Latest Patents

One of Hoyal's latest patents is titled "Sediment transport by fully developed turbulent flows." This invention presents a method for modeling a hydrocarbon reservoir by adjusting parameter values in a set of equations. The goal is to ensure that the output of these equations accurately reflects observed sediment erosion and deposition behavior across a range of sediment sizes, from about 10 microns to about 10 centimeters. The method defines an initial condition of a sediment bed in the hydrocarbon reservoir and applies the equations to this condition. The outputs express how fluid flow impacts the erosion and deposition of sediments, allowing for adjustments to create subsequent sediment bed conditions. The equations are re-applied multiple times to refine the model of the hydrocarbon reservoir.

Another notable patent is the "Method for evaluating sedimentary basin properties by numerical modeling of sedimentation processes." This method involves simulating the formation of sedimentary deposits by solving a two-dimensional time-dependent system of equations. It calculates net sediment deposition at various locations and records the time-variability of this deposition, providing valuable insights into sedimentary processes.
