Use this Drilling Log to effectively chronicle a drilling activity. Document the drilling depth, subsurface formation properties, and the various events encountered during a drill and include any corresponding notes. Collect qualitative data including visual geological characteristics as well as quantitative logging measurements such as resistivity, porosity, and gamma ray (GR) readings obtained from density, neutron, and sonic tools. This logging app is customizable to suit any drill measurement requirements and will work in both on and offline environments.
