... demonstrates that, in several subsea scenarios, a relatively small error in the experimental fluid PVT data can lead to significant variation in APB estimation. The ML-based models for “density = f ( T , P )” for the fluids ensure that the cumulative error during the modeling process is minimized. The use...

Further, we found qualitatively very good correlations between seepage-test results and the log results for the bond between cement...
