VARIABLE DIAMETER HOLE OPENER

TECHNICAL SUMMARY

A Variable Diameter Hole Opener (VHO) is a downhole drilling tool designed to enlarge a wellbore to multiple, specific diameters in a single run.

VARIABLE DIAMETER HOLE OPENER

KEY FEATURES

1. On-Demand Diameter Adjustment: Its cutting arms can be hydraulically activated and adjusted downhole, allowing operators to select the desired hole size without retrieving the tool.

2. Single-Run Efficiency: Eliminates the need for multiple trips to change fixed-size hole openers, dramatically reducing tripping time and cost.

3. Continuous Operation: Enables drilling and enlarging the hole section simultaneously when combined with a pilot bit.

4. Precision & Flexibility: Provides precise wellbore sizing for optimal casing placement, well design flexibility, and improved completion operations.

In short, it is a time-saving and cost-effective solution for creating multiple borehole diameters with one tool, enhancing operational efficiency.
