... charts of production data, the data will be compared with the current well model surface IPR data and the latest valid production test. Finally, to aid quality control of the production data, the sub-daily THP data will be used to calculate a model-derived flowrate based on pressure. The result...

.... This paper touches upon the outer boundary with constant rate, that is, the effect of multiple well system on testing well is reflected on the injection rate at the outer boundary of testing well, whose relation with the production rate of testing well is Injection-Production Ratio (IPR) of the drainage area...
