Calcium Ammonium Nitrate - Oilfield Drilling Chemicals

Calcium Ammonium Nitrate

Oil and Gas drilling teams use Calcium Ammonium Nitrate for many different tasks.

When concrete is poured down recently drilled oil wellbores, Calcium Ammonium Nitrate can be added to the mixture to speed up the hardening process of the cement. It is can also be added as an agent to mortar and concrete during cold weather pours as it reduces the effects of the weather on the time that it takes these materials to harden.

When dealing with Invert oil-based mud emulsions, Calcium Ammonium Nitrate can be added to provide an extra source of calcium to the mud.

Calcium Ammonium Nitrate is used as a fertilizer for plants and crops. It is often used in the oil and gas industry for the “re-greening” of oil well locations.

It also provides extra calcium when clear-water drilling is taking place. Clear-water drilling is done in “hard rocks” in which density and fluid loss are not critical. water drilling.

Calcium Ammonium Nitrate can be added to any wastewater in order to reduce odor and smells being emitted from this pre-treated product.

China is one of the leading producers of Calcium Ammonium Nitrate in the world. The process to make Calcium Ammonium Nitrate is:

1. Calcium Oxide is crushed.

2. Calcium Carbonate is added.

3. Ammonium and water are added to the mixture.

4. This is then heated in tanks.

5. Nitrate is added to the mixture and it is dried.

6. Calcium Ammonium Nitrate beads are then formed.

7. The produce is filtered to the desired mesh size.

Preparation & Procedures

Calcium Ammonium Nitrate can be added to water in a clean drum or barrel. The resulting mixture can be added to the hopper. All involved in the preparation should be on alert for ammonia gas emissions which may be released when there is an excess hydroxide concentration.

Ammonia gas will irritate the nose, throat, and respiratory system and can cause eye injury. It is advisable to wear protective PPE, including a dust mask and eye protection while mixing powdered products.

Calcium Ammonium Nitrate should be stored securely away from combustible materials and reducing agents.
