Polyflow

Downhole Application Questions

What are the advantages of PolyFlow's Thermoflex tubing versus Steel?
Thermoflex tubing provides superior corrosion resistance, reduced pressure drop to minimize back pressure against the formation and is light weight reduces installation costs.

Are there any special wellhead requirements for this tubing?
No. The tubing can be hung off with conventional tubing hangers or with a stuffing box.

How do I select the proper size tubing?
A PolyFlow representative will perform nodal analysis based on the data provided by a questionnaire provided by the customer and suggest the sizing options.

How does Thermoflex tubing react to H2S, CO2, Paraffin or Bitumen?
By properly specifying the correct polymers, Thermoflex tubing is inert or H2S and or CO2 and Paraffin and Bitumen will not stick to the polymers. However, the Paraffin's or Bitumen are not eliminated and will stick to the first metal. Thermoflex couplings must be coated with polymer for these applications.

What are the weaknesses versus steel?
Thermoflex tubing does have a lower collapse resistance than steel and the annulus of the tubing in the well has to be managed to minimize excessive back pressure.

Can Thermoflex tubing be fished?
Yes. By using a barbed spear, the tubing can be fished by coming along side the tubing, digging a barb into the outer cover, and "grabbing" the aramid fibers. The strength of the fibers will allow the tubing to be fished.

Gathering/Flow Questions

How does Thermoflex compete against conventional steel pipe?
Thermoflex requires much less installation equipment, personnel and time thus offering a lower cost solution on an as-installed cost basis. It also offers reduced maintenance costs through the elimination of chemicals (no corrosion) and reduced pressure requirements for compressors and pumps.

Can the product be used in both oil and gas?
Unlike polyethylene, this product is inert to oil, condensate, gas and CO2. Utilizing Fortron the product can withstand high concentrations of H2S.

Can the product be used at temperatures above 140°F, the standard maximum operating temperature of polyethylene?
The product comes in three maximum temperature ranges: 150°F, 180°F, and 250°F.

Who can install Thermoflex tubing?
The easy installation procedures allow local installation crews to install the product. Thermoflex representatives will train the local installers on proper coupling and installation techniques.

How do operators size the product accordingly with the benefits of reduced pressure drops versus steel?
Thermoflex representatives will model the lines based upon the input of the customer. Options will be generated and provided to the customer who will make the final decision.
