Title: The Innovative Contributions of Donald L. Hoyt

Introduction

Donald L. Hoyt is a notable inventor based in Houston, Texas, recognized for his significant contributions to hydrocarbon recovery technologies. With a total of five patents to his name, Hoyt has developed innovative methods that enhance the efficiency of oil extraction processes.

Latest Patents

One of Hoyt's latest patents is the "Modified push/pull flood process for hydrocarbon recovery." This invention involves injecting a recovery fluid into an underground formation through at least two wells. One well is designated as the production well and is shut-in for a soak period of about one to sixty days while the recovery fluid is injected through the second well. After the soak period, the shut-in well is converted to a production well, allowing for the extraction of hydrocarbons and other fluids while continuing the injection of recovery fluid through the second well.

Another significant patent is the method for "Recovering oil bypassed by a steam override zone." This process begins with drilling a production well below the oil-producing zone into an underlying interval. The well perforations in the oil-producing zone are then closed off, and the underlying interval is fractured to establish fluid communication. The production well is completed for production through the fractured portion, and the steamflood is controlled to increase pressure in the oil-producing zone, driving oil and steam downward to the new perforations for extraction.
