A testing apparatus for onsite creation of cured sample liners necessary for confirming proper rehabilitation of pipelines includes a testing box having a base with a plurality of upstanding side walls defining an open upper end of the testing box. The testing box also includes an electrical power control assembly and an ultraviolet light assembly. A liner support manifold is shaped and dimensioned for supporting a sample liner and for attachment to the open upper end of the testing box for exposing the sample liner to pressure and ultraviolet light. In practice, and with the sample liner secured to the liner support manifold and the liner support manifold secured to the testing box, the sample liner is exposed to pressure and UV light in a highly controlled manner allowing for replication of actual in-line curing processing.

A moisture detecting bleeder material includes a fiberglass material and a moisture absorption indicator material. The moisture absorption indicator material is a component of the fiberglass material and undergoes a color change from a first color to a second color when exposed to moisture. The color change may be thermally irreversible below a threshold temperature (e.g., below a temperature of 450 F.).

A flexible package including a package body including a first side-surface film and a second side-surface film sealed in a peripheral portion. The package body has sealed portions formed in side edge portions such that a non-sealed portion is formed in at least one of the sealed portions. The non-sealed portion has a gas injection portion containing a gas which has a specific heat at constant volume of 0.67 kJ/kg.Math.deg or higher at 0 C. and 1 atm. The gas injection portion has a diameter of from 3 to 50 mm and is formed such that a repelling force is from 4 to 30 N at 23 C. and 1 atm when an entire gas injection portion is nipped from both sides of the first and second side-surface films and squeezed until a nipped gas injection portion has a width equal to a half of the diameter of the gas injection portion.

A system and method for transmitting data from within a wellbore to a surface location includes downhole tool that is nm into the wellbore. The downhole tool includes a sensor, a processor, and a transmitter. A pressure response in the wellbore is measured with the sensor. A function that approximates the pressure response is determined. The function is transmitted to the surface location with the transmitter.

A measuring device for measuring a concentration of a gas component in a gas includes a flow generating device, a first conduit, a second conduit, and an electrochemical detector configured for sensing the gas component concentration in the gas. The first and second conduits are arranged in parallel, and the flow generating device is connected with an inlet of the first conduit and an inlet of the second conduit. The flow generating device is arranged for generating a gas flow in each of the conduits. The measuring device is arranged to alternately couple either an outlet of the first conduit or an outlet of the second conduit to an inlet of the detector, wherein the first conduit is provided with a reactant for absorbing or stripping the gas component.
