Inadequate hole-cleaning in an annulus leads to several problems such as mechanical pipe
sticking, premature bit wear, formation fracturing, and/or slow drilling. However, the literature …

The article studies the formation features of the bottomhole zones in productive formations
during operation of production wells in the north of the Perm Territory. Their distinctive …

This study conducted a radial flow experiment to investigate the existence of non-Darcy flow
and calculate the non-Darcy “inertia” coefficient; the experiment was performed on seven …

Type-curve analysis on flowback and production data is a powerful tool in characterizing
hydraulic fractures (HF) and reservoir properties. In order to evaluate HF characteristics and …

Accurate and speedy determination of pressure drop during cuttings transport is an
important aspect of a drilling operation. However, the literature suggests that there is a lack …

In this paper, we present a computational fluid dynamics (CFD) model to perform single-and
two-phase fluid flow simulation on two-and three-dimensional perforated porous media with …

The reservoir productivity index depends on the performance of fluid flow through the
perforation tunnels. Experimentally, it is observed that higher fluid flow rate occurs in …

В статье представлены результаты анализа геологического строения отложений
фаменского яруса девонской системы на территории Пермского края. Выполнено …

An oil well's productivity is generally considered the standard measure of the well's
performance. However, productivity depends on several factors, including fluid …

A number of different factors can affect flow performance in perforated completions, such as
perforation density, perforation damage, and tunnel geometry. In perforation damage, any …
