A squeeze succeeds when cement dehydrates against a permeable face and builds a filter cake that seals. That requires a path to the problem area, an injection point, and filtration into the formation or the channel. Squeezing against an impermeable zone just pressures up the wellbore and achieves nothing, which is why injectivity testing before the job matters so much.

Pressure response during the job tells the engineer what is happening. A gradual pressure climb with declining rate shows cake building and dehydration; a sudden pressure rise shows blockage at the perforations; no pressure rise at all shows the cement going somewhere unintended. Reading that response and deciding whether to continue, hesitate or stop is the core operational skill.

Many squeezes fail because the diagnosis was wrong. Sustained casing pressure from a tubing leak will not be cured by squeezing the casing shoe; communication behind a liner may not be reachable through the perforations chosen; a micro-annulus seen on a bond log may not be a flow path at all. Diagnosis before design is where this course starts.

By the end of this training, participants will be able to:

• Diagnose isolation failures and locate the flow path.
• Interpret logs, pressure tests and production evidence for remedial planning.
• Explain squeeze mechanics, dehydration and filter cake build-up.
• Design high pressure and low pressure squeeze treatments.
• Select hesitation, running or walking squeeze procedures.
• Design slurries for squeeze applications.
• Select tools and placement methods, including retainers, packers and bradenhead squeezes.
• Plan perforating and injectivity testing before the job.
• Execute and interpret squeeze operations from pressure response.
• Evaluate results and select alternative remedial methods where squeezing is unsuitable.

The course is instructor-led and case-based. Participants diagnose isolation problems from logs, pressure data and well histories, design squeeze treatments and interpret execution pressure records. Both successful and failed squeezes are examined, with the reasons. Participants are encouraged to bring their own remedial problems for discussion.

Organisations sending participants to this training will:

• Diagnose isolation problems correctly before spending on remedial work.
• Improve squeeze success rates and reduce repeat jobs.
• Reduce rig time spent on unsuccessful remedial cementing.
• Resolve sustained casing pressure and integrity anomalies.
• Support abandonment requirements with effective isolation repairs.

Participants will:

• Be able to diagnose where and why isolation has failed.
• Understand squeeze mechanics and design.
• Be able to select tools, slurries and placement methods.
• Be able to interpret squeeze pressure response in real time.
• Know when alternative methods are a better choice.

• Drilling and well engineers
• Well intervention and workover engineers
• Well integrity engineers
• Completion engineers
• Cementing service company engineers
• Rig site supervisors

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
