Cased hole water saturation conditions are more complicated versus open hole as the sensors measure through the casing/tubing and cement thicknesses. Traditionally the pulsed neutron tools were used to provide the formation sigma (Σ) and carbon/oxygen (C/O) ratios. The cased hole formation resistivity (CHFR) was introduced in year 2000.

The latest technology, known as new generation pulsed neutron tool was made available in 2017. The principles and applications of all methods are discussed including regional case studies demonstrating the benefits and impact to the field development. Saturation determination practical steps are also presented for in tubing completions. More activities are being carried out in cased hole operations, due to the low oil price outlook. The goal is to produce more hydrocarbon from the mature fields at lower costs. These practices prove good timing to discuss and review the traditional versus the new technology used in cased hole water saturation measurements. The applications include evaluation of bypassed pay, alternative to lack of open hole data due to difficult well conditions, reservoir monitoring with time-lapse analysis, risk and cost minimization through planned cased hole logging providing important benefits to the petroleum industry.
