III. Liner Systems - e.1.2. A1-L Liner Running Tool
The A1-L Liner Running Tool provides all of the benefits of its predecessor the A1 Liner Running Tool with some additional length between the packer setting collet and the cementing packoff seal. The additional length allows for the cementing packoff to remain in the tieback sleeve during positioning of the packer setting collet and setting of the packer. With the cementing packoff remaining in the tieback sleeve it is possible to perform a low pressure liner top integrity test.
Features/Benefits
  • Single mandrel provides for low cost & increased robustness
  • Clutched for rotation off ledges and setting mechanical hangers
  • Packer Setting Collet for reliable packer setting
  • Large ID for increased surge reduction
  • Distance between packer setting collet & cementing packoff allows for testing
