Casing centralization is one of the key elements to ensure the quality of a cementing job. It does so by preventing mud channeling and poor zonal isolation. While centralizers are used extensively, well problems continue to arise due to poor cementing jobs. The challenge that both operators and serv ...

The ultimate yet most difficult goal of cementing operations is to provide zonal isolation by displacing drilling mud with cement slurries. Incomplete mud removal creates a poor cement seal and non-productive time (NPT). To ensure critical zonal isolation with mud removal optimization, PVI has devel ...

PVI is currently developing PlugPRO, a cement plug placement model that calculates under-displacement volumes and optimizes fluid volumes to balance slurry and spacer levels after pull out of the hole (POOH). In addition, PlugPRO also models the displacement hydraulics of fluids. We look forward to ...

The first step to ensure an optimum completion is to remove leftover drilling fluid residue and casing debris. This requires that the drilling mud be changed out with solids-free completion fluids. Completion fluid displacement involves multiple fluids sequenced in circulation. Varying flow rates, f ...

Cement is fundamental in maintaining integrity throughout the life of the well. Even if the slurry has been properly placed, changes in downhole conditions can induce thermal and mechanical cycling stresses to harm the integrity of the cement sheath. PVI is developing CEMLife, a software package tha ...

A successful wellbore cleanup is one of the most critical steps to ensure a trouble-free completion. Cleanup operations reduce the risk of formation damage and enhance well productivity by efficiently and meticulously planning out the removal of leftover drilling fluid residue and casing debris. In ...
