Latest Patents

**Drag Block Assembly with No External Fasteners.** This invention describes a downhole fastening apparatus built around a sleeve with longitudinal receiving slots on its outer surface. Drag blocks sit within the slots and include activation elements that bias them outward, along with gripping elements designed to engage wellbore casing. A retention element at the sleeve’s uphole end helps keep the blocks engaged without external fasteners.

**Jetting Device for Wellbore Annulus.** This tubular jetting device uses inlet and exhaust ports connected by channels. Inlet fluid enters through openings in the device’s inner and end surfaces, while exhaust fluid exits through openings in the end and outer surfaces. The arrangement supports fluid jetting into a wellbore annulus.

Career Highlights

Howitt’s listed inventions address practical challenges in downhole fastening and fluid delivery. The drag block assembly focuses on retaining gripping components within a sleeve, while the jetting device provides a defined path for fluid flow through a tubular tool.
