Study the effect of temperature Salt drilling fluids on production Casing

This research aims to decrease the cost of last production stages through decreasing the cost of potential casing repair by avoiding the problems that casing string may be exposed to. Such problems are caused by the temperature effect of salt drilling fluids as well as other fluids normally existed in the annular behind casing at the nonecemented intervals.

Study Of Drilling Fluid Effect On The Production Casing

This research aims to increase the production lifetime of oil and gas wells through avoiding the problems that production casing string may be exposed to. Such problems are caused by the effect of different drilling fluids as well as other fluids normally existed in the annular behind casing at the none-cemented intervals.

The computer modeling and studying the trans case for moving the fluids in the long pipe

It is a cross in the hydraulic systems with long pipes case modeling of the hardest and most important cases in search. Of the most important and is considered Query to achieve study the changing resistance model is used to describe the changing liquid flow in the tube. As described by knowing the nature of the shear stress to the pipe wall and also know the nature of the flow ( laminar or turbulent ). The results of simulations of hydraulice shock caused by the sadden move of the hydraulic control valve which studied in the following cases: 1- Hard to improve the discharge of the pump rate. 2- Improve the discharge of the pump variable rate finally; compare the results of computer simulations with experimental results.

An-In-Vivo Comparison Study of The Effect of Some Materials Which Used in The Treatment of Infected Root Canals

This study aims to evaluat of the effect antibacterial for some materials which are used dressing and irrigating fluids in infected root canal then compare of the effectiveness of each of The irrigating fluids and materials used Dressing in infected root canal The sample of study was 90 cases a single infection root canal , were divided into three group and applied to the total of each such substance(calcium hydroxide with sodium hypochlorite ,calcium hydroxide with Iodoform, chx) and then conducted the transplant bacterial. The cases were evaluated in terms of results of bacterial culture. The study showed that chx best antidote infection of calcium hydroxide with sodium hypochlorite and calcium hydroxide with Iodoform
