Abstract: To detect the occurrence of slippage, a transmission health monitor integrates speed measurements for an engine shaft and a transmission shaft to determine a number of revolutions for each shaft. The monitor then uses a ratio of the revolutions adjusted for a transmission gear ratio to determine whether slippage has occurred. Based on the slippage, the monitor can determine a cumulative amount of wear on a clutch for each gear and track the rate of change of slippage over time to determine a rate at which wear is occurring. The monitor can also correlate slippage calculations with torque measurements to identify operating conditions at which slippage is occurring. The monitor uses the cumulative amount of slippage, the rate of change of slippage, and the operating conditions at which slippage is occurring to estimate a remaining lifespan for a clutch or indicate that a clutch should be repaired or replaced.

Abstract: System and methods of controlling fracture growth during multi-well stimulation treatments. The flow distribution of treatment fluid injected into first and second well formation entry points along multiple wellbores is monitored during a current stage of a multi-well, multistage stimulation treatment. Upon determining the fracture growth and/or monitored flow distribution meets a threshold, a remainder of the current stage is partitioned into a plurality of treatment cycles and at least one diversion phase. A portion of the fluid to be injected into the first well and/or second well formation entry points is allocated to each of the treatment cycles of the partitioned stage. The treatment cycles are performed for the remainder of the current stage using the treatment fluid allocated to each treatment cycle, wherein the flow distribution is adjusted so as not to meet the threshold.
