Radial Filtration of Drilling Mud

Journal of Petroleum Technology, 1952
Abstract A laboratory investigation has been made of the effects of mud hydraulics upon the formation and erosion of mud filter cakes. The tests were conducted to simulate drilling conditions as nearly as possible.

Radial Filtration of Drilling Muds

Transactions of the AIME, 1940
It is generally recognized that fluid is lost from rotary drilling muds topermeable strata during normal drilling operations; but that this fluid is thefiltrate from the mud, rather than the mud itself, has been shown by variousworkers. The presence of this filtrate in oil-bearing or gas-bearing strata isundesirable and harmful.

Application of Electrical Automation Technology in Radial Drilling Machine

2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021
Radial drilling machine is an important equipment in metal workpiece processing, which is widely used. Traditional machine tools use AC contactor to build control system, and the control system of AC contactor is huge. Therefore, the reliability is poor, the working life of electrical components is short, and it brings difficulties to repair and ...

Radial Jet Drilling: A Technical Review

SPE Middle East Oil & Gas Show and Conference, 2017
Abstract Radial jet drilling, RJD is an unconventional drilling technique that uses the jet energy of high velocity fluids to drill laterals with different geometries in both conventional and unconventional reservoirs. Many case studies are available worldwide have proven RJD as a viable alternative to traditional stimulation techniques,

Slim Hole Multiple Radials Drilled with Coiled Tubing

SPE Latin America Petroleum Engineering Conference, 1992
Abstract Two methods of combining water jet drilling and coiled tubing, the Ultrashort Radius Radial System (URRS) and the Quick Radial System (QRS), are described. Both provide multiple horizontal radials on a single horizon from a single vertical wellbore to penetrate near wellbore damage.

Interconnect microvia drilling with a radially polarized laser beam

Journal of Micromechanics and Microengineering, 2006
High-density interconnection via drilling using a diode-pumped solid-state laser is one of the industrially accepted techniques for 3D packaging and backside contacting applications. The advancement in microelectronic systems requires this technique to be improved constantly. In this paper, we introduce the technique of applying a radially polarized UV
