MUDPRO+, an advanced version of MUDPRO, records all actions mud engineers perform on mud, including additions, losses, returns and transitions. MUDPRO+ also keeps track of mud volumes on a daily basis. This software calculates the concentration of all additives during the drilling cycle and comes wi ...

Casing wear during drilling and workover is an on-going concern. It will continue to have an impact on both well path and operation designs because it can cause catastrophic incidents such as oil spills, blowouts or even the loss of a well. PVI has conducted studies on casing wear from both an exper ...

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 ...

A successful cement job is one of the most important factors for of any well. There are many challenges involving increased reservoir depth, downhole temperature and pressure. Achieving wellbore integrity is more complicated than ever before. To overcome these challenges, PVI developed CEMPRO, an in ...

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 ...

Cementing operation success or failure can potentially make or break the financial viability of a well or project. It is vital to correctly perform calculations and prevent mistakes during the design stage of a cementing job. As new technology evolves, the calculations of various parameters for ceme ...

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 ...
