Title: The Innovative Contributions of Betty J Felber
Introduction
Betty J Felber is a notable inventor based in Tulsa, OK (US). She has made significant contributions to the field of subterranean formation treatment, holding a total of 5 patents. Her work focuses on improving methods for treating highly conductive zones in subterranean formations.
Latest Patents
One of her latest patents is titled "Method for sweep improvement utilizing gel-forming lignins." This invention involves treating highly conductive zones of subterranean formations with aqueous fluids that contain gel-forming amounts of water-soluble basic lignins. The suitable treating fluids consist of about 2 to about 8 wt. % sodium hydroxide solution. The lignin solutions gel within the formation due to their reactivity with oil-water and/or the rock matrix. Additionally, following the injection of the gel-forming fluids, acidic gas can be injected to facilitate gel formation. Another significant patent is "Silicate activated lignosulfonate gel treatments of conductive zones." This patent describes the treatment of highly conductive subterranean zones with aqueous fluids containing gel-forming amounts of water-soluble lignosulfonate and silicate. The suitable treating fluids contain about 2 to about 5 weight percent sodium or ammonium lignosulfonate and sodium silicate at a weight ratio of SiO₂ to lignosulfonate of about 0.2 to about 1.
