Mud gas analysis


 

During the drilling process, mud (also known as drilling fluid) is pumped down the well to the drill face to keep the drill bit cool, facilitate the movement of cuttings to the surface, and prevent clogging and friction. Polymers, clays and other medium are other added to the mud to improve drilling performance.

Mud logging is the process of collecting data associated with the mud which has returned to the surface from the drill face. By observing important characteristics in the mud such as lithography, consistency, temperature and natural gas composition, a ‘mud logger’ can identify possible indications of hydrocarbons. SIFT-MS is the ideal on-site and on-line analytical technique for hydrocarbon detection in mud-logging, due to its high speed, high selectivity and minimal sample handling requirements.

Syft Technologies’ mud logging solution is the ultimate instrument for hydrocarbon analysis of mud gas


Syft’s Mud-logger solution provides fast, reliable, and economic analysis of drilling mud at the well site.

High-penetration-rate drilling technologies present a challenge to current mud-gas analysis techniques: they are either too slow (gas chromatography), or do not quantify a complete range of compounds (photometric and electrochemical techniques). For example, gas chromatography (GC) analyses are often limited to 1 – 5 minutes per analysis cycle, and compounds containing less than six carbon atoms. Faster photometric and electrochemical techniques detect only a limited range of compound types.

Our Mass Spectrometry (SIFT-MS) overcomes these limitations, identifying and quantifying volatile organic compounds (VOCs) directly from mud-tank headspace gas in real time to the mid-part-per-billion (ppb) concentration range. Hence SIFT-MS makes real-time hydrocarbon analysis viable in high penetration rate drilling operations.

Only the high-speed, direct mass spectrometric analysis provided by Syft Technologies’ Mud-logger solution keeps pace, providing reliable and economic analysis at well sites around the globe, such as Texas, the North Sea, and China.
