Testing Tools

Hydrotestors has designed and manufactured tubing and casing pressure testing tools for over 35 years. As well Hydrotestors has designed and manufactured for sale the actual pressure testing truck, this same design with some modifications can be used in any skid mount or sea-can applications. Pressure Testing Trucks, Skid Mounted, or Sea-Can Unit can be custom ordered depending on the pressure requirements needed, standard units come with a 15,000 PSI or 70MPA pressure pump capabilities. (Pressure Testing Truck pictures are listed as 7A and 17A)

Tubing Testing Tools or two hose full body testing tools

(7” (177.8mm) Top Tool picture listed as same name)

Hydrotestors has designed and manufactured two-hose full body testing tools
Tubing sizes – 2 3/8” (60.3mm), 2 7/8” (73mm), 3 ½” (88.9mm), 4” (101.6mm), and 4 ½” (114.3mm)
Casing sizes – 4 ½” (114.3mm), 5” (127mm), 5 ½” (139.7mm), and 7” (177.8mm)

These style of testing tools test the tubular in the same way as to simulate the 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 fiberglass 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 and therefore results in the rapid detection of minor leaks.

This combined with computerized pressure recording using a pressure transducer ensures more accurate pressure readings and leak detection.

Hydrotestors tools having two pressure sources 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 severely rod cut, corroded, or tubing with appreciable scale build-up.

Utilizing these testing procedures could also be a cost effective program to help prolong the life of the tubing or casing.

The testing bar tool can also drift the tubular and connection after being made-up, as 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 therefore 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 most bottom hole equipment, packers, seal assemblies, anchors, nipples, injection mandrils, frac ports, right up to and including a wellhead, frachead, tubing hanger, or blow-out preventors (BOP’s).

This tool design has a working pressure rating of 15,000 PSI or 104 MPA, with a 3-1 safety factor built in to that rating.

Casing Testing Tools or two hose connection testing tools

Casing Sizes – 7” (177.8mm), 7 5/8” (193.7mm), 8 5/8” (219.1mm), 9 5/8” (244.5mm), 10 ¾” (273.1mm) and 11 ¾” (298.5mm)

This style of testing tool tests the casing in the same way as to stimulate the 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 casing tool uses two pressure sources; one to activate both sets of packer elements, and the other to supply the test port pressure.

This bar tool is designed to test one connection at a time, it is connected via a rope socket to the wireline on the testing unit throughout the complete testing process. The tool is lowered into the casing for each test and is removed between tests. The testing fluid inside the tool is retained throughout the testing operation. The length of a test is about two minutes from the time the tool is lowered into the casing, the test completed and the tool is pulled out.

Hydrotestors casing 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.
