Abstract: Determining a Reservoir Management Factor™ (RMF™ or ?) for a petroleum producer provides a novel metric, selection, design, implementation and monitoring tool designed for use in implementing capital projects for increasing production and reserves of the petroleum producer. The RMF or ? can be determined according to the following equation: ?=sum of regression coefficients=sum of (reserves coefficient, production coefficient) wherein, reserves coefficient=the coefficient of the petroleum producer's reserves; and production coefficient=the coefficient of the petroleum producer's production. The producer can based on the RMF, select, design, implement and monitor one or more capital projects for increasing production and reserves of the petroleum producer. The capital projects can include drilling additional wells, stimulating existing wells, and increasing reservoir contact of existing wells.

Abstract: Determining a True Value Index™ (TVI™) for a petroleum production capital project provides a novel indicator and metric that is designed to quickly assess the economics of undertaking the petroleum production capital project. The TVI™ can be determined according to the following equation: TVI=NPV+(?*Reserves) where, NPV=Net present value of a project; ?=Reservoir Management Factor (RMF™)=absolute value (sum of Coefficient of Reserves and Coefficient of Production) derived from multivariable correlation=to reflect the market value premium on increased reserves if the producer was public; and Reserves=Barrels of proven reserves to be created by the project.

Abstract: The present invention is a method and apparatus for injecting compressible fluids into multiple zones of a hydrocarbon bearing formation, in particular injecting compressible fluid at a predetermined, constant rate into multiple zones through a single tubing string. Producing zones are packed off and limited entry outlets are installed on the injection tubing string at each producing zone. Injection pressure is maintained and limited entry outlets are designed and sized such that the compressible fluid reaches sonic flow through the outlets so that the flow rate no longer responds to changes in downstream pressures.
