Patent number: 10351756Abstract: Organoclay is used as an alternative emulsifier and reinforcing agent to enhance the strength of emulsified polymeric gel aqueous solutions and form water in oil emulsions. The stability of the emulsion can be controlled by controlling salinity and the intensity of initial mixing. The new system can be used for water shut-off treatments as well as a relative permeability modifier in high water permeability zones. In addition, the system can tolerate salts much better than classical surfactants. This system will be appropriate for wellbores having high temperature (>85° C.) with harsh environmental conditions.Type: GrantFiled: March 12, 2018Date of Patent: July 16, 2019Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Ibnelwaleed Ali Hussein, Ahmad Akanbi Adewunmi, Abdullah Saad Sultan, Khalid Saad Elkarsani, Ghaithan A.

Patent number: 10138715Abstract: A well-bore monitoring process involving logging the temperature of a soil, rock, and brine mixture present in a carbonate formation continuously, and simultaneously logging the resistivity of the soil, rock, and brine mixture in the carbonate formation continuously. The logged temperature and the logged resistivity are interpreted whereby concurrent events in the logged temperature and the logged resistivity identify dissolution of rock into the mixture and precipitation of scale from the mixture. The simultaneous logging of the temperature and the resistivity is conducted in a well-bore in the carbonate rock formation.Type: GrantFiled: September 16, 2015Date of Patent: November 27, 2018Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Abdulrauf Rasheed Adebayo, Hasan Yousef Al-Yousef, Mohamed Mahmoud, Abdullah Saad Sultan

Patent number: 10081574Abstract: Method of converting calcium bentonite to sodium bentonite that is suitable for use as drilling mud or a cement additive. After the addition of a calcium bentonite sample to a prepared soda ash solution at predetermined soda ash/bentonite weight ratios, the bentonite suspension is continuously heated and stirred for up to 24 h. The heating and stirring are crucial towards enhancing the sodium activation of the bentonite, as well as other rheological properties of the bentonite.Type: GrantFiled: May 5, 2017Date of Patent: September 25, 2018Assignee: King Fahd University of Petroleum and MineralsInventors: Musaab Ibrahim Magzoub, Mustafa Saleh Nasser, Ibnelwaleed Ali Hussein, Mohamed Ahmed Nasr Eldin Mahmoud, Abdullah Saad Sultan

Publication number: 20150000916Abstract: The enhanced oil recovery using seawater and EDTA (ethylenediaminetetraacetic acid) is a method that uses injection of EDTA in seawater to enhance the recovery of oil from sandstone reservoirs. The EDTA may be introduced into seawater during the initial extraction of oil from the reservoir by seawater injection, or a solution of EDTA in seawater may be used to flush residual oil from the reservoir after the initial extraction by seawater injection. In either case, the EDTA is present in about 1.0 wt % to about 5.0 wt % of the seawater solution, and the solution has a pH of between 10.5 and 11.0.Type: ApplicationFiled: July 1, 2013Publication date: January 1, 2015Inventors: Mohamed Ahmed Nasr El-Din Mahmoud, HASAN SALMAN AL-HASHIM, ABDULLAH SAAD SULTAN, MOHAMMED ATTIA GADALLAH

Publication number: 20140338903Abstract: The method for enhanced oil recovery by in situ carbon dioxide generation utilizes a chelating fluid injected into an oil reservoir through a fluid injection system. The chelating fluid is a low pH solution of a polyamino carboxylic acid chelating agent. The polyamino carboxylic acid chelating agent may have a concentration of about 5 wt %. The polyamino carboxylic acid chelating agent is preferably either an aqueous solution of H2Na2-ethylenediaminetetraacetic acid (pH 4.5), H3-hydroxyethyl ethylenediamine triacetic acid (pH 2.5), or an aqueous solution of H2NaHEDTA (pH 4). The injection of the chelating fluid may be preceded by flooding the core with seawater, and is followed by injection of either to seawater, a high pH chelating agent, or low salinity water to ensure maximal extraction of oil from the reservoir. The method is particularly for use in formations where the core of the reservoir has a carbonate rock matrix.Type: ApplicationFiled: May 20, 2013Publication date: November 20, 2014Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: MOHAMED AHMED NASR EL-DIN MAHMOUD, ABDULLAH SAAD SULTAN, KHALED ZIDAN ABDELGAWAD
