Common Question

What is the GCI when the wellbore has an open hole completion?

Archive Findings

The Directive 059 FAQ states that open-hole GCI is reported from the shoe of the last cemented casing to total depth.

That gives a practical rule for wells without perforations across a discrete cased-hole interval.

Questions@BenoitRegulatory.com

For open-hole completions, identify the last cemented casing shoe before calculating or reporting the GCI. Do not default to surface-to-TD or licence depth.

Current Guidance

Use current Directive 059 and Manual 027 for open-hole completion and GCI reporting.
