Offshore drilling rigs operate in very sensitive environments surrounded by water. Waves can wash seawater onto the rig. Monsoons can completely cover the deck with a thick layer of water within a couple of minutes. Oil spillages can end up on the drill floor because of a mistake or a mechanical failure.
A field method for measuring solids sizes on the job. It is simple and easy to use and should improve the efficiency of solids control. There will be some sacrifice in accuracy; however, only the relative weight percentage distribution of the particles is needed to allow constructive steps to remove these particles.
Oil slop & sludge waste equipment manufactured by aipu solids control are working on Karamay, Xinjiang Uygur Autonomous Region, China.
Much of the drilling in unconventional resource plays occurs in unstable shales, which are usually fractured and can be easily destabilized. Successful drilling through them can be difficult at best, and many high-angled holes in these plays are often lost due to mechanical instability. This paper looks at the drilling problems of shale gas drilling from the theoretical perspective of Wellbore Pressure Management, (WPM) and keys in on the effects of Equivalent Circulating Density (ECD) while drilling and on the effects of Equivalent Static Density (ESD) when there is no circulation.
