CAM20-MT inline: 2-inch nominal multitrim choke with an inline body.
CAM30-MT: 3-inch nominal multitrim choke with an angled body.

Drilling Applications

CAM30-DC: 3-inch nominal multitrim drilling choke with an angled body.
CAM40-DC: 4-inch nominal multitrim drilling choke with an angled body.
CAM70-DC: 7-inch nominal multitrim drilling choke with an angled body.

Interchangeable Solutions
Trim interchangeability boosts operational efficiency by allowing a single choke to handle various scenarios, reducing maintenance needs and extending service life. This adaptability is vital for efficient well production and equipment longevity.

Trim Changeout Scenarios

Early to midlife: Controlled startup and severe sandy service using External FS trim.
Midlife to late life: Sand production and peak production using N&S trim.
Debris blockage risk and maximum flow: Scenarios using N&S trim.

Trim Types and Specifications
Available trim types include External FS, Needle-and-Seat (N&S), Gate and Seat (G&S), and Positive bean, each with specific orifice sizes and Cv values tailored to different operational needs.

Multiple Trims, One Choke Body
Multitrim drilling choke valves are versatile for a range of applications, including well control and testing. They offer multiple actuation options and interchangeable trims, enhancing operational flexibility and efficiency.

Advanced Drilling Techniques
For techniques like Managed Pressure Drilling (MPD), the external FS trim provides high control resolution and erosion resistance, crucial for maintaining stable wellbore pressure.

Actuation Options
Chokes can be easily converted between electric and manual operation, with electric actuation offering rapid adjustment and positional accuracy, unaffected by ambient temperature changes.

Specifications

Working pressure ratings up to API 15,000 psi.
Standard and alternative flange and end connection options.
API Specification 6A material classes and temperature classifications.

Spares and Maintenance
Available spares include trim kits, seal kits, and conversion kits for various configurations, facilitating efficient maintenance and operational flexibility.

Choke Selection and Management
Choke selection involves matching capacity and flow characteristics to field conditions, with options for positive or adjustable chokes. Effective choke management is crucial for operational efficiency, erosion resistance, and maximizing uptime through automation and maintenance.

Critical Control
The choke is a key controlling element in wellsite systems, essential for managing pressure and flow rate while enduring challenging conditions. Proper selection and operation of chokes prevent equipment failure and ensure optimal production levels.

Multitrim Production Choke Valves When specifying chokes for production-based applications, a fundamental challenge is accurately defining the flowing conditions and identifying potential complexities for the intended service. This information is vital in selecting the most appropriate choke type, trim style, and flow capacity for the choke such that it correctly aligns with the actual field conditions. Adapt the choke to the operating environment Although fully predicting the range of operating conditions is impossible, managing these unknowns and mitigating the potential risk requires versatility....
