Wellbore Treatment Training Course

Wellbore treatment refers to the use of specific techniques and procedures in oil and gas wells to tackle different issues that can affect the performance of the well. These treatments are applied to the wellbore, which is the drilled hole used to extract hydrocarbon reserves from the ground.

PetroSync understands that an engineer must possess a high level of expertise in wellbore treatment knowledge to effectively recognize and assess challenges such as formation damage, skin damage, scale buildup, and other operational obstacles. This proficiency enables the involved engineer to devise and implement appropriate treatment strategies to mitigate these issues and enhance the overall performance of the well.

By having a deep understanding of wellbore treatment, petroleum engineers are equipped to make well-informed decisions, optimize production, and maximize the extraction of hydrocarbon resources from the well.

What Is a Wellbore Treatment Training Course Overview?

The Wellbore Treatment training course aims to improve participants’ understanding, knowledge, and decision-making skills regarding wellbore treatments for enhancing well performance. To ensure effective decision-making, a solid understanding of different formations and basic reservoir properties is essential.

Hence, the training course will initially focus on comprehending the geological and reservoir properties of vertical, horizontal, and multilateral wells. It will then cover fundamental concepts related to formation damage, acidizing, and hydraulic fracturing.

Additionally, the training course covers important areas such as quality control during acidizing and fracturing, the implementation of treatments, and the continuous monitoring of pressures and other crucial parameters throughout and after the treatments.

A vital aspect of the training course entails participants working together in teams to assess and create stimulation treatments. This collaborative approach facilitates the examination of key information and parameters discussed throughout the training course.
