Equipment Specifications

Hydromechanical Piercing Perforation (HMPP) is an advanced technology widely used in the oil and gas industry, as well as in various material processing applications. This method leverages hydraulic energy to create precise perforations in different environments, enabling superior control over liquid and gas flow dynamics. It also contributes to improved well performance. By utilizing hydromechanical perforation technologies, operators can significantly reduce well preparation time and associated costs, while boosting overall productivity.

High-Quality Production Casing Perforation

This method ensures efficient preparation for squeeze cementing and hydraulic fracturing, establishing a reliable connection with the formation and effectively forming caverns in four projections, without requiring device orientation.

Minimized Risk of Cross Flows Behind Casing

The gentle perforation process preserves the strength of the production casing and the integrity of the cement sheath outside the perforation interval.

Safe Operations for Hazard Class 4 Facilities

HMPP facilitates safe operations in challenging conditions, minimizing risks and boosting operational efficiency.

The HMPP technology is well-suited for operations on absorption wells and horizontal wells.

The HMPP technology is not only effective for standard perforation, but also offers solutions for the following challenges:

Well abandonment
Emergency response perforation
Perforation at shallow depths
Perforation in wells with a dual casing setup
Restoration of injectivity and flow rates, transition from production to injection wells, and bottomhole zone flushing
Operations on wells with fluid absorption
Addressing challenges in organizing perforating-explosive operations

Requirements for HMPP operations:

Workover team
Tubing lifting unit
SIM-35 pumping unit
Process fluid
Well survey data (marker joint referencing)
HMPP equipment

HMPP Procedure

Wellbore Preparation –—Scraping and conducting a drift test to ensure wellbore integrity.
Installation and Deployment – Running the HMPP piercing device to the specified perforation depth using a tubing lifting unit.
Depth Positioning and Activation – Aligning the device using marker joint referencing, adjusting it to the required depth, and initiating perforation.
Equipment Retrieval – Lifting and dismantling the HMPP equipment upon completion of perforation.
This technology significantly enhances well productivity and operational safety, making it an essential solution in modern hydrocarbon production.
