Advanced Geosteering Methods for Optimal Exploitation of Hydrocarbon Reserves


Speaker: SPE Distinguished Lecturer
Roland E. Chemali

Location: Congress Center of RF CCI. Start at 7 p.m.

Abstract:

Optimal field development entails placing the wells in prescribed locations within the reservoir. An error of a few meters in height above the oil-water contact or with respect to the roof may result in leaving behind a significant portion of the producible reserves in later years. Early production rates also depend on well placement and reservoir contact. Driven by these key requirements, new technologies continue to emerge to help geologists, drillers, and reservoir engineers make well informed geosteering decisions.

Best geosteering results are attained by integrating multiple real time measurements and images, and interpreting them jointly. Shallow images of the borehole help recognize when a well path has left the reservoir and determine the precise correction required for rapid re-entry. More proactive methods rely on deeper reading propagation resistivity and real time modeling to avoid exiting the reservoir altogether. In recent years more advanced proactive methods in the form of azimuthal wave resistivity have gained rapid acceptance. Being azimuthal in nature and deep reaching they anticipate reservoir exits well before they occur and advise in real time the most favorable change of direction to stay within the confines of the reservoir. As the well progresses, interactive software lets the geologist update the subsurface model with the new information. In some types of reservoirs, additional data on oil viscosity, pore pressure and drilled rock properties help further improve critical geosteering decisions.
