As part of the development of Vaca Muerta Fm. in Neuquén Basin Bandurria Centro field, surface microseismic was acquired during hydraulic stimulation in a 1500 m drain horizontal well.The company has been using sliding sleeves frac ports to complete horizontal wells, activated by both ball mechanism and/or coiled tubing (CT). In most of the wells both systems are employed, which mean a challenge to calibrate any microevents data set. Due to this a feasibility study was made before the microseismic acquisition, in order to test several surface and well monitoring designs.From feasibility study results a mixed design was implemented in surface, consisting of two asymmetric arranges: a star and a set of patches, both equivalent and complementary.In this job some raw records and processed data are presented. Also, examples of registered CT activated sliding sleeves microevents and some differences between the star design and the patches design found during the field implementation and later processing will be included.
