he latest addition to SPE’s Monograph Series, Low Invasion Coring will help readers develop an understanding of how to apply the array of technologies required for successful completion of a low-invasion coring (LIC) project. This monograph addresses the principles of obtaining low-invasion cores and provides essential practical tips for engineering field LIC projects. Appendices provide detailed information on specific core-analysis procedures. .

Contents: Preplanning • Low-invasion coring bit selection • Other downhole hardware • Low-invasion coring fluids • Rigsite operations • Coring poorly consolidated sandstone • Core analysis • Appendices include: Selected SPE papers concerning LIC technologies • Special circumstances—sponge coring and the use of noninvading core gel • Impact of oil-based mud on connate water saturation and other rock properties
