The operator’s goal
To assess reservoir quality and deliverability, an operator wanted to perform a campaign of appraisal well drillstem tests (DSTs). However, the necessary depth correlation before setting the packer is conventionally conducted with a wireline intervention run to acquire a correlation log. Switching conveyance systems adds time and cost to the DST for each well.
How Schlumberger provided wireless correlation
The operator liked using wireless telemetry to access downhole data in real time because that enabled adjusting the well test sequence as needed. The resulting improvement in test data reliability and accuracy informed better development decisions.
Schlumberger recommended wireless DSTs using Symphony testing, which incorporates the Position wireless correlation tool in the string to provide correlation data in real time without the need for a wireline intervention.
