BSEE's New Approach to Inspections

As a part of their regulatory remit, BSEE is undertaking inspections to ensure the integrity of the structures and processing equipment on the OCS are properly maintained to continue safe operations with no harm to the environment. As a part of this undertaking both scheduled annual inspections, and periodic and unannounced inspections are performed.

Choosing & Using Condition Monitoring Locations (CMLs)

A facility that processes hydrocarbons needs an inspection program not only to meet regulatory requirements, but also to protect its bottom line by actively managing risk. While this goal may be a foregone conclusion, its achievement is not.  So, what goes into a well-designed inspection program? And what does it produce? How can the most value be derived from inspection dollars?

Reservoir Souring Prediction

There are many production reservoirs that produce high levels of hydrogen sulfide (H2S). Some of these fields know before initial production that there will be high levels of H2S and thus are able to design and manage accordingly; however, some fields will begin producing an increasing amount of H2S following water injection. These fields are more difficult to manage and require a means of prediction to help make cost-effective project decisions. At GATE Energy, we have the technical knowledge and experience to apply our own approach to souring prediction which can enable design and operational decisions to be made to mitigate the risks associated with such H2S production.

Fit-For-Purpose Integrity Management of Seawater Injection Systems

There are many projects that leverage water injection or waterflood (WF) as a secondary recovery tool to increase oil production returns. Many of these projects’ economic viability is intrinsically linked to the ability to inject large volumes of water into the reservoir as a means of oil drive and pressure maintenance. For these fields, it is vital that the integrity of the water injection system is maintained through fit-for-purpose material selection and asset integrity management processes.

INTEGRITY MANAGEMENT PLAN PITFALLS & BEST PRACTICES

ntegrity Management (IM) planning is a challenge that is currently center-stage with oil and gas operators as the downturn has led to focused attention on extending the life of existing assets while optimizing ongoing operating expenditure. This is particularly true in the deepwater basins of the world, where capital costs are high, the cycle time to deliver new facilities is long, and the life extension of existing assets to support hub and spoke tieback developments is often commercially favorable.

FAILURES RELATED TO API 5CT HIGH STRENGTH STEELS

American Petroleum Institute (API) 5CT high strength steels are extensively used for casing strings inwells subjected to high cyclic hydraulic fracturing loads. While non-sour grades of API steel such as P110 casing strings have been used satisfactorily for well construction, standard API P110 connections have seen higher rates of failures than pipe body failures in shale wells that require hydraulic fracturing.

NACE 11099: Further Analysis On M13Cr-110 Nace Tm0177 Method A Test Acceptability Prediction

Martensitic stainless steels continue to be one of the most widely used corrosion resistant alloys in oil and gas developments. Determining if a martensitic stainless steel is acceptable in an unproven environment requires testing to confirm, but predicting the outcome of a given test environment is often initially based on personal experience rather than a qualitative and quantitative assessment.
