Complete Range & Capabilities
Our Thermal Packers
The SpectraMax Set Thermal Packer is a single-string, double-grip retrievable packer engineered for extreme temperature wells. Setting mechanisms include mechanical (J-slot) for standard installations and hydraulic actuation for higher-rated configurations.
Elastomer selection determines the operational ceiling for each model. HNBR compounds serve applications to 302°F (150°C). FKM (Viton-class) remains stable at 400°F (200°C) indefinitely, while FFKM (Kalrez-class) extends the envelope to 620°F (325°C) for the most extreme geothermal environments.
| Model | Type | Temp Rating |
|---|---|---|
| SpectraMax Set | Retrievable, double-grip | 350–450°F (177–232°C) |
| Max-Set Thermal | Retrievable | 350–400°F (177–204°C) |
Ratings, Materials & Performance Data
Thermal Packer Specifications
V0 is the highest design verification grade under API 11D1 (Spec 11D1, 3rd Edition) — testing uses gas (air or nitrogen) as the test medium rather than liquid, imposing the most stringent seal verification conditions. Design verification grades range from V0 (zero gas leakage) through V6 (lowest).
FKM compounds maintain seal integrity at 400°F (200°C) indefinitely with excellent resistance to hydrocarbons, ozone, and aging. FFKM compounds extend performance to 620°F (325°C) with near-universal chemical compatibility. All SpectraMax models above 350°F carry API 11D1 Grade V0 qualification.
HPHT is defined as 15,000–20,000 PSI and 350–450°F per SPE/industry standards. The SpectraMax series addresses the thermal dimension with metallic anti-extrusion backup rings that prevent elastomer deformation under differential pressure at elevated temperature.

ISO 9001 Foundation
General quality management certification underpins all manufacturing processes. In-house test cell at Vadodara eliminates third-party testing dependency.
Material traceability runs from raw elastomer stock through finished assembly. Each packer carries a unique serial number linking to its full manufacturing and test record. Every shipment includes MTRs, dimensional inspection reports, and test certificates.
SAGD, Geothermal & Steam Injection
Thermal Packer Applications
SAGD Operations
Steam-Assisted Gravity Drainage injects steam at 400–500°F through horizontal well pairs. Thermal packers provide zonal isolation between injection and production intervals, enduring continuous thermal cycling. The SpectraMax Set is rated for the full SAGD temperature envelope with V0 gas-tight assurance.
Geothermal Wells
Commonly exceed 400°F (204°C) with corrosive fluid environments requiring 20–30 year service life. Geothermal demand is trending upward sharply — +40% year-over-year. Proper elastomer selection under HPHT conditions combined with corrosion-resistant metallurgy determines long-term reliability.
Cyclic Steam Stimulation & Steam Flood
CSS imposes repeated heating and cooling cycles that stress sealing elements through compression set degradation. Steam flood and continuous injection demand sustained high-temperature resistance. The SpectraMax lineup addresses both continuous and cyclic thermal loading patterns.
Operators evaluating thermal packers should assess elastomer compound selection (HNBR, FKM, or FFKM), V0 seal qualification under the target temperature, and the manufacturer's thermal cycling test protocol. Maximus OIGA provides application-specific elastomer recommendations based on well temperature, pressure, and fluid composition.
In-House Facility
Manufacturing, Testing & Quality Control
Maximus OIGA operates a dedicated manufacturing facility in Vadodara, Gujarat, India. The facility houses purpose-built machining centers, elastomer processing equipment, and a test cell designed for packer verification under rated temperature and pressure conditions.
The SpectraMax thermal packer line represents 18 months of focused R&D, from elastomer compound development through full-scale API 11D1 qualification testing. In-house testing capability eliminates dependency on third-party labs — every packer is pressure-tested to failure protocol before shipment.
Custom engineering is available for specific well conditions including non-standard casing sizes, corrosive fluid environments, and combined high-temperature/high-pressure requirements beyond the standard SpectraMax catalog range.

Common Questions
Frequently Asked Questions About Thermal Packers
A thermal packer is a well isolation tool engineered for sustained operation above 350°F (177°C). Standard packers use general-purpose elastomers such as NBR, rated between 250–300°F, that degrade under sustained thermal load. Thermal packers use specialized compounds — HNBR, FKM, and FFKM — paired with metallic anti-extrusion backup rings to maintain seal integrity through extreme temperature and thermal cycling. The SpectraMax series is rated from 350°F to 450°F with API 11D1 Grade V0 gas-tight certification.
SpectraMax thermal packers operate continuously at 350°F (177°C) to 450°F (232°C), depending on model and elastomer configuration. All models above 350°F are qualified to API 11D1 Grade V0 — zero gas leakage at maximum rated temperature and pressure. Elastomer options include HNBR (to 302°F / 150°C), FKM (to 400°F / 200°C indefinitely), and FFKM (to 620°F / 325°C) for extreme geothermal applications.
Yes. Geothermal wells commonly exceed 400°F (204°C) and expose completion equipment to corrosive fluids over service lives of 20–30 years. Thermal packers provide zonal isolation critical for geothermal stimulation and production. The SpectraMax thermal packer is designed for SAGD/geothermal crossover applications, with FFKM elastomer options extending capability into high-temperature geothermal service.
V0 is the highest design verification grade under API 11D1 / ISO 14310, requiring zero gas leakage during testing at maximum rated temperature and pressure. The test medium is gas (air or nitrogen), not liquid — a significantly more stringent requirement than lower grades. All SpectraMax thermal packer models above 350°F are V0 qualified, with test certificates documenting actual seal performance.
Thermal cycling — repeated heating and cooling in SAGD, CSS, and geothermal wells — causes elastomer compression set degradation, dimensional changes, and progressive seal deterioration. The SpectraMax thermal packer uses metallic anti-extrusion backup rings and specialized elastomer compounds to maintain seal integrity through repeated thermal cycles. Proper material selection based on the specific cycling profile of the well is critical to long-term performance.
