1. SRO can be run on e-line only during builp-up Rum SRO with EMR as back-up SRO Issues – cost, time to run e-line, specialist personnel, leak tendency from lubricator for HPHT wells. Witness gauge calibration if possible Sampling – Oil down hole if FBHP > Pb Gas – all surface samples 3 surface samples after main flow period Two types of dh sampler Single phase sampler – nitrogen compensated – laser DST string sampler – no compensation for pressure drop- dst company Positive displacement sample – recommended – laser Underbalance fluid should be selected to prevent hydrate formation May also kick-off well by injecting methanol Salinity checks during clean-up to confirm when well is clean
