Patent number: 10457863Abstract: The present invention refers to the formulation of a foaming agent for extreme conditions of salinity, temperature and concentration of divalent ions, including the improvement in the performance in these conditions with respect to the patent MX2008015989 A. Also, the design is presented of the experimental equipment used to characterize and evaluate foaming agents at laboratory level and conditions of pressure, temperature and salinity, in oil fields. The formulation of the foaming agent derived from this invention is a mixture of sodium alpha olefin sulfonates, alkylamido propyl betaines and triethanolamine, capable of giving it the benefit of being stable in temperature and salinity in a wide range, diluted in synthetic and congenital brines. This formulation is applicable for the control of gas mobility and improved oil recovery processes in naturally fractured reservoirs.Type: GrantFiled: December 13, 2017Date of Patent: October 29, 2019Assignee: INSTITUTO MEXICANO DEL PETRÓLEOInventors: Alejandro Ortega Rodríguez, Norma Araceli García Muñoz, José Manuel Martínez Magadán, Raúl Oviedo Roa, Sonia Ángeles Martínez Reyes, Marco Antonio Vélez Domínguez, Maribel Amador Ramírez, Ana Patricia Medina Montiel, Nansy Mónica Sánchez Casas, Elizabeth Cervantes Flores, Agustín Durán Álvarez, Simón López Ramírez, Cecilia de los Ángeles Durán Valencia

Patent number: 9255871Abstract: The object of the present invention is to provide a process for experimental determination of heavy live crude oil dynamic viscosities reliable at a constant temperature (from ambient temperature to 463 K) and pressures from 68.9 MPa to the atmospheric pressure, including the dynamic viscosity at the bubble point pressure and by below of this point, based on a simple, reliable and accurate apparatus. The apparatus used in the present invention is based on an electromagnetic concept, only using a mobile element (piston) through a fluid at a constant force. The time required for the piston to travel a fixed distance is related exactly to the dynamic viscosity of the fluid contained in a measuring chamber. When the fluid contained in the inner part of the measuring chamber is more viscous, the piston displacement will be slower.Type: GrantFiled: March 27, 2012Date of Patent: February 9, 2016Assignee: Instituto Mexicano Del PetroleoInventors: José Luis Mendoza De La Cruz, Roberto Carlos Ruiz Ortega, Cecilia de los Ángeles Durán Valencia, Simón López Ramírez, Alfredo Ríos Reyes, Oscar Orozco Caballero, Luis Manuel Pizano Gallardo
