Summary Running In Hole Retrievable Test-Treat-Squeeze Packer (RTTS Packer)

SUMMARY Well 06 West Sumatra Field

RTTS packer is used for testing, treating, and squeeze cementing operations or Fracturing. In most cases, the tool runs with a circulating valve assembly. The packer body includes a J-slot mechanism, mechanical slips, packer elements, and hydraulic slips. Large, heavy-duty slips in the hydraulic hold down mechanism help prevent the tool from being pumped up the hole. Drag springs operate the J-slot mechanism on ≤ 3 1/2-in. (88.9-mm) packer bodies, while larger packer sizes≥ 4-in. (101.6 mm) use drag blocks. Automatic J-slot sleeves are standard equipment on all packer bodies.

   Features and Benefits using RTTS Packer :

1. The full-opening design of the packer mandrel bore allows large volumes of fluid to pump through the tool. Tubing-type guns and other wireline tools can be run through the packer.
2. The packer can be set and relocated as many times as necessary with simple tubing manipulation
3. Tungsten carbide slips provide greater holding ability and improved wear resistance in high- strength casing. Pressure through the tubing activates the slips in the hydraulic holddown mechanism.

I wanna Share my story about Set RTTS packer mybe looks easy, but actually very high risk and danger. Many people who judge set RTTS packer thing is easily, just turn right / turn left. They see only a small part of a long process and procedure. That’s long process they did not see. Before do the job, the engineer must know the history of the well and discuss with Company man before doing the job. Knowing the history of the well is very useful to anticipate problems that will exist. And knowing the details of the work done is also very important, how to do a good job but we don’t know what will be do.

After knowing the proposal well, then the next step is about the RTTS packer. When the packer arrives at the location, and then engineer should be checking the packer that came. Checks should be done thoroughly, as every part of the packer should work properly. After doing a thorough checking then the engineer must determine which packer is more feasible to use because there are usually two packers available. After determining the packer to be used, then the packer must be ensured again that the selected packer in the state really worth using. The engineer must re-tighten each part of the packer. After tightening each part, the engineer should check the lock system on the packer, lower slip, rubber, piston slip, pad friction, and Not forget also to tighten the lnkey contained in the packer. After double check, the engineer must ensure the size of the tubing or drill pipe will running. If not in accordance with the size of the packer to be used, the packer should be added croos over. When the engineer was done to ensure, then the time RIH RTTS packer. When running the packer into the well, it takes carefulness and patience Running in Hole, When RIH must be considered the current speed RIH looking monitor and discuss with floor man and driller Do not  to fast, because if it is to fast it will happen prematurely set. Also in the packer set required patience and carefull analysis.

This the procedure to Running RTTS Packer :

1. To tight the centralizer and stab in head with rope or others 
2. Make sure the shear pin screw in place with CR
3. Clean up the tools near the wellhaed,and cover it.
4. Scrape and wiper trip before running MMR  
5. Smoothly running and operationProhibit  suddenly brake and release                               
6. Locked the totary table and tight the backup tong while the DP connection
7. prohibit the DP right turn
8. Circulation until hole clean before running CR
9. Good Comunication with Coman and Driller when doing POOH and after that don't forget checking the tools.
