Application of quantitative crosspiot technique in fluid identification.;

High sensitive fluid identification based on seismic data.;

Non-intrusion line method for fluid identification and its application in low permeability and low resistivity reservoirs;

Based on the low permeability reservoirs in HN Oilfield of Tuha Oilfield, a method for reservoir fluid recognition is established based on dual resistivity ratio by using the different factors of the principles of dual-lateral and dual induction logging and its difference to fluid sensitivity.
