.... This allows the proper estimation of microannulus thickness downhole using ultrasonic log data. Next, the obtained value is used as input to Poiseuille’s equation for the final behind casing flow rate estimation. The model also relies on the pressure drop along the considered vertical portion, it is corrected...

... value. If the sandstones contain potassium-rich micas and feldspars or heavy minerals rich in thorium or uranium, their radioactivity increases and the gamma ray cutoff increases accordingly. The increased radioactivity can make the sandstone reservoirs look like shaly formations, and the estimation...

... evolution is an essential step for several reasons. Among the most important ones, there are the estimation the reservoir efficiency and the estimation of some of its dynamic properties. The internal structure of reservoir rocks is traditionally investigated using thin sections that are prepared so...

In complex reservoir scenarios, the standard well test interpretation lacks a direct link with the actual flowing thickness of the reservoir rock and this represents the major cause of inaccurate permeability estimations. Moreover, an a-priori knowledge of fluid flow path through the porous...
