As computing power and expertise grew, Schlumberger was able to launch several revolutionary products.
- The FMI fullbore formation microimager now enabled seemingly photographic images of the borehole.
- The Platform Express integrated wireline logging tool introduced a much faster and more cost-effective way of achieving the same results as the triple-combo logging system, speeding up rig-up, logging, calibration, and processing.
- The launch of the third-generation nuclear magnetic resonance (NMR) tool in 1995 refined reservoir evaluation still further, facilitating the identification of thin, permeable, or water-free productive zones.
- Sonic imaging also developed to the extent that Schlumberger completed its first commercial job using the technology in 1996.
- At the start of the decade, geosteering was used for the first time in horizontal wells, using logging data acquired while drilling a borehole to adjust the path of the drill to keep it within the producible hydrocarbon deposit.
A spate of acquisitions helped the company grow and diversify its activities. PRAKLA-SEISMOS, GeoQuest Systems, Oilphase, and Camco International were some of the companies that became part of Schlumberger. Strategic collaborations were also forged, such as the Omnes, a joint venture between Schlumberger Cable & Wireless for global communications and information technology services, and the M-I L.L.C drilling fluids company in a venture with Smith International.
In 1995, Schlumberger launched Integrated Project Management (IPM), which today continues to provide the expertise and processes required to improve performance and increase efficiency by integrating all the oilfield services and technologies needed by a project.
Once again, Schlumberger was able to support pioneering science, by providing logging services to the German Continental Deep Drilling Program, or KTB, examining various geological processes. This illustration of the continuing close ties between the company and the wider scientific community would have pleased Henri Doll, who died in Paris on July 25, 1991, shortly before his 90th birthday. He is buried, as he wished, next to his mentor, Conrad Schlumberger, in a small cemetery at the Schlumberger family estate in Normandy, France.
