Title (EN) FAST MUD GAS LOGGING USING TANDEM MASS SPECTROSCOPY
(FR) DIAGRAPHIE DE GAZ DE BOUES RAPIDE UTILISANT LA SPECTROSCOPIE DE MASSE EN TANDEM
Abstract: front page image
(EN)Systems and methods for high speed mud gas logging are described. A general workflow of mud gas logging uses tandem mass spectroscopy. The workflow involves first separating the volatile components of the hydrocarbons (typically C8 and below) from the drilling fluid using a fluid extractor (or degaser). Extracted gases are then diluted in air and transported to an analyzer, which measures the concentration of each of those gases in air. A tandem mass spectroscopy-based analyser is used that is able to quantify each of those hydrocarbon components, including resolving isomeric species, while tolerating the presence of the non-hydrocarbons. According to some embodiments, triple quadrapole mass spectroscopy is used.
(FR)L'invention concerne des systèmes et des procédés pour effectuer des diagraphies de gaz de boues à grande vitesse. Le flux de travail général de la diagraphie de gaz de boues fait appel à la spectroscopie de masse en tandem. Le flux de travail consiste tout d'abord à séparer les composants volatils des hydrocarbures (typiquement C8 et en dessous) du fluide de forage en utilisant un extracteur de fluide (ou un dégazeur). Les gaz extraits sont ensuite dilués dans l'air et transportés vers un analyseur qui mesure la concentration de chacun de ces gaz dans l'air. Un analyseur à spectroscopie de masse en tandem est utilisé et permet de quantifier chacun de ces composants hydrocarbures, y compris de résoudre les espèces isomères tout en tolérant la présence de non-hydrocarbures. Dans certains modes de réalisation, on utilise la spectroscopie de masse triple quadripôle.
