Abstract: A system and method for predicting a specific aspect, such as run life, of a component or system. The system utilizes a variety of complexity index values that are assigned to each component of the system. Each complexity index value is determined according to select physical parameters of the component. The summing of the complexity index values provides a system complexity index value that can be used to accurately estimate, for example, the run life of the system.

Abstract: A packer is disposed within a wellbore casing. The packer defines a first and a second zone of the wellbore. A submersible pumping system is used to displace liquid from the first zone of the wellbore via a first fluid flow path. A cable is used for supplying power to the submersible pumping system. The cable extends through tubing that extends from a surface location. A second fluid flow path extends from the first zone of the wellbore to a surface location. A portion of the second fluid flow path extends through the tubing.

Abstract: A technique is provided for supplying electrical power to a submersible pumping system in a well completion. The pumping system includes a submersible electric motor, a pump driven by the motor and a separator for separating liquid and gas phase components of the wellbore fluids. The gas phase components are produced through a first passageway in an isolating packer, with liquid phase components being produced through a separate passageway through the packer. A transition assembly, including a connector adapter is provided in either the liquid or gas flow path, and either on the lower or upper side of the packer. The transition assembly incorporates a connector for securing upper and lower cable portions to one another. The lower cable portion extends from the connector to the electric motor, while the upper cable assembly extends from the connector to the earth's surface.

Abstract: A technique is described for producing fluids from a series of wells. Production fluids from production wells are raised from the wells and deposited in a collection well. The production fluids may include both liquid and gas phase components. The collection well may serve to permit separation of the gas and liquid phase components under the forces of gravity. The fluids deposited in the collection well are separately displaced to a further collection and processing location. The head requirements for the pumping systems of the production wells is reduced by the need only to transmit the production fluids to the collection well. A pumping system in the collection well then produces some or all of the deposited fluids. Where the fluids include significant quantities of gas, the collection well pumping system may only produce the liquid-phase components, reducing the capacity requirements for the collection well pumping system.

Abstract: A technique is disclosed for completion of a well, such as an oil and gas production well. A packer is positioned in the well to divide the well into upper and lower zones. The packer has multiple passageways between the upper and lower zones. A pumping system is positioned in the lower zone for displacing wellbore fluids flowing from a production formation. The pumping system may include a liquid/gas separator, and express gas-phase components through one of the passageways and liquid-phase components through another. A conduit conveys the gas-phase components to a desired location. The liquid-phase components are conveyed to a collection location in the annular region surrounding the conduit. The conduit may be used for positioning a chemical injection line within the well, or for receiving a parameter sensing unit. The chemical injection and parameter sensing may be performed independently of gas production, and without interruption of either gas or liquid production.
