Here it is, they could not get a sample aka it would not flow into the WFT. So now they will try a cased hole test to try to get a sample out aka, get it to flow.
And also, as they do not have a sample as yet, this could be 80% water, or 50% water or 100% oil - nobody knows until they get a sample -

............Attempts to sample formation fluids using a wireline formation
tester were not successful and thus the zone will require cased hole testing to
confirm whether they are oil bearing.......................
