Patent number: 11941128Abstract: A liquid additive mixing apparatus is provided that has a plurality of chambers containing additives, as well as a system for mixing the additives. One or more additives are mixed with water to form a mixing fluid. The mixing fluid is placed in a first tank that is fluidly connected to a cement mixing unit. A cementing operation is executed during which the mixing fluid from the first tank is mixed with a cement to form a slurry. A capillary electrophoresis (CE) instrument is employed to monitor at least one additive parameter and detect deviations from a predetermined tolerance for the at least one additive parameter.Type: GrantFiled: March 28, 2018Date of Patent: March 26, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Simon Ivar Andersen, Sharath Chandra Mahavadi, Salim Taoutaou, Alexander Nebesnyy, Jonathan Wun Shiung Chong

Patent number: 11761873Abstract: Methods may include emplacing a downhole tool within a wellbore, sampling a fluid downhole with the downhole tool; analyzing the fluid, and calculating an interfacial tension (IFT), wherein calculating the acid-base IFT contribution comprises measuring a concentration of a surface-active species directly. Apparatuses for measuring an interfacial tension (IFT) in a fluid downhole may be part of a downhole tool and may include a sampling head to sample the fluid; and a downhole fluid analysis module that includes a spectrometer capable of measuring a concentration of a surface-active species in the fluid, and a processor configured to determine the IFT of the fluid downhole based on the measured concentration of the surface-active species.Type: GrantFiled: December 14, 2017Date of Patent: September 19, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Simon Ivar Andersen, Wael Abdallah, Dominic Joseph Brady, Mohammed Badri, Sharath Chandra Mahavadi, Bastian Sauerer, Mohamed Ahmed Abdel Reheem Hamdy

Patent number: 11754546Abstract: Systems and methods for monitoring a crude oil blending process use nuclear magnetic resonance (NMR) sensors which investigate properties of a plurality of crude oil streams that are mixed together to form a crude oil blend. An NMR sensor is also used to investigate the properties of the crude oil blend. The investigated properties may include viscosity. Resulting determinations may be used to control the input streams so that the output stream meets desired criteria. Additional sensors such as spectroscopy sensors, viscometers, and densitometers may be used in conjunction with the NMR sensors.Type: GrantFiled: December 10, 2018Date of Patent: September 12, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sharath Chandra Mahavadi, Ravinath Kausik Kadayam Viswanathan, Kamilla Fellah, Simon Ivar Andersen, Yiqiao Tang, Yi-Qiao Song, Shawn David Taylor, Gary Potten

Patent number: 11169114Abstract: The current application discloses methods and systems to analyze on-site and in real-time or quasi real-time the composition of the well fluid before or during use or disposition. The method is based on capillary electrophoresis (CE) and does not require the addition of tracers into the well fluid or additive. Based on the significance of each additive on the well fluid properties, it can be decided to determine the concentration of all additives or only one or a limited number of the additives present in the fluid, and the concentrations can be adjusted as needed to reach the desired target concentration(s).Type: GrantFiled: January 20, 2015Date of Patent: November 9, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sharath Chandra Mahavadi, Simon Ivar Andersen, Olivier Porcherie, Isabelle Couillet

Patent number: 10031122Abstract: A method and apparatus for analyzing solubility of asphaltenes of a hydrocarbon fluid sample involves a sequence of operations including: i) performing microfluidic mixing operations that form a mixture that includes the hydrocarbon fluid sample, a solvent that dissolves asphaltenes and a precipitant that precipitates asphaltenes; ii) using microfluidic processes that result in precipitation of asphaltenes from the mixture resulting from i); iii) performing microfluidic filtering operations that remove precipitated asphaltenes resulting from ii) and passes permeate; and iv) performing optical spectroscopy on the permeate resulting from iii). The operations of i)-iv) can be repeated over iterations that vary the amount of solvent relative to the precipitant in the mixture. These iterations can cause varying fractional precipitation of asphaltenes in each given iteration.Type: GrantFiled: May 28, 2014Date of Patent: July 24, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Vincent Joseph Sieben, Simon Ivar Andersen, Farshid Mostowfi, Abdel M.
