A robust well integrity process covers the entire life cycle of the well beginning with well design and carrying through abandonment. Depending on the hydrocarbon composition, well complexity, regulatory oversight, and company approach, there is considerable variance around the globe on how this has been deployed. Wild Well offers well integrity solutions that meet operators’ specific needs. We will tailor our well integrity offering to meet the specific needs and unique aspects of the targeted area of operations. Identifying well integrity issues often requires close examination. As wells age, issues can become more pronounced due to lack of maintenance, poor zonal isolation, corrosion, erosion, etc. These can lead to wells being shut in or, in extreme cases, hydrocarbon releases requiring emergency intervention.
Implementation of a successful well integrity program will have significant positive impacts for any organization. These include:
Improved HSE
Protection of assets reputation and rights to operate
Extended well life and increased production
Reduced workover and intervention costs
Improved well documentation
Improved cross-organizational communication
Enhanced engineering productivity
WELL INTEGRITY GAP ASSESSMENT
The well integrity gap assessment is the initial step to clearly understand the current implementation level. It will help the company develop a way forward that prioritizes critical items. The specific scope of work will be tailored to meet the client’s requirement for the field and can be delivered in phases to meet budgetary concerns. With the closure of each gap, there will be a positive impact on the organization. Ultimately, this activity will provide clarity of the well integrity status for the producing and shut-in well stock. This will lead to more efficient operations that include enhanced safety and reduced operational and environmental risks.
The process will review the existing Well Integrity Management System or other systems in place and provide a gap analysis with recommendations to address the specific items. The focus areas will include, but will not be limited to:
Current System: The level of well integrity implementation may range from non-existent to cursory to industry leader. Regardless of the implementation level, a third-party review will reveal gaps and opportunities to enhance the process.
Well Stock: It is imperative to review the entire well stock in the field and develop a holistic overview. Some of the wells, including already abandoned wells, can pose risks that are not visible under normal scrutiny.
Total wells in field
Abandoned wells
Shut-in wells
Injection wells
Disposal wells
Producing wells (naturally flowing, sucker rod pumps, electric submersible pumps, gas lift)
New Well Design: Because well integrity is a life-of-well responsibility, it should be addressed in a well or field’s basis of design. Some of the specific topics are:
Metallurgy suitability for initial wellbore fluids
Metallurgy suitability over the life of the field, particularly with increase of water or H2S
Barrier envelope
Zonal isolation
Abandonment criteria
Well Records: Each well will have significant documentation tied to it:
As-installed wellbore, wellhead and tree schematics
Well handover documentation
Cased and production logs
Sustained casing pressure database
Abandoned well schematics
Interventions documentation
Centralized well file systems
Surveillance: Over the life of the well, the production/surveillance teams will conduct periodic assessments on well stock. This will vary from field to field and company
to company. These activities may include:
Wellhead and tree inspections
Production logs
Corrosion logs
Casing thickness logs
Annulus mechanical integrity evaluations
Compliance: The process will identify areas where a gap may exist to adherence to applicable policies, procedures, and regulations. Some of the areas of investigation include company well integrity systems (barrier policies, zonal isolation, breaking containment policies) and regulatory (well policies, reporting requirements, well diagnostics to satisfy regulatory needs).
