Hydrotestors has designed and manufactured tubing and casing pressure testing tools for over 40 years. We can build either a single hose or double hose tools for testing the complete tubular body including the connections, or smaller length connection only tools. We have also developed speciality tools for completing Bottom Hole Assembly tests, Anchors, Frac Sleeves, Frac Ports, Gas Lift Mandrels, Injection Mandrels, Crossovers, etc.
TWO HOSE TOOLS OR SINGLE HOSE TOOLS FOR THE COMPLETE TUBULAR BODY
- Tubing sizes are 2 3/8” (60.3 mm), 2 7/8” (73 mm), 3 ½” (88.9 mm), 4” (101.6 mm), and 4 ½” (114.3 mm)
- Casing sizes are 4 ½” (114.3 mm), 5” (127 mm), 5 ½” (139.7 mm), and 7” (177.8 mm)
TWO HOSE TOOLS FOR CASING CONNECTIONS
- Casing Sizes – 7” (177.8 mm), 7 5/8” (193.7 mm), 8 5/8” (219.1 mm), 9 5/8” (244.5 mm), 10 ¾” (273.1 mm), and 11 ¾” (298.5 mm)
These style of testing tools test the tubular in the same way as to simulate a similar direction of pressure applied during fracing, injection, or production. The two-hose design utilizes a bar tool with two upper and two lower expandable packer elements. This bar tool uses two pressure sources: one to activate both sets of packer elements, and the other to supply the test port pressure.
Hydrotestors bar tools have been designed with a range of outside diameters that minimize the volume of fluid needed in the test area while still maintaining a safe margin for tool clearance in the tubular. Bar tools can also be coated in a durable urethane to help minimize any damage while testing fibreglass or any internally coated tubing.
These features are very beneficial as it minimizes pumping time to achieve the desired pressure, and also allows for very high resolution, resulting in the rapid detection of minor leaks.
Benefits of two-hose testing tools
Having two pressure hoses is an important feature as it allows truck operators to establish a seal with the packers prior to applying the pressure to the tubular.
This advantage becomes very apparent when pressure testing that has significant scale build-up or is severely rod cut or corroded. Utilizing these testing procedures is a cost-effective solution to prolonging the life of tubing and casing.
The testing bar tool can also drift the tubular and connection after being made-up. The testing tool sits below the next connection and has to pass through the next joint of pipe and the connection before the next pressure test is completed, ensuring that the tubular has not been crimped and the connection is not pinned in from over torque.
This system can, in some cases, also test bottom hole equipment like packers, seal assemblies, anchors, nipples, injection mandrils, frac ports, and even including wellheads, frac heads, tubing hangers, or blow-out preventers (BOP’s).
These tools are designed for a working pressure rating of 15,000 PSI or 104 MPA, with a 3-1 safety factor built into that rating.
