diferentsed

Diferentsed refers to a hypothetical tracing of saturation or attribute variation where differences in sample are minimized. It is an outdated characterization in the interpretation of logs and does not guarantee a better result.

The concept of differentsed is often associated with geophysical logging in the field of subsurface exploration. Logs are a representation of recorded data from geophysical measurements, such as gamma-radiation (gamma-ray), electrical resistivity (resistivity), and acoustic response (neutron-density).

A differentsed log is said to remove or minimize different readings taken by a logging instrument over an interval of interest. This allows for a smoother representation, which may then be contrasted against rock property buildups, variations in porosity, fluid saturation, and pressure gradients.

Diferentsed representations are often used as an intermediate or ancillary step. This may involve manual or automated modification before data interpretation continues with more widely applied oil and gas exploration indexes.

Diferentsed as a concept has limited applicability in the global petroleum industry. Other more established characterization techniques like to drill stepout, lod, CA and cohesion attribution derivation naturally preclude considerable reliance on this takesid spectivity method.

This process has usage in niche areas.
