Add Value to Drilling Ops - How Do You Compare?

Technical Audits and Review

The purpose of the Technical Audit is to summarize historical area and regional data. The data is then analyzed; technical solutions are applied and benchmarked for efficient well construction operations.

The Technical Audit is the first step towards the recognition and identification of problems that need to be solved to enhance and accelerate the learning curve. It becomes the foundation of the forward technical limit plan, or Basis of Design.

The Technical Audit is an extensive review of area and regional well information. The audit begins by summarizing daily drilling reports and other pertinent documents from area and regional wells. The audits can also utilize global well data references by bringing experiences and best practices to bear in comparable wells, and environments.

The goal of the audit is to begin to breakdown time events of the drilling operations, and identify categories of time specifically related to Productive, Non-Productive and Invisible Lost Time. These categories can then be “benchmarked” both internally and externally and used to delineate areas requiring improvements.

Once appropriate well data is reviewed and summarized, the SEPI engineering team facilitator then works with the operator team to develop and analyze solutions.

SEPI has been successful in using the audit to suggest changes that operators have implemented. Some of these changes that have had dramatic results in drilling performance are:

• Recognition of tectonic stress requiring changes in casing seats previously not recognized.
• Changes in pore pressure trends as a result of tectonically induced stresses.
• Modification in execution events, such as tripping, controlling swab and surge pressures which negatively impacts Wellbore stability
• Risk identification, avoidance and management
