Ultrasound flow detection is a typical non-intrusive flow detection method; however, mud drilling will cause ultrasound attenuation, and the common ultrasound detection method cannot detect effective echo signals.
• Specific exposures associated with practices like horizontal and mud drilling as well as hydraulic fracturing
Flow testing has demonstrated up to one-third better flow than competitive standard port ball valves, while the series 727 weighs one-third less than equivalent flanged valves, easing handling and installation.Also on display was a full range of Victaulic grooved products for upstream, midstream and downstream applications, including the latest Victaulic Delta-Y Assembly, a combination of pre-assembled Victaulic cast grooved fittings, couplings and valves designed specifically for bulk cement/barite systems on offshore oil drilling platforms and mud drilling systems.
This new drilling program will incorporate 6,000m of aircore drilling, followed by a proposed 6,000m of rotary mud drilling, and is designed to define the host channel system and outline the extent of continuous uranium mineralisation.
Later, the TwinAir compressors will also be used for mud drilling and nitrogen purging applications, said Achamveetil.
Similar to mud drilling, this method uses air instead of mud and is advantageous when it is inconvenient to use water for drilling.
Mud drilling can fill cracks of deep geologic formations with the mud, causing a loss of pressure and a potential collapse of the hole.
