Technical Coaching

Technical Coaching is for anybody new to a welltest workspace: wellsite data acquisition, field-office data processing, or engineering data analysis.

Conventional training leaves responsibility chain management gaps. For example: reasons why we test, what happened before, what happens next, consequences and expectations.

Welltest iReports bridge those gaps with information on test operations, quality control, data collection, accurate validation, data processing, and regulatory compliance.

Technical Coaching bridges gaps between algorithms and reality, theoretical and practical. Data diagnostics start with raw wireline and production quality control and data validation, before moving on to PTA derivative tools. Finally, we have an exclusive module on careers in general.
