Redress Kit for AP Style (Austin Powder) Compact Setting Tool

In the critical phase of wireline completions, the reliability of your Pressure Setting Assembly (WPSA) is the only thing standing between a successful plug-and-perf operation and a costly misrun. At Royal Way, we understand that a single O-ring failure can halt an entire frac fleet. That is why we engineer our Redress Kits not just to “fit,” but to outperform.

Technical Specifications

  • Standard Service (NBR): For routine operations up to 250°F.
  • High-Temp Service (FKM/Viton®): For deep, hot wells up to 400°F.
  • Extreme Service (Aflas®/HNBR): For Sour Gas (H2S) and chemically aggressive environments.

Sizes

  • Available for #10, #20, and Compact Setting Tools etc.

Product: Redress Kit for AP Style (Austin Powder) Compact Setting Tool

1. Executive Summary: The Compact Solution for Tight Spaces

In the fast-paced world of horizontal completions, lubricator height is often a luxury you don’t have. The AP Style (Austin Powder) Compact Setting Tool is the go-to solution for operators requiring a shorter, lighter, and more agile tool string without sacrificing setting force.

Our AP Style Compact Redress Kits are engineered to restore these specialized tools to factory performance. Designed to withstand the rigorous dynamics of Pump-Down Operations and the high-pressure spike of the power charge, these kits ensure your “Shorty” tool strokes fully and sets plugs securely, run after run. Whether you are using standard Austin Powder firing heads or compatible compact adapters, Royal Way provides the seal integrity you need to prevent misruns.

2. Compatibility & Identification

The “AP Style” tool is distinct from standard Baker #10 or #20 tools. It is characterized by its reduced overall length and specific internal seal geometry.

  • Tool Style: Austin Powder (AP) Style Compact / “Shorty” Type.

  • Primary Application: Plug-and-Perf operations where tool string length must be minimized.

  • Firing System: Optimized for tools utilizing Austin Powder Oil*Star detonators or similar compact firing heads  Fitment Guarantee: Our O-rings and backup rings are precision-molded to match the unique gland dimensions of AP-style compact cylinders and pistons.

⚠️ TECH TIP: Do not confuse this with the “Owen Shorty.” While similar in function, seal dimensions may vary. This kit is specifically curated for AP Style tool geometries.

3. Material Selection: Standard vs. Extreme Service

We offer two material grades to match your wellbore conditions and budget.

Option A: Standard Service (NBR)

  • Material: 90 Durometer Nitrile (Buna-N).

  • Temp Rating: -20°F to +250°F.

  • Best For: Standard pump-down stages, vertical wells, and operations where cost-efficiency is paramount. Our NBR is formulated to resist abrasion from proppant during the pump-down phase.

Option B: High-Temp / Sour Service (Viton®)

  • Material: Genuine Viton® (FKM).

  • Temp Rating: -15°F to +400°F.

  • Best For: Deep HPHT wells or wells with potential H2S exposure.

  • Why Upgrade? The firing chamber of a compact tool heats up rapidly due to its smaller mass. Viton® resists heat hardening, ensuring the tool can be easily disassembled and redressed after a hot run.

4. Kit Contents: A Complete Turnaround Solution

A Compact tool leaves zero room for error. Our kit includes every essential seal to isolate the wellbore and contain the setting pressure.

  1. Compact Firing Head Seals:

    • Precision O-rings to seal the interface between the AP-style firing head and the top sub.

    • Ensures electrical isolation for the detonator connections.

  2. Floating Piston Assembly:

    • Dynamic O-Rings: High-modulus seals to withstand setting pressures up to 15,000 PSI.

    • PTFE Backup Rings: Includes virgin Teflon backups to prevent extrusion during the power charge burn.

  3. Cylinder Connection Seals:

    • Static seals for the Upper and Lower cylinder housings.

  4. Bleed-Off & Port Plugs:

    • Replacement seals for the manual bleed-off ports (essential for safety).

5. Technical Focus: Pump-Down Durability

Compact tools are often pumped down lateral wells at speeds exceeding 400 ft/min.

  • The Challenge: High-velocity fluid bypass can “wash out” or roll standard O-rings out of their grooves before the tool even fires.

  • The Royal Way Advantage: We utilize High-Modulus (Stiff) compounds and precision-cut backup rings that lock the seals in place. This “anti-rollover” design ensures the tool arrives at setting depth with its hydraulic integrity 100% intact.

6. Operational Best Practices

  • Firing Head Check: The AP Style tool often uses a unique compact firing head. Always inspect the contact pin seals for damage, as a leak here causes a “Wet Fire” (Misrun).

  • Oil Fill: Compact tools hold less hydraulic oil than standard tools. Ensure all air bubbles are bled out to prevent a “spongy” set.

  • Backup Installation: Install the PTFE backup rings on the low-pressure side of the O-ring (away from the oil chamber pressure) to prevent extrusion.

7. Why Choose Royal Way?

  • Specialized Inventory: We are one of the few suppliers stocking specific AP Style kits, saving you from having to modify standard Baker kits to fit.

  • Batch Traceability: Full QA documentation with every bag.

  • Bulk Availability: Available in Master Packs (25+ units) for high-volume wireline trucks.
