Product Description
Cesium Formate is chemically represented by the formula CsCOOH. Cesium Formate is prismatic crystals organic salt and readily soluble in water. Cesium Formate is available as stock, clear fluid which can be used in drilling, completion and perforating operations that require a density to 19.4ppg(2.32SG) and a base liquid for drill-in fluids. It owns all the advantages of Potassium Formate and Sodium Formate brines, especially in many HPHT applications. It has been utilized successfully in a lot of HPHT wells around the world. Cesium Formate passed
rigorous field test with a density up to 19.2ppg(2.30SG) and temperatures stable up to 419°F as long as 18 months application. It can be used in highly deviated and long horizontal wells, as well as low permeable oil/gas and condensate reservoirs.
Applications/Functions
• Used as a base liquid for drill-in fluids in HPHT wells
• Used as completion brines in perforating operations with minimal reservoir damage to increase production recovery rate
Advantages
• Owns all the advantages of Potassium Formate and Sodium Formate brines, especially in many HPHT applications with temperature stable up to 450°F
• No solids weighting agents, low gel strength, low instantaneous peak pressure when break gel, thus low-pressure surge with enhanced hole stability
• No sag issue at all, low ECD, minimized screen pipe plugging risks
• Low activity of aqueous solution provides enhanced hole stability
• High core permeability with minimal reservoir damage; Environmentally friendly product
Typical Properties
• Appearance: Clear liquid or white crystal
• Specific gravity of solid: 2.23
• Solution pH: 5.5-6.5
Recommended Treatment
• Drilling conditions and mud system requirements dictate concentration levels
Package
• 1000L IBC TOTES
