Solution Overview

Problem

The complexity and cost of well completion operations are increased due to the need for multiple trips into the borehole to install completion equipment, which complicates the process of extracting hydrocarbons or injecting water into subterranean formations.

Innovation Solution

A single trip completion system that includes a packer, washdown shoe, fluid loss control device, circulation valve, formation isolation valve, and barrier component, allowing for the installation of both upper and lower completion sections in a single trip by establishing multiple fluid barriers within the borehole.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple trips are used to install completion equipment, then the completion process can be performed with simpler individual operations, but the overall complexity and cost increase

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple completion operations into a single integrated completion system that can be installed in one trip. The system merges the lower completion, upper completion, packer, valves, and barrier components into a single assembled unit that is run into the borehole once, eliminating the need for multiple separate trips while maintaining operational simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The completion system is divided into distinct functional segments (lower completion with screen, packer assembly, circulation valve, formation isolation valve, and barrier components) that can be independently designed and assembled, then integrated into a single installable unit. This segmentation allows for simplified individual operations while achieving complex overall functionality in one trip.
