摘要： Methods are provided for determining the location and height of cement in a subterranean borehole region using pulsed neutron capture (PNC) logging tools. The methods include obtaining a pre-cementing data set, placing in the borehole region a cement slurry that includes a liquid a thermal neutron absorbing material, obtaining a post-cementing data set, comparing the pre-cementing data set and the post-cementing data set to determine the location of the cement, and correlating the location of the cement to a depth measurement of the borehole to determine the location and height of the cement placed in the borehole region.

摘要： A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole tool. The method also includes pumping a first proppant into the wellbore after the first set of data is obtained. The first proppant includes a first tracer that is not radioactive. The method also includes pumping a second proppant into the wellbore. The second proppant includes a second tracer that is not radioactive. The second tracer is different than the first tracer. The first proppant and the second proppant flow into fractures in the wellbore. The method also includes obtaining a second set of data in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The method also includes comparing the first and second sets of data.

摘要： The present disclosure is directed to methods for evaluating a gravel pack, a frac-pack, or cement in a wellbore. In at least one embodiment, a method for evaluating a gravel pack, frac-pack or cement in a wellbore, includes pumping a first material into the wellbore, wherein the first material comprises a first tracer that is not radioactive. The method includes pumping a second material into the wellbore, wherein the second material comprises a second tracer that is not radioactive. The method includes obtaining a set of data using the downhole tool in the wellbore after the first and second materials are pumped into the wellbore. The method includes obtaining a baseline using the downhole tool in the wellbore in a depth interval without the first or second material. The method includes comparing the set of data with the baseline.

摘要： Methods for logging a well utilizing natural radioactivity originating from clay based particulates are disclosed. The methods can include utilizing a gravel pack slurry containing a liquid and gravel pack particles to hydraulically place the particles into a gravel pack zone of a borehole penetrating a subterranean formation and obtaining a post gravel pack data set by lowering into the borehole traversing the subterranean formation a gamma ray detector and detecting gamma rays resulting from a native radioactivity of the gravel pack particles. The methods can further include using the post gravel pack data set to determine a location of the gravel pack particles and correlating the location of the gravel-pack particles to a depth measurement of the borehole to determine the location, height, and/or percent fill of gravel-pack particles placed in the gravel pack zone of the borehole.

摘要： Methods of using capture gamma-ray spectroscopy for analyzing gravel-packs, frac-packs, and cement are disclosed herein. The methods can include distinguishing particles placed in a borehole region from particles placed in a subterranean formation outside of the borehole region, by utilizing a slurry comprising a liquid, particles, and a thermal neutron absorbing material to place the particles into the borehole region. The methods can also include obtaining first and second data sets by lowering into a borehole traversing the borehole region a pulsed neutron logging tool comprising a pulsed neutron source and a detector, emitting pulses of neutrons from the pulsed neutron source into the borehole region at intervals of one pulse per about 1,000 μsec for the first data set and about one pulse per about 100 μsec for the second data set, and detecting capture gamma rays resulting from nuclear reactions in the borehole and the subterranean formation.
