Title: Innovations by Marco Rasi in Drilling Technology
Introduction
Marco Rasi is an accomplished inventor based in Houston, TX, known for his significant contributions to drilling technology. He holds a total of 3 patents that focus on improving drilling efficiency and reducing risks associated with drilling operations. His work is particularly relevant in the oil and gas industry, where precision and reliability are paramount.
Latest Patents
One of Marco Rasi's latest patents is a method to combine statistical and engineering techniques for stuck pipe. This invention provides a comprehensive approach to modeling the probability of a drill string becoming stuck within a specified time frame. By utilizing canonical discriminant analysis on engineering parameters derived from historical well observations, Rasi's method creates a canonical space that allows for the calculation of posterior probabilities of sticking. This model can be applied to ongoing drilling operations to mitigate the risk of sticking by implementing remedial measures based on historical data.
Another notable patent is the method of controlling cuttings accumulation in high-angle wells. This method predicts the area of open region above a bed of cuttings resulting from drilling a high-angle well. By comparing the area of the bit used in drilling with the area of the open region and drill pipe, Rasi establishes a Hole-Cleaning Ratio. This ratio is then correlated with past occurrences of drilling problems to predict risks in future wells, allowing for proactive adjustments during drilling operations.
