... down the temperature of the cutting edge by 20%, as calculated analytically. Another major change that can affect the results is hydraulic design of the bit, which includes the location of the nozzles as well as their orientation and size. In test cases, the cooling rate improved by 50% while keeping...

... to layers close to water zones. – Bypassing near wellbore formation damage. P 2 is the pressure of surrounding fluid at point "2" after the nozzle. v 1 is the fluid velocity inside the jet at point "1" before the nozzle, which is almost zero. v 2 is the jet stream's velocity...

... efficiency, in terms of the percentage of mud or cement in a control volume as a function of time, depends on perforation size and density, nozzle size/number, flow rate, fluid properties, as the ROP/BHA pulling speed and tool RPM. Key findings from a parametric study to optimize these parameters...

This paper introduces a new downhole constant flow nozzle which can keep zonal flowrate constant under the condition of pressure change. And the flowrate can be adjustable...

... Abstract Recently high pressure water jet drilling is proposed for coalbed methane development by connecting nozzle with coiled tubing directly. However, rock breaking efficiency is still compromised because of the hydraulic energy loss when water flows through the small size coiled tubing...

...-separator is a low-temperature supersonic separator, based on natural gas cooling in a supersonic swirling flow. Supersonic flow is implemented using a convergent-divergent Laval nozzle. In this nozzle, rapid cooling of gas takes place due to the conversion of flow potential energy into kinetic energy...

A new electronic control water flooding technology is presented in this paper. Powered by DC battery, the system has a gear...

... these conditions experienced reamer nozzle erosion. To temporarily solve the problem three reamer nozzles were blank-out. While this did produce an immediate solution it forced rig personnel to activate the reamer at the surface leading to a dedicated trip for drilling out. Blanking out the nozzles also reduced...
