Critical View of Operations

• Identify Missed Opportunities

• NPT - Tool not a Stick

• Use data to focus efforts

Capitalize on Commonality

Use measurable and meaningful KPI’s (SPM)

Work together as a team (office, field, service co.,

networks)

Celebrate Success – (e-mails, competition, awards, etc.)

Manage Operations for Performance

Drilling Wells is a process and the effectiveness of process controls

determines the end result

We treat drilling wells as a repeatable process that can be optimized

Controls are used within our process to ensure adherence to soundengineering standards and effective management of risks

– Controls and Processes are in place for:

• Reservoir and geological planning

• Drilling planning and design

• Field implementation

Continuous improvement of process & controls to maximize efficiency

is everyone's responsibility

Engineers are assigned to individual technologies and drilling

projects and are held accountable to deliver positive results

Individuals are assigned to manage specific technologicalcomponents of the process and the contracts associated with that

technology Drlg Eng teams are assigned to specific asset teams to focus on that

team’s drilling projects

Some individuals also have longer term strategic initiatives requiring

both technical and management skills Ops team concentrate on execution safely and efficiently

Work Processes to manage high activity

6 drilling teams focused on specific areas

– Drilling Operations

– Drilling Engineering

• Performance

• Measurements

• Tangibles

• Fluids and Environmental

• Projects

Rigorous contract management

Cross funct ional integrated CPDEP process for

– Business Planning,

– Facilities,

– Well planning and execution

Data collection through “ WellView”

– detailed performance tracking and analysis

– trends and changes can be seen and addressed

Special local technology and techniques have been developed

Success = f (clarity of the vision + ability to change+ tolerance for pain)

“In order to succeed we must accept failure.”
