Innovus™ Convertible Frac Sleeve
Geothermal Solutions

The Innovus™ Convertible Frac Sleeve features a dual inner barrel and can be converted post-frac or post-production for regulated water-injection using the Torius™ regulator.

This enhanced functionality allows geothermal well operators to optimize geothermal heat extration from injector / producer well pairs by regulating and optimizing flow. This helps to avoid “cold circuits” and inject evenly between injector and producer wells.

Additionally, the ability to open and close all stages at once allows for simplified remediation operations and to assess individual frac stages for flow performance.

Features and Benefits:

  • Special-purpose sleeve with a dual inner barrel
  • Can be deployed in cemented or open hole applications
  • Injection regulated by a calibrated tortuous flow path
  • Deployed on coiled tubing or jointed pipe
  • No pumpdown plugs or balls required

  • Supports frac rates up to 80 bbl/min (12.7 m3/min)
  • Sleeve make-up length is 40 in (101.6 cm) or less
  • Allows frac-port spacing as close as 15 ft (4.6 m)
  • Compact and easy to handle
  • No pup joints required for API
  • No pup joints needed for standard BTC or LTC thread types
  • Sleeves can be torqued through
  • Sleeves can be installed in any order
  • Proven for stage-by-stage wellbore management

  • Operated by the Innovus™ frac-isolation assembly
Terrus™ Injection Control Systems
Geothermal Solutions

The Terrus™ Injection Control System provides retrofit wellbore segmentation for regulated water-injection using the ultra-durable Torius™ Regulators.

Unlike bullheading or conventional injection-control-devices (ICDs), Terrus systems have options that allow individual zone injection to be adjusted post installation, individual zone shut off, and pressure-activated valves to eliminate the cost of initial intervention.

Further, the field proven Torius Regulator resolves the plug-off, washout, erosion and corrosion deficiencies that limit the performance and useful life of alternate systems.

This enhanced functionality and long-term performance allows geothermal well operators to optimize geothermal heat extraction from injector / producer well pairs by regulating and optimizing flow. Helping to avoid “cold circuits” and inject evenly between injector and producer wells.

Features and Benefits:

  • Provides retrofit wellbore segmentation and injection regulation
  • Controlled injection distribution to prevent “cold circuits” and maximize heat extraction
  • Mitigates plug-off, washout, erosion and corrosion
  • Designed for long-term use cases
  • Deployed on production tubing
  • Reliable-release compartment isolation packers for system retrieval if required
Proppex™ Frac Sleeve
Geothermal Solutions

Proppex™ was designed to keep proppant and unconsolidated formation sand where it’s supposed to be, on the outside of your geothermal wellbore.

After installing your next-generation geothermal completion system, you have the ability to stimulate the formation through the wide open ports in “open” mode.

When it’s time for production, Proppex™ can be shifted into “screen” mode to prevent unwanted sand and debris from entering the casing.

Features and Benefits:

  • Screen size is customizable
  • Compatible with cemented or open-hole completion strings.
  • Normal pinpoint fracture operations can be performed
  • Post frac, the FIA shifts into screen mode to prevent flowback
Tracer Diagnostics and Data Modeling

Tracer Diagnostics (TD) help our customers make better wells by verifying and measuring zonal contribution along the wellbore and evaluate connectivity and complexity between well pairs and / or offset wells. This information and data analysis helps identify key reservoir features and provides invaluable insight when making important development decisions.

In geothermal operations, especially in applications where similar stimulations from oil and gas are applied, tracer diagnostics offers:

  • Simulation fluid recovery analysis
  • Wellbore flow assurance via FFI liquid tracer deployment
  • Produced oil & water analysis
  • Better understand stage to stage production data
  • Understanding connectivity and wellbore flow patterns via WST & OST
  • Understand stage to stage stimulation effectives
  • Evaluate fracture geometry with RA / Logging
  • Understand where radioactive beads are placed in fractures
