Paper Number: URTEC-3719030-MS
..., this is a hit and miss target. Since the flow rates are dynamic in any field, the facilities are frequently under or overdesigned, significantly impacting profitability. Continuous, prolonged production tests are essential to overcome the multiple challenges mentioned above, but the appropriate testing could...

E.g. for unconventionals, production may change so rapidly that intermittent well testing is insufficient and dedicated test separators are installed on each well...

Although pressure normalized flow rate is used to reduce the effect of variable pressure (Anderson et al, 2012), we believe that the effect of skin URTeC 5096 and variable pressure on observed decline...
