PRODUCED WATER TREATMENT FOR RE-INJECTION

Training Produced Water Treatment for Re-Injection – Produced water is the largest single fluid stream in exploration and production operations. It consists of formation water, or flood water previously injected in to the formation. Generally, produced water may be injected with minimal treatment. If the injected water contains solids large enough to plug the formation, injectivity will decline. Downhole solids contributing to plugging may include not only the solids escaping filtration, but solids generated after water treatment (eg corrosion, scale, and bacterial products). Consequently, stringent corrosion inhibition, scale inhibition and bacterial control, as well as filtration, may be required for matrix rate injection.

This course is designed as an effective practical shortcut to understand produced water chemistry, the main water contaminants, corrosion and bacterial problems, mineral scale formation, equipment and pipeline plugging, injection well and formation plugging, the method and operation of produced water treatment for reinjection, for either surface operation engineers or subsurface petroleum engineers, and anyone who involve in produced water handling, treatment, and related business activity.

The course content and approach are designed to suit participants of different background and different position in the company. It will be delivered as a to-the-point explanation by a professional instructor, utilizing an easy-to-understand examples and illustrations, especially the actual cases in Indonesia.

Tujuan Pelatihan Produced Water Treatment for Re-Injection :

By attending this course, participants are able to broaden or reshape their knowledge on the related subjects of his or her area of responsibility, learn more detail about many aspects of produced water handling and reinjection, know more how to treat the water and control corrosion, scaling, and bacterial action, understand how to select and use chemicals for treatment and operation of each equipment used for treatment, discuss and consult their specific problems they are about to bring to the class, and share experiences with others.

After completion of this course, participants will understand what produced water is and its fantastic devastating potential to surface facility, well, and formation, how to predict and monitor its characteristics, why and how to perform treatment before reinjection, and how to control and prevent these big and serious problems caused by produced water in the oil & gas field. Participants will know what the minimum requirements for produced water before reinjection and what to do to achieve that requirements.
