This workshop will explore field experiences related to corrosion issues on deepwater production platforms. With a design life of typically 20 to 30 plus years, a deepwater production solution must be ‘fit for purpose’ and adaptable enough to accommodate an evolving production stream over the life cycle. This solution may be described as ‘management of change’ (MOC), that if not properly addressed can lead to further problems and costly failures.
Materials of containment, cathodic protection (CP), coatings and inhibitors are critical areas pertinent to deepwater mechanical integrity. Coatings can be external for sea water, marine atmospheric, or internal for production fluids side. Inhibitor selection can be a challenge and chemicals are usually tailored to the composition of the well flow. As the hydrocarbon flow evolves over the productive life of the field, the original materials selected and coatings design may prove less effective. Likewise, the inhibitor needs may change, such as the use of an alternative inhibitor formulation, or increase in dose or concentration. These changes could impact environmental constraints and actual volumes required, and therefore impact costs and revenues.
If enhanced recovery taps deeper reserves, or the platform becomes a host for nearby subsea fields, the topsides equipment may be dramatically affected. Hence material changes may be needed to maintain production and mechanical integrity.
With the high cost of production shut-in, and deepwater remediation, it pays to address these issues at the design phase or as a capital expenditure (CapEx), rather than the operating expense (OpEx) phase. During the OpEx phase, changes are far more expensive, and invariably produce further performance risk or safety issues to the asset, environment, and people involved.
The goal of this workshop is to bring together materials, corrosion, and facilities engineers along with mechanical designers to promote a robust fit for purpose solutions. Interacting through case study presentations, these groups will better understand the drivers and limitations they each face. Ideally, if all parties are involved at the CapEx stage of facilities design, the results will be more adaptable to accommodate changes throughout the life of the field. In this way lessons learned, and most importantly shared and implemented, will greatly benefit the industry.
Workshops maximize the exchange of ideas among attendees and presenters through brief technical presentations followed by extended Q&A periods. Focused topics attract an informed audience eager to discuss issues critical to advancing both technology and best practices.
Many of the presentations are in the form of case studies, highlighting engineering achievements and lessons learned. In order to stimulate frank discussion, no proceedings are published and members of the press are not invited to attend.
Proceedings from the workshop will not be published; therefore, formal papers and handouts are not requested of speakers or panel members. A URL containing released copies of the workshop presentations will be available to attendees following the workshop.
In remaining consistent with workshop objectives and SPE guidelines, commercialism in presentations will not be permitted. Company logos should be used only to indicate the affiliation of the presenter(s).
Attendees will receive 1.6 CEUs.
One CEU equals 10 contact hours of participation. CEUs will be awarded through SPE Professional Development for participation and completion of SPE workshop. A permanent record of a participant’s involvement and awarding of CEUs will be maintained by SPE.
