Patent number: 10983439Abstract: A method for fabricating calcite channels in a nanofluidic device is described. A photoresist is coated on a substrate, and a portion of the photoresist is then exposed to a beam of electrons in a channel pattern. The exposed portion of the photoresist is developed to form a channel pattern, and calcite is deposited in the channel pattern using a calcite precursor gas. The deposited calcite includes at least one side having a length in a range of approximately 50 to 100 nanometers. The photoresist remaining after developing the exposed portion of the photoresist is removed.Type: GrantFiled: April 25, 2019Date of Patent: April 20, 2021Assignee: Saudi Arabian Oil CompanyInventors: Dong Kyu Cha, Mohammed Al Otaibi, Ali Abdallah Al-Yousef

Patent number: 10948429Abstract: A process for the preparation and imaging of a sample of rock from an oil and gas reservoir is provided. A sample of reservoir rock may be obtained, such as from a core sample obtained using a core sampling tool inserted in a wellbore extending into an oil and gas reservoir. A photoresist may be deposited on the surface of reservoir rock sample to form a homogenous layer. The photoresist-coated surface of the reservoir rock sample may be imaged using a focused ion beam (FIB). The photoresist protects the pores and other surface features of the rock from damage or implantation by the FIB ion beam and thus minimizes the curtain effect in the resulting images.Type: GrantFiled: April 3, 2019Date of Patent: March 16, 2021Assignee: Saudi Arabian Oil CompanyInventors: Dong kyu Cha, Sultan Enezi, Mohammed Al Otaibi, Ali Abdallah Al-Yousef
