Publication number: 20200407619Abstract: A rapidly dehydrating lost circulation material (LCM) composition is provided. The LCM composition may include a carrier fluid, diatomaceous earth, a viscosifier, and date tree rachis fibers. The carrier fluid may be water and the viscosifier may be a cellulosic microfiber. The LCM composition may form a rapidly dehydrating loss control slurry (RDLCS). The LCM composition may be formed by mixing the carrier fluid, the diatomaceous earth, the viscosifier, and the date tree rachis fibers in a mixer to form a homogenous mixture. Methods of lost circulation control and manufacture of a rapidly dehydrating LCM are also provided.Type: ApplicationFiled: August 26, 2020Publication date: December 31, 2020Inventor: Md Amanullah

Publication number: 20200407621Abstract: Drilling fluids and methods of making and using drilling fluids are provided. The drilling fluid contains an aqueous phase, an oleaginous phase, and at least one surfactant having the formula R—(OC2H4)x—OH, where R is a hydrocarbyl group having from 8 to 20 carbon atoms and x is an integer from 1 to 10. Methods of producing drilling fluids include mixing an aqueous phase, an oleaginous phase, and at least one surfactant, and shearing the mixture. Methods of using drilling fluids to drill subterranean formations include mixing an aqueous phase, an oleaginous phase, and at least one surfactant to produce a mixture, which is sheared to form a drilling fluid, and pumped through a drill string in a drill bit located in a subterranean formation. Rock cuttings are transported from the drill bit to a surface of the subterranean formation and the drilling fluid is circulated in the subterranean formation.Type: ApplicationFiled: September 10, 2020Publication date: December 31, 2020Applicant: Saudi Arabian Oil CompanyInventors: Abdullah Al-Yami, Vikrant Wagle, Hussain AlBahrani, Ali Safran, Nasser AlHareth

Publication number: 20200407622Abstract: Described herein are compositions useful for controlling fluid flow, for example in a target zone of a subterranean environment, and methods of forming and using the same. The composition generally comprises a quantity of fibers and a quantity of swellable particles, which may be dispersed in a carrier fluid. The composition may be synthesized in the form of a bulk gel or may be gelatinated during use. The fibers in the compositions provide improved performance as compared to prior PPG and RPPG particle-containing compositions. Specifically, the compositions reinforce the re-cross-linked/re-associated hydrogel plug in underground features and support proper rehydration of RPPG particles with water or brine to better to provide structural support for the particles within the gel and to more completely fill underground void space conduits.Type: ApplicationFiled: September 8, 2020Publication date: December 31, 2020Inventors: Baojun Bai, Ze Wang, Zhe Sun, Jingyang Pu, Thomas Schuman

Publication number: 20200407625Abstract: Systems and methods are provided for overpressure mitigation or prevention in a well system. The overpressure mitigation systems and methods obtain downhole pressure measurements using a downhole pressure sensor. A rate of change of the downhole pressure is determined based on the downhole pressure measurements, and the rate of change is compared with a rate-of-change threshold. The rate-of-change threshold is determined uniquely for each well system in real time based on a flow rate of the fluid, a volume of the fluid, a proppant concentration in the fluid, a speed of sound in the fluid, and/or other features of the fluid, the proppant, the wellbore, a casing, or other components of the well system.Type: ApplicationFiled: December 12, 2017Publication date: December 31, 2020Inventor: Stanley V. STEPHENSON
