Claim:
1. An injection treatment control method comprising: receiving pressure response data from an injection test of a subterranean region during an injection treatment of the subterranean region, the pressure response data being acquired during a series of injection periods, wherein each successive injection period of the series is conducted at an increased injection rate with respect to the prior injection period of the series, and shut-in intervals of the injection test, each of the injection periods temporally followed by a respective one of the shut-in intervals, each of the shut-in intervals comprising shutting in a wellbore from which the injection test is applied for a specific duration of time, the pressure response data comprising respective pressure data corresponding to each of the series of injection periods and shut-in intervals; analyzing the pressure response data based on a combination of the respective pressure data corresponding to each of the series of injection periods and shut-in intervals, wherein analyzing the pressure response data comprises determining an effect of wellbore friction in the pressure response data based on the combination of the respective pressure response data corresponding to each of the series of injection periods and shut-in intervals, wherein determining an effect of the wellbore friction in the pressure response data based on the combination of the respective pressure response data comprises: modifying the injection treatment based on the analyzed pressure response data.
