A well test that involves recording pressure versus time to determine how flow rates influence pressure behavior measured in a well. Mathematical relationships between flow rate, pressure and time are applied to data to infer properties and conditions of the well and reservoir. 3. 2017 GWPC UIC Conference. STEP RATE TEST The following is an example of a Step-Rate Test with tabular and graphic results. The step-rate test data and graphic results of the test are on the following pages. The operator of Anywell #1 set up a SRT for the following conditions: A) Maximum anticipated injection rate was 4 bbl/min. Step Down Test Analysis This type of analysis is performed prior to a main frac job. It is used to quantify perforation and near-wellbore pressure losses (caused by tortuosity) of frac'd wells, and as a result, provides information pertinent to the design and execution of the main frac treatments. step rate test. 1. n. [Well Completions] A test performed in preparation for a hydraulic fracturing treatment in which an injection fluid is injected for a defined period in a series of increasing pump rates. Calculated permeability from step-rate test is 113the mD for a 30 ft interval that is in vertical communication based on vertical permeability and Lorenz plot (fig. 11) ;where, results of flow units and flow capacity ( 𝛴𝛴𝛴𝛴ℎ%) are shown in fig ure 12. Calculated permeability from the analysis One such test is the "step-up?? step-rate test. In this test, injection into a formation is begun at a slow rate for a fixed amount of time, and the rate is then increased and again held for the same amount of time. This is repeated in an attempt to achieve three matrix injection rates and three fracture injection rates. My max heart rate is 190, which is a lot more that obsolete 200-age formula is giving to my age (48), i exercise regularly at 175 bpm without any effort. During step test ( i have monitor now) my HR would raise to 160 and then drop 20+ points in minute, yet 3 step test is giving very poor score to may age. How i can trust it? Report

The methods of analysis and the criteria for planning step drawdown tests are discussed and evaluated in order to produce an optimum test programme and a comprehensive test analysis. Step drawdown tests can be used to determine the aquifer transmissivity and the well loss component of the drawdown in the pumped well. Step rate test S3 from instanteneous shut in pressure Surface pressure versus elapsed time Leak off test (mini frac, FIT,XLOT) LT: Limit test LOP: Leak-off p purpose: a step test provides a submaximal measure of cardio-respiratory or endurance fitness (see also other step tests) equipment required: 12 inch (30 cm) step, stopwatch , metronome or cadence tape, stethoscope. Fig. 1 shows an example in which the transient consists of a step-rate change from a high value with a downhole spinner flowmeter rotation rate of approximately 17 revolutions per second (rps) to a lower value with a flowmeter response of approximately 7 rps. Clearly, the pressure and flow-rate data mirror each other, which is precisely the effect of the convolution.

To enhance the usefulness of step-rate test data, the current paper describes a new method of analysis that also determines the injectivity index of the well and fracture, the fracture length, width and effective leak-off rate. Injectivity analysis provides additional formation data which is useful for fracture designs, formation evaluation and optimizing water injection rates.
