    Abstract: A method of receiving a plurality of oilfield brine feedstocks from one or more producing wells producing hydrocarbons from a subterranean formation is provided. The method includes detecting, using one or more sensors, one or more properties of the plurality of oilfield brine feedstocks, selecting two or more oilfield brine feedstocks from the plurality based at least in part on the one or more properties of the plurality of oilfield brine feedstocks, blending the two or more oilfield brine feedstocks into a blended oilfield brine prior to desalinating and crystallizing a portion of the blended oilfield brine, desalinating and crystallizing the portion of the blended oilfield brine to produce desalinated water and a salt slurry suspension, selecting one or more candidate wells for reinjection of the salt slurry suspension into the one or more candidate wells, and reinjecting the salt slurry suspension into the one or more candidate wells.

    Abstract: A method includes placing a fluid in a treatment zone of a wellbore, the fluid in fluid communication with a near wellbore region of a subterranean formation. At least one energetic event generating material is placed in the wellbore, and positioned adjacent and up hole from the fluid. An energetic event is generated from the at least one energetic event generating material, and at least one fracture is formed in the near wellbore region from the at least one energetic event applying a pressure pulse onto the fluid. In some aspects, the fluid is a viscous pill.

    Abstract: A method is given for treating a wellbore in a subterranean formation by hydraulic fracturing, slickwater fracturing, gravel packing, and the like, by using plate-like materials as some or all of the proppant or gravel. The plate-like materials are particularly useful in complex fracture systems, for example in shales. They may be used as from about 20 to about 100% of the proppant. Relative to conventional proppants, plate-like proppants demonstrate (a) enhanced crush resistance of the proppant due to better stress distribution among proppant particles, (b) diminished proppant embedment into formation fracture faces due to the greater contact surface area of proppant particles with the formation, (c) better proppant transport due to lower proppant settling rates, (d) deeper penetration into branched and fine fracture networks, and (e) enhanced proppant flowback control. Preferred plate-like proppants are layered rocks and minerals; most preferred is mica.

    Abstract: A method for determining a characteristic of an underground formation with a fluid is described. The method includes providing a sample material of the underground formation; measuring the permeability and the porosity of the sample material; performing a drainage test on the sample material using the fluid; estimating the threshold pressure of the sample material from the drainage test, the permeability and the porosity measurements; and determining the receding contact angle of the fluid on the sample material from the threshold pressure. The sample material can be disaggregated material.
