MagTrak located gas/oil zones and saved operator two days and $200,000
An offshore operator in China’s Bohai Bay needed to identify the productive gas/ oil zones in a new well block. Traditional methods used for gas/oil identification use radioactive or chemical sources to acquire porosity measurements. Because these sources are very restricted in Bohai Bay, the company wanted to find a way to acquire porosity measurements in their 12-¼-in. borehole using another option.
Baker Hughes, a GE company (BHGE), proposed use of its MagTrak™ loggingwhile- drilling (LWD) magnetic resonance service to gather the measurements and identify the potential gas/oil zones. MagTrak’s real-time nuclear magnetic resonance transversal relaxation (NMR T2) accurately measures formation porosity using no radioactive or chemical materials.
The operator was very interested in testing out this new technology as a potential way to comply with the Bohai Bay restrictions while developing the rest of the block.
