Cunningham is vice president in charge of the regional section of the Atlanta Fed's research department. Mancuso is an analyst in the regional section. They thank Jimmy Stone of Stone Energy, David Guidry of Guico Machine Works, and Frank King and Will Roberds for insightful discussion and comments. Shocks are mostly of concern when the potential outcome is bad. The most infamous example of a n...

About 90% of the world’s natural gas hydrates (NGH) exist in deep-sea formations, a new energy source with great potential for exploitation. There is distance from threshold commercial exploitation based on single well currently used. The complex structure an efficient and advanced drilling technology. improvement NGH productivity through various wells unclear, there no more complete combing. T...

The main affecting parameter for Delamination of the composites and in turn the failure of composites is the Thrust force. In the present work an attempt has been made in order to investigate the Thrust force generated during drilling of the TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and3%. A plan of exper...

BACKGROUND AND PURPOSE Because acute ischemic strokes (ISs) are mainly hospitalized, hospital discharge data could be used to routinely follow their incidence management. We aimed to assess sensitivity and positive predictive value of the French hospital discharge database (HDD) to identify patients with acute IS using a prospective and exhaustive cohort (AVC69) of acute IS cases. METHODS A s...

This paper describes the areal density (bits per unit area) roadmap goals for tape based magnetic recording (TAPE) and uses these goals as counterpoints for the areal density roadmap strategies for Hard Disk Drive (HDD) and NAND flash. Technology comparisons described in this paper will show that presently volumetric densities (bits per unit volume) for TAPE, HDD, and NAND are similar and that ...

Horizontal wells are proven to be better producers because they can be extended for a long distance in the pay zone. Engineers have the technical means to forecast the well productivity for a given horizontal length. However, experiences have shown that the actual production rate is often significantly less than that of forecasted. It is a difficult task, if not impossible to identify the real ...

The growth of Indian manufacturing sector depends largely on its productivity & quality. Productivity can be improved by reducing the total machining time, combining the operations etc. In case of mass production where variety of jobs is less and quantity to be produced is huge, it is very essential to produce the job at a faster rate. This is not possible if we carry out the production by usin...

This paper details the online-identification-based adaptive design of a stick/slip minimization algorithm and top-drive servo control for Rotary Steerable System (RSS) directional drilling tools. Stick/slip in this context refers to the downhole angular velocity variation of the bit about a nominal value. The basic pole placement controller designs are SISO linear but recursively evaluated base...
