... flowlines to a new platform. In order to manage corrosion, the project corrosion monitoring objective was to flag any short fall in corrosion inhibitor injection rates to minimise internal corrosion in the ten subsea infield flowlines and to confirm the corrosion inhibitor is working. The timeline...

... on the environment. Multiple challenges faced in selecting the optimum material for flowlines are shown in Figure 1 . FLOWLINE EXPERIENCES Abstract Oil & Gas flowlines are paramount for safe and reliable production of hydrocarbons, ensuring their integrity is one of the key tasks for all operators. Petroleum...

... internal field-jointing solution at a low marginal cost for flowlines and risers fitted with a plastic liner. To achieve this target, the following constraints and function were identified: The main function of the FBJ is to feature excellent sealing properties at weld locations to guarantee...

...Ultrasonic thickness (UT) measurements have been carried out after every acid cleaning jobs for the well flowlines to ensure the integrity with respect to the required thickness as per design. Profile Radiography ⁵ has been carried out for assessing the extent of the scaling inside...

... detected on the bioprobes are representative of the extent of fouling in the flowlines. Corrosion Monitoring The results from the various corrosion coupons indicate that, in general, corrosion rates on NSP, WSP and SSP are low (<1 mpy). In the Header, however, corrosion rates are mainly in the Moderate...

...Thermal insulation is normally required for subsea flowlines as a part of the flow assurance strategy. The insulation shall give the necessary cool down time to allow for measures to be taken to avoid wax or hydrate formation. The overall design parameters of the Kristin flowlines are found...

... rates of carbon steel flowlines and tubing in the presence of carbon dioxide. The model can be applied also for processing facility piping and equipment. The influences of dissolved corrosion products, hydrogen sulfide, crude oil type, acetic acid and flow regime on the corrosion rate are predicted...

...Carbon dioxide hydrogen sulfide carbon steel well tubing flowlines steamflood localized corrosion temperature INTRODUCTION This is a case study of an unusual example of severe corrosion in producing wells of a steam drive. Expansion production wells in a high pressure steam drive...
