Lost Circulation - Additive Considerations

Additive Considerations

Several factors are considered in what additives are used:

• Hole size currently being drilled.
• Drilling fluid in use. The additives must be compatible.
• Depth of the well in regards to geological stability.
• Depth of well in relation to the desired production zones. Plugging a production zone is not a desired outcome.
• Drill bit nozzles sizes. If the additive(s) will not go through the drill bit, they cannot be used.
• Other drill string mechanical equipment such as a mud motor or MWD tools. If the additive(s) will not go through the drill string, they cannot be used.
