Abstract
In a multiple well completion, spaced apart production packers isolate independent production zones from one another. In each isolated production zone, a side pocket mandrel with a full opening bore has lengthwise extending side by side elongated pockets (1) for receiving a static pressure measuring instrument or tool (static pressure pocket); (2) for providing a venturi flow passageway (flow passageway pocket); and (3) for receiving a differential pressure measuring tool (differential pressure pocket). The static pressure measuring tool and the differential pressure measuring tool or instrument are commonly connected by a data coupling means to a single electrical conductor line which is strapped to the string of tubing and extends to the earth's surface for transmission of control signals and data signals between the earth's surface and the various side pocket tools. The venturi flow passageway is connected for fluid communication with the static pressure pocket and the differential pressure pocket in the side pocket mandrel. Fluid flow from a particular production zone is channeled through the respective venturi flow passageway to the full opening bore and the fluid flow parameters are communicated to the static pressure measuring tool and to the differential pressure tool. The flow passageway is constructed and arranged to develop a differential pressure which is measured by the differential pressure measuring tool. At the same time, the static pressure of the production fluid in the production zone is measured by the static pressure measuring tool. Both the differential pressure measurements and the static pressure measurements may be transmitted to the surface and recorded as a function of real time.
