摘要： Systems and methods for determining the composition of a drilling fluid using electro-rheology may be provided. A method for drilling a wellbore may include: circulating a drilling fluid in a wellbore; extending the wellbore into one or more subterranean formations; measuring impedance of at least a portion of the drilling fluid over time as one or more particulate additives in the drilling fluid settle; determining one or more model elements of an equivalent circuit model for modeling frequency responses of the drilling fluid from the impedance; and determining sag behavior of the drilling fluid based, at least partially, on the one or more model elements.

摘要： Methods including precipitated and mined calcium carbonate lost circulation materials for use in subterranean formation operations. The precipitated calcium carbonate lost circulation materials are formed under a chosen set of precipitation conditions, including in situ in a subterranean formation. The mined calcium carbonate lost circulation materials are obtained in a desired morphological form under naturally occurring mined conditions. The precipitated and mined calcium carbonate lost circulation materials may be needle-shaped aragonite having an aspect ratio of about 1.4 to about 15.

摘要： A process control system can include a vessel, and at least one heat transfer property sensor that measures a heat transfer property of a substance at the vessel. The process control system can also include a monitoring device that receives an output of the heat transfer property sensor, and a process control device that is adjusted in response to the heat transfer property sensor output. A method of controlling a process can include measuring a thermal conductivity of a substance at a vessel, and adjusting the process in response to the measuring.

摘要： A system and method for rheology measurements. The system may comprise a conduit; an ultrasound transmitter positioned to direct ultrasound pulses into the conduit; an ultrasound receiver positioned to receive sound waves from the conduit; a pump fluidically coupled to the conduit; and a heat exchanger fluidically coupled to the conduit. The method may comprise drawing a sample of a treatment fluid into the rheology measurement system; pressuring the sample of the treatment fluid; adjusting temperature of the treatment fluid; directing ultrasound pulses into the treatment fluid while the treatment fluid is flowing through the rheology measurement system; measuring sound waves reflected by the treatment fluid; and determining a velocity profile of the treatment fluid based at least on the measured sound waves.

摘要： An apparatus including an electromagnetic radiation source that emits electromagnetic radiation, a sample chamber comprising a fluid sample inlet for introducing a solids-laden fluid sample therein, and a detector that receives a backscattering signal and generates an output signal corresponding to a concentration of solids in the solids-laden fluid sample. The electromagnetic radiation transmits through the sample chamber and optically interacts with the solids-laden fluid sample to generate a backscattering signal. The sample chamber may include one or more of a shear bob for applying a shear rate to the solids-laden fluid sample, the shear bob suspended in the sample chamber and rotatable about an axis, a sealable fluid pressurizing inlet for pressurizing the sample chamber and a pressure gauge for measuring the pressure in the sample chamber when pressurized, and/or a temperature source for heating the solids-laden fluid sample.

摘要： Thermal conductivity measurements of a wellbore fluid may be used to derive the sag of the wellbore fluid (i.e., the inhomogeneity or gradation in particle distribution in the fluid as a result of the particles settling). For example, a method may include measuring a thermal conductivity of a fluid at two or more locations along a height of a vessel containing the fluid that comprises particles dispersed in a base fluid; and calculating a sag of the fluid based on the thermal conductivity at the two or more locations. In some instances, the temperature and pressure of the wellbore fluid may be changed and/or the wellbore fluid may be sheared to investigate their effects on sag.
