Leak detection in high-debris well in the US

We acquired US-based well integrity specialist, Proactive Diagnostic
Services, Inc. (PDS) at the end of 2018. We’re excited to share some of their
recent success stories – here is the first, and watch this space for more going

In October 2018, a US operator was experiencing higher-than-usual water
production in one of its wells. It needed to determine the cause, quickly, and
called on PDS to deliver the solution. Read the full story

Thanks to PDS’ 24 years of well logging expertise and diagnostics
excellence, they were able to successfully identify a leak in the casing liner
and pinpoint its precise location, enabling the customer to take appropriate
remedial action.

PDS ran a 24-arm caliper on slickline in memory mode, however were
faced with extremely challenging downhole conditions and a significant level of
well debris. So, to eliminate any potential loss of caliper recordings, their experienced
field engineers performed a second caliper run to ensure high quality data
acquisition. PDS then ran a PLT – and this powerful combination of caliper and
spinner temperature pressure gave the customer the accurate and insightful answers
it needed to make truly informed decisions about its well.

PDS has been servicing Alaska, the Lower 48 and Gulf of Mexico regions
for many years. With the PDS business now part of READ, we are better placed
than ever before to support oil and gas operators around the world with production
logging, well integrity and reservoir evaluation services, and unrivalled data analysis
and interpretation.
