Title: Value of Well Samples and Cores as Exploration Tool: ABSTRACT

Author(s): J. Rulie Taylor

Article Type: Meeting abstract


Due to the decreasing number of unexplored structural traps, survival of the exploration effort in the oil industry depends on an increased emphasis on stratigraphically trapped oil. Detailed descriptions of rock properties from well cuttings and cores is the basic tool for the delineation of favorable stratigraphic accumulations. Any complete stratigraphic analysis of an area must include not only the facies and thickness relationships but also such parameters as the relationship of oil occurrence to facies, sedimentary structures and environments, and the geometry and pore space distribution of potential reservoirs. Well samples and cores are the best tool for both a qualitative and quantitative definition of these relationships. Rock properties from samples and cores c upled with fluid and pressure data from mechanical logs and testing information equip the geologist with all the necessary information to delimit favorable stratigraphic areas for hydrocarbon accumulation.

The value of the information that can be gained from well samples and cores is directly proportional to the quality of the samples and cores. The geologist has a responsibility not only to his employer but also to the whole oil industry to see that adequate steps are taken to secure and to store usable well cuttings and cores.
