... et al., 2005; Abbas et al., 2019). The most common manifestations of wellbore instability are collapse and leakage. However, proactive determination of critical mud weights can often mitigate these drilling issues. To achieve this, a constitutive model is employed to estimate the stresses surrounding...

... ABSTRACT: The potential for activating faults associated with geologic carbon sequestration is an issue of concern both related to induced seismicity and CO 2 leakage. Faults are usually simplified (e.g., single, planar and homogeneous) in numerical simulations for the sake of computational...

... ABSTRACT: Seismic data is often used to predict the risk of leakage. Seismic attributes are data derived from original seismic data. Different seismic attributes have different responses to the risk of leakage. In this paper, a prediction model of mud loss probability based on different kinds...

... and leakage pressure calculation model is proposed. The calculation result of leakage pressure is taken as the physical constraint condition, and the deep neural network model based on machine learning is combined to predict the probability of downhole mud leakage risk. By comparing the relationship between...
