Gas coning is a tendency of the gas to impel the oil downward in an inverse cone contour toward the well perforations. Once the gas reaches the well, gas production will dominate the well flow and the oil production will hence significantly decrease. From an economical and operational standpoint this condition is undesirable since the gas price is much lower than the oil price, and the gas hand...

This is a summary of state of the art horizontal well technology and a review of the economic benefits of horizontal wells. The paper describes various reservoir applications of horizontal wells from primary recovery to EOR applications. The paper includes field examples of different applications. . Although horizontal wells have been drilled as early as 1927, the major thrust of drilling horiz...

Time-equispaced inertial measurements are practically used as inputs for motion determination. Polynomial interpolation is a common technique of recovering the gyroscope signal but subject to fundamentally numerical stability problem due Runge effect on equispaced samples. This paper reviews theoretical results phenomenon in related areas and proposes straightforward borrowing-and-cutting (BAC)...

The paper focuses on the loads applied to helicopter blade cross-sections in multibody dynamics system. main objective is simplify aerodynamics calculation and avoid time-consuming CFD methods. For this reason, way of computing proposed by using methods with a linear-elastic model. As primary tool for further research, MCS Adams software package selected. Splitting rotor into finite number sect...

The treatment is described of 17 patients with presumed viral hepatitis who developed hepatic coma unresponsive to standard conservative measures. Five patients were considered for treatment by exchange transfusion. Four were treated, with transient improvement in two, but all died. Nine patients were considered for treatment by heterologous liver perfusion. Six were treated, with transient imp...

Code coning is considered as the challenge to the software quality. To develop a reliable and authenticated software system, it is required to remove the clone based bugs over the software system. There are number of associated approaches but no one is able to provide the reliable solution. In this work, a combined mathematical model is presented to overcome the limitations of existing approach...
