Abstract
During the evolution of developing unconventional resources, large variability in production has pushed the industry to look at combining key petrophysical factors to gain insight into the production contributions of each stage in a completion design. Along the wellbore, petrophysical variabilities are minimized while the completions operation and design are optimized by placing the well in the target zone with minimal wellbore tortuosity.
Landing point identification and horizontal well placement using inorganic and organic elemental data acquired from drill cuttings and advanced mud-gas analysis at the wellsite, combined with LWD gamma ray spectroscopy enhances well placement decisions by providing a comprehensive near real-time chemostratigraphic interpretation. This is achieved while also maximizing petrophysical integration efficiency for well completion designs.
