintenance time while maintaining containment effectiveness
Solution Approach 2:
The enclosure acts as an intermediary containment structure between the wireline assembly and the surrounding environment, providing a permanent housing that holds absorbent pads in place and redirects overspray, eliminating the need for frequent direct intervention with the pads themselves
2Object-affected harmful factors
If containment devices focus only on the stuffing box, then leakage containment is improved, but overspray from the sheave remains unaddressed
Solution Approach 1:
The enclosure is designed to simultaneously address multiple sources of contamination by providing a unified containment structure that encloses both the stuffing box and sheave, making the device versatile enough to handle both leakage and overspray issues in one integrated system
Solution Approach 2:
The patent merges the containment functions for the stuffing box and sheave into a single enclosure structure, combining what were previously separate containment needs into one comprehensive solution that addresses all overspray and leakage sources
3Ease of manufacture
If a fixed enclosure design is used, then manufacturing simplicity is improved, but adaptability to different wireline configurations is reduced
Solution Approach 1:
The enclosure incorporates adjustable components including variable positioning of absorbent pads and configurable bar clamps that can be adjusted to accommodate different wireline assembly configurations, allowing the same enclosure design to adapt to various operational requirements without requiring custom manufacturing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The enclosure effectively contains and redirects overspray, reducing environmental hazards and operational costs by providing a durable, customizable, and easy-to-maintain solution for wireline assemblies, ensuring a secure and efficient containment of lubricants and other materials.
Implementation Method 1
A sealing material is disposed partially about a perimeter of the first and second halves such that a seal is formed when the two halves are together in the closed configuration
Implementation Method 2
The enclosure also has a plurality of apertures. In various embodiments a stuffing box, lubrication tubing, and other materials pass through the apertures into the interior compartment

AI summary
A wireline assembly enclosure. The wireline assembly enclosure has a first half and a second half which define an interior compartment. The first and second halves are attached via a hinge and move from an open configuration to a closed configuration. The enclosure also has a plurality of apertures. In various embodiments a stuffing box, lubrication tubing, and other materials pass through the apertures into the interior compartment. A sealing material is disposed partially about a perimeter of the first and second halves such that a seal is formed when the two halves are together in the closed configuration. The sealing material is also disposed about a perimeter of the plurality of apertures. An adjustable bar clamp inside the interior compartment of the enclosure clamps hardware in place. The enclosure is secured around a stuffing box and sheave in order to contain overspray from a wireline.
