... for developing these lower Wilcox reservoirs referred to as a High Angle Multi Fractured (HAMF) well design concept. The value of the HAMF concept was assessed via reservoir modeling to understand it's value for low mobility reservoirs. Supporting evidence on the EUR uplift from analogue field studies...

... on gas and condensate mobility during CO2 H-n-P injection. Laboratory PVT tests were performed to generate relevant data sets that describe the complex phase behavior changes when CO2 interacts with gas condensate systems. These data sets were applied for EOS tuning, phase behavior prediction...

Abstract In this study, a comprehensive workflow of estimating formation mobility using Acoustic Stoneley wave was evaluated, with diverse subsurface conditions and drilling environments including hole size, mud type, formation lithology, and formation fluids. The outcome of this exercise aimed...

Results demonstrated that the joint effect of Stern layer ion concentration and corresponding mobility dominates sub-MHz dielectric response of rocks. The low-frequency permittivity enhancement due to the EDL can sweep several...

The model for dispersed clays incorporates the effects of clay geometry and demonstrates that the conductivity is intimately related to the geometry and length scales involved in the clay conduction. The increase in the effective clay-counter ion mobility...

... characterization. By observing pressure behavior versus time in a pretest, one can directly measure fluid mobility at discrete stations. We can then use the measured fluid mobility to calibrate S 0 clay and compute a continuous permeability log. Here is the workflow: Zone the well such that the clay...

... approximately 30 pore volumes of gas has been injected, foam still reduced gas mobility in the treated layer by about a factor of 9. We base this estimate on the decrease of injection into the treated layer and the increase into the other layers; the results are consistent among the layers. After 35 and 152...
