Detailed examination of Geoscience data is important in research, development and discoveries of new hydrocarbon reservoirs and mineral deposits critical to North America's energy security and independence as well as the Commonwealth of Kentucky. Preservation of Geoscience data will impact future generations, it helps in the training and educating of the next generation, and the evaluation of water resources, environmental issues and potential geohazards. Geoscience data also provides opportunities for redevelopment of mature oil and gas fields and mineral deposits resulting in more investment in the community, creation of more jobs, an infrastructure resulting in sustained economic growth, and increased tax revenues. It also lowers exploration cost, and increases efficiency and safety.

deformed structures, chemical alteration, mineralogy, fossil content, oil staining, and rock types.

Conclusions reached using Geoscience data provides information to government and industry, allowing intelligent planning decisions concerning assessment and management of valuable natural and strategic resources. Without this data, more resources will be consumed in duplicated exploration and development and there would be a greater chance of failure because of increased cost overrides and decreased production. Intelligent planning decisions are based on data. Without good and efficient management of current and future resources, economic development cannot be sustained. Geoscience data provides solutions to scientific, economic, and environmental issues and potentially to natural disasters.

Although many tools are available for exploration, the examination of cores and well samples is the greatest single source of information for hydrocarbon and mineral exploration and stratigraphic and structural investigations. Cores and well samples also are the best source of detailed geologic information about the nature, occurrence, and extent of rocks in the subsurface. Geologists engaged in the exploration for and development of Kentucky's mineral resources must have detailed knowledge about the strata in which the deposits occur, as well as information about associated deposits. Cores and well samples also provide essential information for a better understanding of our groundwater resources and related environmental problems. This knowledge of rock beneath the earth's surface can only be gained through detailed examination of well cuttings and cores.


Various features found in core samples at KGS Well Sample and Core Library.

Geoscience data provides opportunities to conduct research, development and exploration leading to new discoveries. In addition, an established record results in greater scientific success and predictability. Also, less development and exploration time, lower exploration cost, increased efficiency and greater safety. Some data is irreplaceable and will be cost prohibitive to reacquire in the future. Data will be available to rework old reservoirs, reevaluate environmental concerns and predict natural hazards using new technology and new extraction enhancement techniques. This will ensure continued economic prosperity, and energy independence resulting in greater national security. It is imperative that training and educating the next generation take place, as knowledge is the key to success. The Kentucky Geological Survey, Well Sample and Core Library retains in its collection over 22 million vertical feet of cores and well samples.
