Ven-Plug™ is a blend of water-soluble polymers and fibrous cellulose bridging agents. Ven-Plug™ is designed to be used as a highly viscous, temporary plugging agent in severe cases of lost circulation during drilling operations. It can also be used as a top hole drilling fluid and as a hole sweep.
Ven-Plex™ is an alkaline complexing agent designed to crosslink and further strengthen a Ven-Plug™ pill. Ven-Plex II is an alkaline complexing agent designed to crosslink and further strengthen a Ven-Plug pill. It is a powder that can be field formulated into a liquid.
Ven-Plug™ is recommended as a polymer-based lost circulation product for use in water-base mud systems. It is particularly effective in providing a highly viscous, pretreatment type of pill ahead of low viscosity cement slurries, LCM polymer pills, etc.
Although Ven-Plug™ is not designed to be a permanent pill, it will stay in place for a sufficient length of time to allow other types of permanent LCM pills, filter cake, or cement to be placed and set. Use of biocides will increase the life of the plug.
Ven-Plug™ can be used as a base fluid (rather than mud or gel) to build highly concentrated slurries with other types of LCM pills. Ven-Plug™ can be run ahead as a wiper ahead of cement jobs to provide a better distribution of cement throughout the hole.
