Introduction

Weighting Agent solution is used during work-over and completion operations to provide a clear brine fluid at a density of up to 14.2 lb/gal. It provides inhibition, preventing hydration and migration of swelling clays, and can be used for packing fluids or to adjust the density of another brine system.

We provide innovative, highly effective alternatives to traditional calcium bromide high-density completion fluids with the following modes of action

Weighting Agent is a new innovative, high-density solids-free, completion fluid. Weighting Agent Bromine-free completion fluid is the clear solution to the industry’s quest for an environmentally friendly, cost-effective alternative to traditional calcium bromide high-density completion fluids. Weighting Agent is a high-density (14.2 lb/gal, 1.7gr/ml), solids-free fluid that can provide an alternative to calcium bromide brines. Weighting Agent was designed for use in well-completion and work-over operations.

Application Information

density up to 14.2 lb/gal. It provides inhibition, preventing hydration and migration of swelling clays, and can be used for packer fluids or to adjust the density of another brine system.

Weighting Agent is formulated, predominantly using brines and a complex, proprietary blend of additives, which achieves high-density completion fluids.

Features

• Can be formulated to a density of up to 1.7 g/ml (efforts are underway to extend the limits).
• Exhibits significantly lower crystallization temperatures than equivalent-density calcium bromide brines
• Stable at elevated temperatures and during storage. Clear-brine Work-Over and Completion Fluids
• Can be mixed with standard mixing equipment.
• Compatible with downhole elastomers and metallurgies and poses a low corrosion risk. Exhibits compatibility similar to that of calcium bromide with other working and reservoir fluids.
• Formulated from renewable products, ensuring continuity of supply.
• Can be formulated as a low-solids reservoir drill-in fluid.
• Performs at low temperatures and high pressures without crystallization. Benefits
• Bromine-free, hence does not have bromine corrosion
• Can be reclaimed for reuse, using standard technology.
• Neutral in pH, and compounds thereby posing low health and safety risks to rig site and plant Personnel.
• Significantly lower unit cost than alternative fluid chemistries.
• Requires no special mixing, handling, or storage equipment at the rig site.
• Environmentally friendly.
• Formulated from renewable products, ensuring availability of supply.
• Poses low health and safety risks to rig site and plant personnel

Packaging and Storage

Weighting Agent stored in corrosion-resistant containers and kept closed and firmly sealed. It is a concentrated hygroscopic salt solution that will absorb water from the air, reducing density if not properly stored.

This product should not be exposed to direct sunlight during storage Weighting Agent is packaged in 340 kg net wt. (750 lb. net wt.) polyethylene or steel drum.

Shelf Life

Weighting Agent has a shelf life of at least one year from the date of manufacture when stored in the original sealed containers in a cool and dry place.

Safety and Handling

Weighting Agent poses similar HSE risks to calcium bromide brine. Avoid skin and eye contact, inhalation, or ingestion. For skin contact, wash with soap and large quantities of water. For eye contact, flush with large quantities of water for a minimum of 15 minutes; seek medical attention. Use a property-designed respirator if adequate ventilation is not available.
