An automated drilling-fluid additive system and method for on-site real-time analysis and additive treatment of drilling fluid to be injected into a well. The drilling fluid includes returned drilling fluid intended to be re-used, which has a variety of viscosity and other qualities resulting from its various preceding use. The target drilling fluid will have a variety of viscosity and other qualities depending upon and changing with various phases of drilling operations and various conditions encountered. The drilling fluid is analyzed in real time as it flows into the automated drilling-fluid additive system, and various additives are added to and thoroughly blended with the drilling fluid as needed to achieve the desired result. The blended drilling fluid is discharged from the automated drilling-fluid additive system in the proper condition for injection into a well.

A distribution tube for a static mixer provides efficient mixing with improved performance over a wide range of flow rates. The distribution tube is positioned near an inlet side of the static mixer. An injected fluid is introduced into the static mixer via the distribution tube, which pre-mixes the injected fluid with a main fluid prior to further mixing by mixing elements of the static mixer.

The present disclosure provides a microchannel device including a first base having a defining surface that defines a flow channel and containing a polymer that contains a fluorine atom and a second base having a defining surface that defines the flow channel together with the defining surface of the first base, having solvent resistance, and coming into contact with the first base, in which an arithmetic average roughness Ra of a surface of the first base, exposed by peeling the second base from the first base, is 1 μm or more, and provides a use application thereof.

A mixing chamber is loaded with a first fluid. While a volume of the first fluid within the mixing chamber is constant, first and second streams of a second fluid are injected into the mixing chamber along first and second injection directions. As a result of injecting the first and second streams of the second fluid into the mixing chamber, the first and second streams of the second fluid impinge one another so as to generate within the mixing chamber at least one further stream of the second fluid that mixes with the first fluid and that flows in a direction different to the first and second injection directions.

Disclosed herein are systems and methods for serial flow emulsion processes. Systems and methods as described herein result in reduced cross-contamination.

Devices, systems, and their methods of use, for generating droplets are provided. One or more geometric parameters of a microfluidic channel can be selected to generate droplets of a desired and predictable droplet size.

The mixing nozzle has a throat section, a diffuser section, a gas nozzle section, a first liquid suction port, a liquid nozzle section, a second liquid suction port, a baffle plate, and a jetting port. The first liquid suction port liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section toward the gas nozzle tip. The liquid nozzle section extends to the downstream side of the gas nozzle section with intervening the first liquid suction port. The second liquid suction port liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section toward the liquid nozzle tip. The baffle plate is provided such that the mixed flow mixed in the diffuser section collides in front of a downstream end of the diffuser section, and divides and reverses the mixed flow.

A method of hydraulic fracturing of an oil producing formation includes the provision of a heating apparatus which is transportable and that has a vessel for containing water. A water stream of cool or cold water is transmitted from a source to a means for increasing the temperature of the cool or cold water, the cool or cold water stream being at ambient temperature. The means for increasing the temperature of the cool or cold water has an inlet that receives cool or cold water from the source and an outlet that enables a discharge of a mix of cool or cold water and the hot water. After mixing in the means for increasing the temperature of the cool or cold water, the water assumes a temperature that is suitable for mixing with chemicals that are used in the fracturing process, such as a temperature of about 40°-120° F.+ (4.4° - 48.9° C.+). An outlet discharges a mix of the cool or cold and hot water to tanks. In the mixing tanks, a proppant and an optional selected chemical or chemicals are added to the water which has been warmed. From the tanks, the water with proppant and optional chemicals is injected into the well for part of the hydraulic fracturing operation.
