They'll get a better idea of the reservoir's deliverability of any moveable HC's post-testing as in how many BOPD flowed. Next update should b about reaching casing point, running casing string, waiting on cement & then preparing to pressure test the BOP.

For now Logging while drilling tool that sits just behind the drillbit should start to relay any inherent change in the drill mud's property if light oil is present in the formation at their prognosed depths. This should b verified by oil shows from the cuttings & increase in gas readings of C1 to C5 on the gas chromatograph. This basically tells u that HC's r present. What one needs here is commercial & movable quantity of HC's which is confirmed from the WL logs & fluid sampling. Hope this helps.
