There are many factors that impact on hole cleaning while drilling directional wells for
hydrocarbon recovery. Those that are most prevalent include: annular drilling fluid velocity …

A series of complex production wells have been applied in challenging reservoirs to
maximize oil recovery. Multilateral horizontal well has received plentiful attentions in recent …

Drilling multiple-lateral wells and employing intelligent completion systems would very likely
lead to considerably higher productivity and increased recovery at relatively low incremental …

This study presents a 3D analytical model to analyze the transient flow into multilateral
horizontal wells. The model considers arbitrary phasing angle, selective lateral completion …

One of the common assumptions used in horizontal-well interference test analysis is to
ignore fluid flow in an out of the horizontal observation well and represent it by an …

An analytical model for predicting the productivity of Radial-lateral wells (RLW) drilled using
radial jet drilling technology was developed in this work. The model assumes uniformly …

Drilling problems frequently result from severe mechanical failure of the wellbore wall and
thus depend on the interplay between the magnitude and orientation of in situ stresses, rock …

Multilateral wells were used in the petroleum industry to increase hydrocarbon recovery from
oil and gas fields as a cost effective technology. The objective of this study is to develop new …

In this study, the pressure drop obtained from physical experiments and theoretical
approaches of a single horizontal wellbore is reviewed and a comprehensive wellbore …

In order to improve the combined exploitation efficiency of horizontal and vertical wells, and
given the fact that the complex and varied spatial structure of sand bodies in the Fuyu oil …
