Abstract:
1. A method of inserting a downhole assembly into a live wellbore, comprising: assembling a pressure control assembly (PCA) onto a production tree of the live wellbore; inserting a first deployment section of the downhole assembly into a lubricator; landing the lubricator onto the PCA; connecting the lubricator to the PCA; lowering the first deployment section into the PCA; engaging a clamp of the PCA with the first deployment section; after engaging the clamp, closing an isolation valve of the PCA, thereby isolating an upper portion of the PCA from a lower portion of the PCA; after isolating the PCA, removing the lubricator from the PGA; connecting a second deployment section to the first deployment section; connecting a third deployment section to the second deployment section; inserting a fourth deployment section of the downhole assembly into the lubricator; landing the lubricator onto the PCA; connecting the lubricator to the PCA; opening the isolation valve of the PCA; lowering the fourth deployment section into the PCA to a position adjacent a top of the third deployment section; and while the lubricator is connected to the PCA:
