What difference does sampling density have on the results of the survey?
We prefer to sample an area on a ¼ by ¼ mile grid pattern, or 0.5 by 0.5 km if working in metric system. That is the most economical method to provide the type of results we feel are best suited to a client’s needs. If the area to be surveyed is large and an exploratory survey is desired, we recommend a mile by mile survey with samples collected every 1/4 mile. The grid pattern really depends on the size of the hydrocarbon deposit you expect to find. If you are looking for a meandering deposit 800 yd. wide, we need to use at least a ¼ by ¼ spacing pattern, while when looking for bigger deposits in the S. American jungles, we can open the grid pattern.
