Malvern Instruments’ Houston office hosts API working groups for drilling mud analysis

API working groups are currently assessing particle characterization techniques for oil drilling muds

The team at Malvern Instruments’ Houston (Texas, USA) office was delighted to host recent meetings on the 15th May 2013 of two American Petroleum Institute (API) working groups focussed on addressing the critical issue of how best to analyze drilling muds and the mineral components that they consist of. Specialists from Malvern – Dr Steve Ward Smith, Key Account Manager and Jon Layton, Gulf States Account Manager – sit on both groups which are working to enhance and standardize the methods used to characterize both aqueous and oil-based drilling fluids.

Drilling muds or fluids play a critical role in the oil industry. They maintain a safe and effective operation by: removing cuttings from the well; stabilizing and protecting the developing formation; and lubricating, cooling and supporting the drill bit. Closely matching a drilling mud to the geology of a well, and the requirements of the project, is crucial and relies on effective characterization of the product.

API WG4 (Working Group) is looking at the characterization techniques that can be applied to both oil- and water-based muds. This is a long term project, currently at a relatively early stage, that will examine how techniques such as automated imaging and laser diffraction can be usefully applied. It is likely to produce multiple standards over the next few years.

API WG3 has the more closely-defined objective of developing a new standard for the use of laser diffraction to analyze oil-based muds and is currently conducting round-robin tests to identify the impact of different methodologies on the results obtained. This work is expected to lead to a new API standard for the application of laser diffraction in drilling mud analysis some time next year.
