Our company carries primary and control deliverability tests in oil and gas wells using memory pressure gauges.Gas well deliverability indicates the rate at which a gas well can produce at a given bottom hole or wellhead pressure. The application of deliverability testing is to generate a reservoir inflow performance relationship (IPR) or gas backpressure curve. The IPR curve describes the relationship between surface production rate and borehole flowing pressure for a specific value of reservoir pressure (that is, either the original pressure or the current average value). The IPR curve can be used to evaluate gas-well current deliverability potential under a variety of surface conditions, such as production against a fixed backpressure. Besides, the IPR can be used to forecast future production at any stage in the reservoir’s life. The gauge measures pressure and temperature at specified time intervals and records all data into internal storage.
