Relocatable MPD System Walking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Managed Pressure Drilling (MPD) systems require the use of pickers and cranes for setup and relocation, leading to time-consuming and costly operations, especially when moving between oilfield locations, which hinders efficient oil and gas drilling operations.
Innovation Solution
A relocatable MPD system equipped with a base, tank, and manifold that uses hydraulics and walking systems, such as stomper pads or cam wheels, to move without the need for cranes or pickers, allowing for rapid reconfiguration and relocation on oilfields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional MPD systems use pickers and cranes for relocation, then equipment can be moved between locations, but the operation becomes time-consuming and costly
Solution Approach 1:
The MPD system incorporates a walking system with stomper pads that can dynamically change position, allowing the entire system to walk or slide to new locations without requiring external cranes or pickers for relocation
Solution Approach 2:
The MPD system is self-sufficient for relocation through its integrated walking system, eliminating the need for external heavy equipment like cranes and pickers, thereby reducing both time and operational costs for moving between drill locations
2Adaptability or versatility
If MPD equipment is moved using bed trucks, then relocation is possible, but additional equipment is required and setup time remains substantial
Solution Approach 1:
The walking system is integrated directly into the MPD system structure, extracting the need for external bed trucks and other heavy transport equipment, thereby simplifying the overall equipment requirements while maintaining full mobility capability
Solution Approach 2:
The walking system serves multiple functions: it enables the MPD system to move to new locations, positions equipment during setup, and eliminates the need for separate transport equipment, making the system universally adaptable for all relocation needs
3Stability of the object's composition
If the MPD system remains stationary during rig movement, then equipment stability is maintained, but the rig cannot efficiently move between drill holes
Solution Approach 1:
The MPD system transitions from a static configuration to a dynamic walking system that can actively move with the rig, maintaining stability during operation while enabling rapid relocation between drill holes at the same pad location
Solution Approach 2:
The walking system acts as an intermediary between the MPD equipment and the ground, providing a mobile platform that maintains equipment stability while enabling the rig to move efficiently between multiple drill locations

Function Achieved in This Case
This solution significantly reduces setup and relocation time, potentially from 36 hours to as little as 1 hour, saving time, money, and eliminating the need for bed trucks, enabling faster rig operation and reducing operational costs by up to 50% compared to traditional methods.
Implementation Method 1
each of said plurality of stomper pads comprising a pair of perpendicular hydraulics: vertical hydraulics and horizontal hydraulics; wherein the vertical hydraulics are adapted lift the stomper pads off the ground
Implementation Method 2
while the base is off the ground, the horizontal hydraulics slide the stomper pads form a first proximal position to a second distal position
