Title: Innovations by David B Larson

Introduction

David B Larson is an accomplished inventor based in Broken Arrow, OK (US). He holds 2 patents that showcase his expertise in engineering and fluid dynamics. His innovative contributions have significantly impacted various industries, particularly in the fields of fluid manipulation and well cementing technologies.

Latest Patents

One of Larson's latest patents is a "Reciprocating drive/pump system and reciprocating capillary viscometer utilizing same." This inventive reciprocating pump is designed as a syringe pump that includes a cylinder, an actuated piston, and a floating piston. A chamber is created between the actuated piston and floating piston, which can be filled with a pressurant to establish the quiescent pressure of the test fluid. The capillary viscometer consists of a capillary tube wound around a heated mandrel, a differential pressure transducer, and a reciprocating pump. The test fluid is pumped at a known rate from a first chamber through the capillary tube into a second chamber. The pump is then reversed, allowing the test fluid to return to the first chamber, creating a continuous, reciprocating process.

Another significant patent is the "Method and device for manipulating ferrofluids for use in cementing wells." This invention discloses a novel method and device for manipulating ferrofluids, which may include hydraulic cement, finely divided magnetic particles, a binding agent or surfactant, and a liquid medium. The compositions are designed to be stable in a magnetic field, allowing for effective cementing in wellbores. The movement of the slurry results in a 'scrubbing' action against the casing and formation surfaces, enhancing the bonding of the cement.
