DESIGNED FOR YOU, IF YOU ARE...

Completion, well servicing or workover engineers and supervisors, with client or service
companies, familiar with well control operations.

 

HOW WE BUILD YOUR CONFIDENCE

We will use slides presentation, paper exercises and examples from real cases.

Group discussion and experience exchange.

​

THE BENEFITS FROM ATTENDING

The organization will gain, in sending their employees to attend this training course, the following:

• Reduction in the cost of the well by proper selection of well servicing and workover operation

• Extending the well life and control it, achieve the optimum production using well servicing and workover operation.

• Ensuring the well integrity and avoiding all risks during well serving and workover operations.

 

By the end of the course, you will feel confident in your understanding:

• Select the right means for well service,

• Design well servicing or workover programs,

• Supervise well servicing or workover operations.

DAILY AGENDA

​

Day 1

TYPES & MEANS OF INTERVENTION ON PRODUCING WELLS

Main types of intervention: measurement, maintenance, workover.

Introduction to main means (wireline unit, coiled tubing unit, snubbing unit, workover rig): principles, area of application.

 

Day 2

GENERAL PROCEDURE OF A WORKOVER

Main operation steps: chronology, more tricky operations from a safety point of view, main operations.

Case of depleted reservoirs: losses and formation damage, kick-off after the workover.

 

Day 3

WELL KILLING PROCEDURE FOR A PRODUCING WELL

• Killing the well by circulation: area of application, basis procedures (direct or reverse circulation), elaboration of the forward-looking pumping diagram.

• Killing by squeeze: area of application, basis procedure, elaboration of the operating program, case where the injectivity test is unsatisfactory, squeeze and bleed-off method.

• Final killing phase: observing the well, operations to run after packer “unsetting”.

​

Day 4

WELL OPERATIONS ON PRODUCING WELLS

• Wireline operations: principle and area of application, surface equipment, wireline tool string, WL tools, fishing tools, safety during operations.

• Coiled tubing operations: principle and area of application, surface equipment, CT downhole equipment, CT safety and operating considerations
