摘要： A method for real-time formation assessment using a multi-component induction logging tool includes conveying a multi-component induction (MCI) logging tool along a borehole through a formation. The method further includes determining a relative dip and a relative azimuth of the formation based on data from the MCI logging tool. The method further includes calculating true dip and true azimuth of the formation based on the relative dip and the relative azimuth. The method further includes assessing the quality of the true dip and the true azimuth calculations.

摘要： An NMR logging system is disclosed which continues logging without interruption despite switching activation sets to adapt to changes in formation properties. Based on detection of an approaching or encountered geological boundary, an appropriate activation set is transmitted to the downhole NMR tool while the NMR tool continues logging. This system optimizes NMR data collection for each formation and associated formation fluid properties while reducing the need to stop the tool string movement while switching the activation set, and reduces incomplete collection of NMR and non-NMR logging tool data.
