Addressing Wellbore Integrity in Practice

Safety is our top priority. We maintain highstandards of asset integrity and process safetyand take a systematic approach to wellsmanagement.

At Shell, we have a systematic approach to managing wells.For each phase of a wells lifecycle from well design,through well construction, production and abandonment our operations are subject to detailed technical standards,processes, audits and reviews.

We have a standard in place that sets a common approach toour global wells activities. The Shell Wells Standard defines

Asset integrity is critical i n well management.An integrated approach to well design, technicaland operating integrity is required for all activitiesthroughout the lifecycle of a well.

HSSE (health, safety, security, environment) requirements andtechnical requirements covering the lifecycle of a well. It alsosets out requirements for assurance and competency for wellengineering and completion, and well intervention disciplines.Our standard is mandatory and applies to all Shell companies,contractors and joint ventures under our operational control.

Our systematic approach also covers the prevention andmanagement of well control incidents and our emergencyresponse to these incidents.

MANAGING WELLS

INTEGRATED WELLBOREINTEGRITY MANAGEMENT

The competence of our people is an underlying factor andprerequisite for integrity throughout all phases of a well.We have competent people who design the well and conductindependent sign off for its design. To help ensure this, wedevelop the competencies of our staff through a comprehensivelearning programme.

We design our wells according to definedcompany standards and supporting manualsto ensure integrity right from the beginning.These include:

n Design manuals and standards: Our engineering designsare developed in line with our standards and comply with orexceed industry standards.

n Material procurement specifications:Our well materials aresupplied to defined specifications and in accordance withwells technical standards.

n Design assurance: Regional discipline leaders in Shellundertake the technical assurance to validate and endorse

well design. This is based on our global well deliveryprocess, and according to our Discipline Controls andAssurance Framework (DCAF).

n Risk register and mitigations:Identified risks are captured ina wells risk register to ensure concept and design risks havebeen identified and mitigated.

n Design parameters:All safety critical elements, performancestandards and design parameters are i dentified by a Shellwell design engineer who provides a well specification andclear operating and integrity parameters for the constructionand operation phases of the well lifecycle.

We manage technical and construction risks duringwell construction, operation and maintenance,through to abandonment. Again, we apply globalmandatory standards and manuals to this elementof well management. At all times, well control ismaintained by at least two independently testedbarriers.

We construct our wells in accordance with our global standardsand in compliance with the Shell Well Technical Specification.

During construction, the Shell well delivery leader undertakes thetechnical assurance of the well construction activity as defined in

Our global well integrity management systemensures that the strategic imperative safetytakes priority is consistently applied inmanaging well integrity across Shell.

To support the operation and maintenance components of wellintegrity we have a Well Integrity Management Manual(WIMM) and an electronic application software tool (eWIMs).These tools are key to ensuring wellbore integrity in Shell andare globally deployed.

our global well delivery process and according to our DisciplineControls and Assurance Framework (DCAF) to assure the well isconstructed in accordance with the design requirements asdetailed in the Shell Well Technical Specification

We ensure our staff who construct the well and manage the riskhave the right competencies.

When the well is handed over to the operations team it ismandatory to validate that the well has been constructed andtested in accordance with the Shell Well Technical Specification.

The software package eWIMs draws information from our wellmaintenance and well monitoring systems and compares thedata against a defined set of rules contained within the wellfailure model. Maintaining well integrity is ensured by requiringtimely action is taken whenever any deviation from the rulesis observed.

Developing our people is key to achieving oursafety and business performance aspirations.

Shell provides a post graduate development programme forits well engineers, and completion and well interventionengineers. It is the foundation for wells staff development.

The programme normally takes three and a half years andcombines classroom study, self study and on the job training,culminating in two examinations. It can also lead to entryinto Master of Science degrees in Well Engineering, WellCompletion, or Well Intervention Engineering.
