2. You are on the St. Malo {Gulf of Mexico} reservoir subsurface development team and you have just collected data from a new well. 'I'ou need to understand the relationship between acoustic impedance and porosity to improve your predictions of porosity from seismic. 'I'ou built a joint frequency table for porosity and acoustic impedance as follows: 1U 30 ED 7'0 913 Acoustic Impedance [Wst'i'S] c) Your subsurface team has determined the following thresholds and defined the associated events A and B as (2 marks): Event A: Porosity > 7.5% Event B: Acoustic Impedance
