Subsurface Maps
Subsurface maps dictate well placement and enable engineers to calculate reserves and monitor trends in reservoir performance. Geologists play a key role in subsurface mapping by using interpretations of depositional environments and diagenetic events to project reservoir data away from relatively few well control points. In this sense, subsurface mapping is in great contrast to geological mapping of the earth’s surfaces.
Aerial Photography
Aerial photography became an important part of the mapmaking process in the twentieth century. Aerial photographs provide a straightforward depiction of the physical and cultural landscape of an area at a given time. When skillfully interpreted, these aerial images supply geographers, historians, ecologists, geologists, urban planners, archaeologists, and other professionals with a pictorial basis often critical to their studies.
Augering & Boreholes
Augers primarily are used for general exploration, advancing and cleaning the borehole, and drilling accessible borings. Augers also are used for various construction operations, such as drilling drainage wells and excavating for piers and caissons. Disturbed or undisturbed samples can be obtained from boreholes advanced by augering methods. However, disturbed samples may not be representative of the in situ deposit because materials may have segregated during the augering process or may have been contaminated with soils from different depths.
