Providing while-drilling monitoring of mudgas chemistry for oil & gas exploration efforts. We are the leading provider of this technology. We have an experience base that includes hundreds of wells, including hundreds of shale wells. We have been involved with this technology for several years (since about 2001). We work on the drill site, usually in conjunction with preferred existing local mudlog service providers. While in some cases this technology has been considered for use in lieu of standard mudlogging, it is more usual that both services as complimentary efforts has seemed appropriate. Why Crown Geochemistry? This company is completely structured around delivering this data set. We don't do anything else. We have done (as an informal estimate) approximately 75% of the entire worldwide effort to date.
