A method for testing producing oil and gas wells is disclosed for determining a representation of pressure at different selected levels of an interval having one or more production zones by combining pressure and pressure gradient measurements. Another aspect of the invention enables the determination of production level performance by combining flow measurements and pressure gradient measurements to create pressure versus flow curves for each production level of an interval.

A well test method for determining a represenation of the pressures in a well at different selected levels of an interval having one or more production zones, comprising the following steps: making pressure gradient measurements in the well along the interval of the well; making at least one stationary meaurement of the local pressure in the well at a depth in the interval; and combining the pressure gradient measurements and the said at least one stationary local pressure measurement by integrating the variations of the pressure gradient measurements along the interval to obtain a first pressure-variation profile and shifting the first profile until the best coincidence is obtained with the at least one stationary local pressure measurement to determine the pressure profile of the well along the interval.
