Title: Innovations by Erwin D. Hernaez

Introduction

Erwin D. Hernaez is a notable inventor based in Houston, Texas, recognized for his contributions to the field of engineering and technology. He holds two patents that showcase his innovative approach to solving complex problems in the oil and gas industry. His work is characterized by a focus on enhancing operational efficiency and safety in well treatment processes.

Latest Patents

One of his latest patents is the Flow Activated Valve. This valve assembly is designed to close off a zone in a well for further treatment above a plug. It features a valve member that is initially pinned in an open position, allowing flow up to a predetermined level without dislodging the valve plug. If a perforating gun misfires, a replacement gun can be run in with flow, as the plug remains in position for flow through it. Conversely, flow around the plug above a predetermined level will shear retainers for the plug, allowing it to land on its seat and close flow in a downhole direction for treatment.

Another significant patent is the Disintegrating Agglomerated Sand Frack Plug. This frack plug includes a sealing element that reforms when set to hold differential pressure. The element is granular and uses adhesive to hold the particles together while allowing the shape to reform under setting force. The adhesive can be broken down with a chemical agent, enabling the seal to reform at the desired depth. Consequently, the structural components can disintegrate, allowing the seal assembly to fragment into small pieces that can be circulated out of the well or allowed to drop to the hole bottom.
