PremiumPort is a patented downhole adjustable injection and inflow control technology. Its unique valve and port system allows operators to dynamically manage the pressure profile along horizontal wells in order to drive optimum well performance. Multiple PremiumPort units can be deployed along the lateral to manage complex reservoir intervals along extended laterals. The valve and port system can be actuated repeatedly for a variety of production and injection operations over the life of the well.
The valve can be shifted to activate ports in any order, with manipulation time of approximately 30 seconds. A full bore unrestricted ID greater than the liner drift ID creates a large flow through area to accommodate high flow rates and future remedial well operations.Contact Us »
PremiumPort consists of a multi-position valve integrated with either two or three ports, which can be left as simple openings, or configured with nozzles for flow control applications. Using reservoir modelling, ports can be fitted at the wellsite with a nozzle (ICD) suitable for either injection or inflow control. The Harrier™ shifting tool, run on coil tubing, is used to shift the position of the valve to expose different port configurations.
The figure below shows FacsRite sand control (section of black on the left, with discs of media) integrated to the PremiumPort tool (middle blue) with its multi-position valve (right black) shifted to the right to expose the inflow control nozzles (small orange) at the end of the flow path from the sand control media.
Drilling extended reach lateral wells to access more reservoir area is now a common industry practice. Long horizontal wells encounter widely varying formation characteristics. Different zones along the lateral contribute differently to overall well productivity and may even be thief zones absorbing fluids instead of allowing them to be produced into the well bore.
The formation characteristics can change as the well ages, leading to water influx and sand influx which can be costly to remediate. When remediation fails the operator may face catastrophic failure of the well long before optimum reserve recovery as been possible. For all of these reasons, operators need innovative completion strategies that are designed to allow different techniques to be applied during liner deployment, initial production, and as the well ages.
With PremiumPort, shifting the position of the full-bore valve sets the ports to be either closed, open, or a combination of open/closed. Applications can include:
PremiumPort can be configured with a variety of nozzle styles:
CrossFlow – for horizontal wells with high production or injection rates, vertical wells in consolidated formations with commingled zones of different pressures, and for high temperature steam or water injection
SecureFlow – for cyclic steam, SAGD heavy oil, high pressure gas production wells and high pressure steam or water injection
StandardFlow – for moderate flow rate, moderate pressure wells with no downhole

Reliable Valve Operation
The dependable operation of PremiumPort’s multi-position valve is based on a unique
Reliable Seal Function
The proprietary seal design maintains the integrity of the interior of the valve thus ensuring consistent, reliable and safe operation during multiple manipulations over the life of a well. The seal design eliminates the risks of seal washout from sudden high pressure differentials, or seal erosion by solids during opening, closing or stimulation operations.
Reliable Nozzle Operation
Nozzles installed in ports for inflow or injection control are made of tungsten carbide and may also be coated with titanium nitride for maximum erosion and corrosion resistance. Each flow port and/or nozzle is isolated by the proprietary seal design.
PremiumPort can be used to improve the performance of multi-zone vertical as well as horizontal wells. The valve positions can be selected in any order and any sequence depending on the operational program, production results, and life cycle of the well.
Each valve in a PremiumPort completion can accommodate a unique, sacrificial bio-tracer which will provide surface indication of the oil-water influx from each valve position and zone.
Single or multiple PremiumPort valves can be economically placed within each wellbore segment providing flexible port options to control flow, water coning, and to allow repeated clean up, and stimulations over the life of the well:
The valve can be shifted to activate ports in any order, with manipulation time of approximately 30 seconds. A fullbore unrestricted ID greater than the liner drift ID creates a large flow through area to accommodate high flow rates and
future remedial well operations.
Multiple PremiumPort tools can be integrated with sections of a sand control screen for dynamically adjustable flow control along the lateral as required.
