... of investigation (DOI). Comparison between the responses of sensors having different DOI over multiple logging passes can be used to assess wellbore deterioration over time. Emerging tools like ultrasonic LWD imagers provide high-resolution, azimuthal hole-size measurements allowing advanced evaluation of wellbore...

... Abstract In this work, we use the theory of multi-porosity multi-permeability porothermoelasticity to derive the analytical solutions of pore pressure and stresses for an inclined wellbore, accounting for a rate-dependent mud cake buildup on the wellbore wall. The solutions are further combined...

...Echo meter Echometer has been tried so far in five wells and the objective is to perform acoustic logging in order to identify liquid loading issues and to detect restrictions caused by Halite formation in the wellbore. The following measurements are achieved from the trial...

... of the wellbore during losses are influenced by multiple factors such as wellbore geometry, downhole fluid properties, free-fall (during cementing), details of the unknown loss zone geometry, as well as the features of the loss circulation material (LCM) ( i.e. material, particle size distribution, density etc...

.... The steep initial production declines in these reservoirs are influenced by matrix-fracture transients, near-wellbore damage / production impairment, and factors that that cause the natural fracture conductivity to change (decrease) during the production. In this paper we focused on the simulation...

... Abstract Multistage hydraulic fracturing is an effective stimulation method as it opens communication between the wellbore and larger reservoir volumes. Nevertheless, there are cases where the formation cannot be fractured within the completion pressure limitations. This problem can...

... Abstract The applied forces on the wellbore axis lead to stress and strain concentration around it. These resultant stresses and strains will develop in the preferred orientation depending on the stress fault regime and will cause a rock failure in that direction. When these forces exceed...

... Abstract Near-wellbore fracture diversion is a common means of achieving uniform stimulation in long wellbores through heterogeneous reservoirs. A novel sequenced fracturing technique using self-degradable, nondamaging, multimodal particulate pills was deployed for the first time in a clastic...

After about 500 ft of drilling, the target reservoir layer was identified below the wellbore, and the well was steered into it. The NMR initially...

... Abstract With the significant increase in multistage hydraulic fracturing in the last two decades, occurrence of casing failures has also become noticeable, raising wellbore integrity concerns among operators worldwide. The consequences of casing failures can be varied, but in many cases...
