Latest Patents

One of Castillo's latest patents is titled "System and method for stress field based wellbore steering." This invention discloses a system, method, and computer-readable medium for developing an earth formation. A tool conveyed in a borehole induces a stress in the earth formation proximate to the borehole. A sensor assembly obtains measurements of a physical property of the borehole at various azimuthal locations. The values of the physical property indicate the induced stress in the formation. A processor forms an image of the borehole using these measurements, estimates the azimuthal variation of the induced stress with borehole depth, and alters operational parameters of a device for developing the earth formation based on this estimation.

Another notable patent is the "Fracturing method to reduce tortuosity." This invention features a series of jet nozzles with a telescoping structure designed to impact the borehole wall and initiate a fracture. The nozzles can be extended through fluid pumped through them or with mechanical force from within the bottom hole assembly. The leading ends of the telescoping assembly are sharp and hardened to facilitate the initiation of a formation fracture in an open hole. The design ensures that jetted fluid from at least one jet will be within 22.5 degrees of the location of maximum formation stresses, thereby reducing the tortuosity of the created fractures.
