Abstract: Systems and methods presented herein relate to processing produced oilfield brine by deconstructing it into two useful components: (1) desalinated water and (2) a suspension of solid state salt (e.g., crystallized salt) slurried in a salt saturated brine, which may be formulated and injected into hydrocarbon producing for mations above hydraulic fracturing pressure to intentionally create regions of localized high stress within the respective formations. In addition, systems and methods presented herein relate to processing oilfield brine received from hydrocarbon producing wells by : (1) coupling high pressure desalination technologies with saltwater disposal (SWD) operations, (2) active management of SWD water composition at the rock face through dual stream (e.g., split stream) injection, and /or (3) coupled SWD injection, flow assurance, and stimulation to minimize SWD formation damage and injection pressures.

Abstract: Apparatus and methods for measuring backlash of a gear train of a pump unit for pumping a fluid. An example method may include locking a crankshaft of the pump unit such that the crankshaft cannot rotate. The method may further include commencing operation of a processing device to receive rotational position measurements indicative of rotational position of an output shaft of a prime mover, cause the prime mover to rotate the output shaft in a first direction until the output shaft reaches a first rotational position, and cause the prime mover to rotate the output shaft in a second direction until the output shaft reaches a second rotational position. The processing device may then determine backlash of the gear train by determining rotational distance between the first rotational position of the output shaft and the second rotational position of the output shaft.
