Role Of Gelling Agents In Drilling, Oil And Gas Industry

Gelling agents contain chemicals that have the properties to bind and react with oil

, forming a gelled substance. These can be used to provide sufficient energy to mix the chemicals with the oil in rough seas.

Barite

A gelling agent such as barite is added to increase the overall density of drilling fluids as it does not react with other fluids or hamper their functioning. This chemically alert and insoluble agent is used to increase the density of any mud system and maintain rheological properties at the same time. It is among widely used drilling weight materials due to its high specific gravity.

CARB Coarse/Medium/Fine Calcium Carbonate

CARB is widely used in drilling as a bridging and weighing agent for controlling fluid loss and density. This effective bridging agent is used to increase mud density and is grinded in three sizes: Coarse, Medium and Fine. CARB C and CARB M are used for bridging and seepage control and CARB F is used as a weighing agent. You can select the most suitable size that can be used to suit your exact application.

Guar Gum

Guar Gum, among widely used gelling agents, is used to increase the production rate of oil and gas. It is highly concentrated regarding its gel-like properties and increases the oil productivity. It disperses readily in cold or hot water to form a pseudoplastic solution. It is used as a drilling mud and fracturing gel in oil and gas industry and as froth flotation and flocculating agent in mining. Guar Gum is wet end strength addictive and thus is also used in paper industry.

Bentonite

This Viscosifier and Filtration control agent is used for drilling muds for the purpose of controlling borehole stability. It helps to improve hole cleaning capacities of drilling fluids. Also, it can be added directly to fresh water or fresh water based drilling fluids.

Hematite

Hematite is one of the most effective gelling agents used to increase the density of drilling fluids and controls formation pressure. As compared to barite, it has a lower attrition rate and specific gravity which offers excellent benefits.
