Title:
Mercury injection capillary pressure results from outcrop samples in the Indecision Creek Member of the Naknek Formation and the Kaguyak Formation type section
Abstract:
The State of Alaska Division of Geological & Geophysical Surveys (DGGS) is currently engaged in a multi-year study of the hydrocarbon potential of the Tertiary and Mesozoic strata in Cook Inlet basin. This report summarizes mercury injection capillary pressure (MICP) data for 19 samples collected from the Indecision Creek Member of the Naknek Formation and the Kaguyak Formation type section. All samples were analyzed by PetroTech Associates, Houston, TX. PetroTech Associates found that the Kaguyak rocks were generally less porous and permeable compared to the Naknek, although there is some overlap in values. The capillary pressure data for this publication is provided in its native spreadsheet format. The manuscript provides correspondence from PetroTech Associates describing the methods used in MICP analyses of the samples in this report, a brief summary of the data, and references cited.

Why was the data set created?

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) is currently engaged in a multi-year study of the hydrocarbon potential of the Tertiary and Mesozoic strata in Cook Inlet basin. This report summarizes mercury injection capillary pressure (MICP) data for 19 samples collected from the Indecision Creek Member of the Naknek Formation and the Kaguyak Formation type section. All samples were analyzed by PetroTech Associates, Houston, TX. The capillary pressure data for this publication is provided in its native spreadsheet format. The manuscript provides correspondence from PetroTech Associates describing the methods used in MICP analyses of the samples in this report, a brief summary of the data, and references cited.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 2012 (process 1 of 2)
    Sample collection - Samples were collected from the Indecision Creek Member of the Naknek Formation and the Kaguyak Formation type section. With the exception of sample 12MAW121-b, samples were collected from measured stratigraphic sections.

    Date: 2012 (process 2 of 2)
    Mercury injection capillary pressure analysis - Samples were submitted to PetroTech Associates, Houston, TX for mercury injection capillary pressure analysis. Following receipt of the samples, a representative portion of each was trimmed to fit the sample holders and examined under reflected light microscopy to note any irregularities that might affect the data quality. The rock surfaces were cleaned of any mold or dust and the samples then dried to a constant weight in a low temperature oven before being analyzed. During capillary pressure testing , the volume of mercury injected was measured at 118 pressure points from 1.64 to 59,500 psia. These data were then corrected for closure. The "closure" volume is the amount of mercury intrusion that occurs as the mercury conforms to the sample surface, filling any irregularities, prior to entering the pore system. The resultant data and comparative plots are provided in this data release. See manuscript for references.
