Latest Patents

One of his latest patents is a measuring process of dynamic viscosity of heavy live crude from the reservoir pressure up to atmospheric pressure, including bubble point pressure, based on an electromagnetic viscometer. The objective of this invention is to provide a reliable process for the experimental determination of heavy live crude oil dynamic viscosities at a constant temperature, ranging from ambient temperature to 463 K, and pressures from 68.9 MPa to atmospheric pressure. The apparatus utilized in this invention is based on an electromagnetic concept, employing a mobile element (piston) through a fluid at a constant force. The time required for the piston to travel a fixed distance is directly related to the dynamic viscosity of the fluid contained in a measuring chamber. When the fluid is more viscous, the piston displacement occurs at a slower rate.

Another significant patent involves geminal zwitterionic surfactants as wettability modifiers in enhanced oil recovery processes. This invention focuses on geminal zwitterionic surfactants based on bis-N-alkyl, bis-N-alkenyl, N-cycloalkyl, or N-aryl bis-beta amino acids or their salts. These surfactants serve as wettability modifiers for various types of rocks, including limestone, dolomite, sand, quartz, and heterogeneous lithologies.
