Title: Innovations of James K Eastlack

Introduction

James K Eastlack is a notable inventor based in Anchorage, Alaska. He has made significant contributions to the field of fluid measurement and well treatment technologies. With a total of three patents to his name, Eastlack's work has had a considerable impact on the oil and gas industry.

Latest Patents

One of Eastlack's latest patents is a system and method for measuring fluid properties by forming a coaxial apparatus for insertion in a well. This invention is designed to measure the concentration of water in fluids flowing through a well, helping to determine which zone may be producing excessive quantities of water. The apparatus transmits microwave frequency range radiation within a section of the wellbore and utilizes a portion of the well casing along with a conductor member centered by spaced apart centralizers. This forms a coaxial transmission line within the wellbore. The apparatus can be traversed through the wellbore on a wireline type cable for continuous measurement of the water content in the water-oil mixture. A change in operating frequency of an oscillator is compared with power loss through the apparatus to identify the presence of water-in-oil or oil-in-water emulsions.

Another significant patent involves a well treatment method using sodium silicate to seal formations. This method includes a squeeze silicate operation carried out through coiled tubing to seal upper perforations in a well casing, preventing the flow of excess gas. The sodium silicate mixture contains a diverter material that rapidly builds a filter cake on the formation, effectively limiting the depth of penetration while providing a good seal against flow through the squeezed perforations.
