Latest Patents
Calcar holds 1 patent for his invention titled "Gas kick detector - Methods for the early detection of gas kicks in marine risers." This patent outlines a system that includes monitoring a downhole absolute pressure and a downhole differential pressure of a riser section positioned just above the blowout preventer. The absolute pressure is utilized to calculate an average density of mud or a mud/gas mixture in the entire riser. The differential pressure across the riser section is then used to determine the average density of the mud or mud/gas mixture in that specific section. An unfavorable comparison between these calculated densities serves as an alert for the onset of a gas kick, thereby enhancing operational safety.
