Chloride Salts - Week 2 Flashcards
Calcium Chloride - Composition
Calcium Chloride (CaCl2)
Calcium Chloride - Varieties
Powdered, granulated, pelletized
Calcium Chloride - Primary Function
Increases density of water for workover/completion purposes
Calcium Chloride - Secondary Function
Controls water activity in invert emulsion muds
Calcium Chloride - Limitations
- maximum density of 1.4 SG (11.6 ppg)
- Calcium Chloride is corrosive to metal and skin. Use appropriate PPE when mixing
Calcium Chloride - Features and Benefits
Provides density and an inhibition environment for drilling and completion operations. Is being used in drilling operations
Calcium Chloride - Treatment
As needed for saturation
Potassium Chloride - Composition
KCl
Potassium Chloride - Primary Function
Shale Control
Potassium Chloride - Secondary Function
Increases density of water for workover/ completion purposes
Potassium Chloride - Features and Benefits
Provides density and an inhibition environment for drilling and completion operations
Potassium Chloride - Treatment
As needed up to saturation
Salt - Composition
NaCl
Salt - Primary Function
Shale Control
Salt - Secondary Function
- Increases density of water for workover/ completion purposes
Additional Functions:
1. Suppresses gas hydrate formation
2. Retards the dissolution of massive shale sections
3. Can be used to control the water activity in invert emulsion muds
4. Coarse ground salt is used as a bridging agent for lost circulation or drill-in fluids
