Cost reduction is a driving force in the development of brownfield wells.1 It is well known that better planning leads to better execution in the drilling phase with less nonproductive time and reduced costs. This paper describes enhanced well planning workflows in light of recent software technological innovations. The technology, which enables this solution for the first time in the industry,...
Rotational drilling was a revolution in drilling technology. It made the drilling process more efficient and faster and more depth of well could be achieved through rotation method. Besides all of its advantages, the rotation approach induced some problems like pipe sticking and downhole cleaning to the drilling procedure. Hole cleaning and reduction of torque and drag seems to be vital in incl...
OBJECTIVE To evaluate the outcome of ovarian needle drilling using transvaginal ultrasound guidance as an alternative to the traditional laparoscopic electrosurgical drilling for patients with polycystic ovary syndrome (PCOS). DESIGN A randomized controlled study. SETTING University teaching hospital and private practice setting. PATIENT(S) The study comprised 163 patients with clomiphene...

K e y w o r d s F o u r t h g r a d e fluid, Unsteady flow, Lie symmetries. 1. I N T R O D U C T I O N In recent years, considerable efforts have been usefully devoted to the s tudy of flow of nonNewton ian fluids. This is ma in ly due to their m a n y appl icat ions in pe t ro leum drilling, manufactu r ing of food and paper, and other similar activities. A vast a m o u n t of l i te ra ture i...
This paper examines the diverse nature of user reactions to information technology (IT) within the social-historical context of its organizational use. Employing activity theory as a conceptual framework, we conduct an interpretive analysis of physicians work, perceptions, and IT usage experience at a large community hospital to understand why some of these physicians were favorably disposed to...

The process of borehole drilling is a nonlinear and many dimensional process. During drilling it is possible occurrence of some complications (for example transition of drilling tool in layer with anomalous pressure). New method of identification of rock layers with anomalous pressure was proposed and tested on real plant data.
