Figure 1

InTouch Ticket 3053798 Chemical Injection using Reda power cable with capillary tube

Figure 1.Figure 1 shows the typical configuration (without down-hole barrier). This system included a packer, which is not common with continuous chemical injection. A special feedtrhu connector with a 3/8" capillary tube by-pass--in addition to the three electric conductors--was used for this installation.

Are you using Sub Surface Safety Valves (SSSV)in the production tubing string? If the answer is no, there is no need to install a down-hole barrier in capillary tube.

The check valve (5)--installed at surface--is the physical barrier to prevent back-flow. In addition to this check valve, you can install a valve with electronic actuator in the injection line. A company such as Milton Roy-Flow Control Division http://www.miltonroy.com/ can help with the application of these valves.

In regards to your question on the termination of the capillary tubing and the physical attachment of the tubing to the equipment below the FCE splice, it can be very simple for vertical wells or more elaborated for deviated or high profile wells. It is more a plumbing job that has to be done in the Geo Market. We have not developed engineering procedures nor drawings.

Figure 2-a

Figure 2-b

Figure 2-a shows the simplest arrangement, using the same type of cable bands to attach the tubing to the motor, surveyor and pup-joint if used. The tubing is external to the pup-joint and is terminated in U shape. Lasalle protectors and encapsulated line can be used for additional protection of external tubing. (see figure 3). The A.O.P.C. LIUHUA COMPLETION DIAGRAM with Lasalle Downhole Chemical Injection Line in Figure 3 shows a more elaborated system.

In the internal tubing approach shown in Figure 2-b, the capillary tube is protected, and is terminated bending in a U shape, or Swagelok fittings (elbows, tees, etc) You can find information on fittings and tools required at http://www.swagelok.com/index.asp

The use of the Swagelok tube bender permits easy forming of the tubing in the field, or the pup-joint assembly could be pre-assembled and tested and then connected in the filed during installation

Figure 2-c

Figure 2-c includes a discharge manifold.

The use of the Swagelok tube bender permits easy forming of the tubing in the field, or the pup-joint assembly could be pre-assembled and tested and then connected in the filed during installation. Option 2-c would be preferable handled this way.

Figure 3

Concerning to your question on availability of check valves for this type of installation, you are right, there are check valves available, for example Swagelock CH8 Series check valves. I downloaded the catalog below for your reference.

You can find additional information at: http://www.swagelok.com/Two issues to consider when installing a check valve at the bottom of the capillary tube , as opposed to the check valve at surface as illustrated in Figure 1, are first, the possibility of obstruction of the check valve at downhole conditions, and second the pressure rating of the capillary tube.

Obstruction of the check valve.

The concern is that debris, scale, wax, or other substance could interfere the operation of the check valve.

Working Pressure rating of the capillary tube.

The most common capillary tube we use is SS 316L, 3/8in O.D., 0.049in wall. The internal working pressure for this tube is between 4,800 to 4,900 psi. This theortical internal working pressure is de-rated when operating at high temperatures. One manufacturer (GIBSON TUBE, http://www.gibsontube.com ) provides the follwing correction factors for SS 316L: 0.93, 0.84, 0.75 for temperatures of 100 F, 300F, and 500 F respectively.

If the capillary tube is run with its end open, the fluid enters the tubing and therefore, the internal pressure is the same as the external pressure.

If there is a check valve at the lower end of the capillary tube, the fluid cannot enter the tube, therefore the external pressure will be higher, unless the tubing is continually filled with liquid while it is run. This is not usually a problem, but something to consider in deeper applications. The external pressure will depend on the fluid level and the fluids specific weight.

This configuration or a chemical injection mandrel should be considered only if a downhole barrier, such as Sub Surface Safety Valves (SSSV) are installed in the production tubing string.Proprietary Information
