Title: The Innovative Contributions of Peter L Lagus
Introduction
Peter L Lagus is a notable inventor based in Olivenhain, California. He has made significant contributions to the field of underground formation analysis, holding a total of seven patents. His work focuses on methods that enhance the understanding and measurement of fracture pressures in geological formations.
Latest Patents
Among his latest patents is a method for measuring fracture pressure in underground formations. This innovative approach involves placing a variable volume device in direct communication with a test interval in a borehole. The expansion of this device increases pressure in the test interval to reach the formation's fracture pressure. By monitoring the pressure in the test interval, the fracture pressure can be accurately determined, with the expansion of the device being carefully controlled to minimize fracture extent within the formation.
Another significant patent is the method of hydrofracture in underground formations. This method initiates or causes fractures in an underground formation by creating an isolated interval with an adjacent guard region using a suitable packer assembly. The pressure and flow within the test interval are increased to initiate fractures while monitoring conditions to detect fracture propagation relative to the borehole axis.
Career Highlights
Peter has worked with several companies throughout his career, including Systems, Science and Software and S-Cubed. His experience in these organizations has contributed to his expertise in the field of underground formation analysis.
