Funding for this work was provided by Benchmark Oil and Gas, Pioneer Natural Resources, Chevron North American Exploration and Production Company, and the State of Alaska.
This data set was created to provide sample collection location as well as summarize descriptions of the samples, such as the formation from which they were collected, and a brief physical description of the sample.

Data sources used in this process:
Data sources used in this process:
The latitude and longitude values in this report were collected with handheld GPS units which are accurate to approximately 4 meters. Formation names were interpreted on the basis of prior geologic mapping. To facilitate accurate analysis care was taken to collect fresh, unweathered, fracture-free samples that appeared to be representative of low-permeability lithologies cropping out within the field area. PetroTech Associates did not provide documentation of per/sample or general procedural error ranges, however, more information regarding their analytical procedures can be found in the process steps section (below).
The horizontal position accuracy on point data is approximately 4 meters based on the error range in the handheld GPS units used to collect spatial information.
This dataset includes all samples submitted for MICP analysis.
No topologic relationships are present in this data set.
