Drilling muds are oil- or water-based suspensions that are used in drilling oil and natural gas wells. The muds have several critical roles in the extraction process. Some of the functions include:
Drilling fluids are tuned to have unique properties that suit their applications. For example, the drilling mud used in deep shelf drilling will have different properties from the mud used in drilling shallow wells. The desired properties are attained by adding different chemicals to the drilling mud. Typically, drilling muds contain the following additives:
The particle size is one of the most significant properties when evaluating the performance of the drilling mud. The particle size of the drilling fluid determines the equipment performance in a specific well. Below are some of the factors that make the particle size an important property of the drilling mud.
A thorough particle size analysis is particularly valuable in minimizing damage to the surrounding rock formation. Fine particles from the rock cuttings and polymeric material from the drilling fluids can damage the production zone. For the filter cake to be an effective barrier against the destructive agents, the particle size and particle distribution of the filter cake must be taken into consideration.
Aerion can assist with particle size analysis to evaluate the particle characteristics of different drilling fluids. Our highly-trained staff analyze the properties of the production zone to determine the optimum drilling fluid particle size for extraction efficiency and for protection of the production zone.
