Paper Number: URTEC-4036768-MS
... with the presence of geological structures such as faults, the stress evolution and its effect on infill well fracturing can become more complicated, since the presence of faults can increase the heterogeneity in stress fields and faults can be more permeable than the rock matrix. To better understand the stress...

... deep with a loading rate of 100 nm/s, a hold time of 5 s at the maximum indentation depth, and an unloading rate of 100 nm/s. An indentation depth of 1 5 m probes shale as a heterogeneous phase, as opposed to indentation depths shallower than 1 m that would likely probe single minerals (Bennett et...

... Abstract Measurements of UCS in ten Austin Chalk cores located from south Texas to eastern Louisiana are heterogeneous and vary by lithofacies. Chalk-rich facies, which are higher in %Ca and lower in %Al and %Si, have higher UCS than the argillaceous clay-rich strata. This observation...

... in over the past years. When run before fracturing in an open hole, it highlights formation heterogeneities and helps selection of the best zones to be fracked. If run after fracturing in a cased hole, this new type of log acquisition can be considered as a PLT proxy for identifying the producing clusters...

... of heterogeneity of imbibition in shale samples. The dynamic processes of water imbibition in the 1-inch (25.4 mm) core sample were explicitly demonstrated, and the imbibition along the matrix and imbibition through microfractures is distinguished through neutron radiography image analysis. The causes of observed...
