COURSE OVERVIEW:

Well stimulation is a key set of technologies used to restore, enhance, and sustain well productivity and injectivity throughout the life of a field. It aims to remove near-wellbore damage, improve connectivity between the reservoir and the wellbore, and unlock bypassed or tight zones that are not effectively contributing to production. When properly designed and executed, stimulation treatments can significantly increase well deliverability, reduce drawdown, optimise artificial lift, and improve overall field economics.

This course provides a comprehensive and practical overview of well stimulation methods, with particular focus on matrix acidising, hydraulic fracturing, and acid fracturing in sandstone and carbonate reservoirs. It covers the full workflow from damage diagnosis and candidate selection, through treatment design and execution, to post-stimulation evaluation and optimisation. Participants will learn how to identify damage mechanisms, select appropriate stimulation techniques, choose and design fluids, and ensure that surface and downhole equipment, health, safety, and environmental constraints are properly managed.

The course emphasises the integration of geoscience, reservoir engineering, production engineering, and well services perspectives. Realistic examples and field case studies are used to illustrate common challenges such as skin damage, fines migration, scale, and water blocking, as well as the impact of geology, completion design, and operational practices on stimulation effectiveness. By combining clear theory with practical design rules and workflows, the course enables participants to support or lead stimulation projects with confidence.

COURSE OBJECTIVES:

After completion of the course, the participants will be able to:

• Explain the role of well stimulation in restoring and enhancing well productivity and injectivity.
• Describe the main types of well stimulation (matrix treatments, hydraulic fracturing, and acid fracturing) and where each is applicable.
• Identify common formation damage mechanisms and their impact on near-wellbore flow and skin.
• Screen and select candidate wells for stimulation using production, pressure, and completion data.
• Interpret basic rock and fluid properties relevant to stimulation design in sandstone and carbonate reservoirs.
• Select suitable stimulation fluids, additives, and diverters for different reservoir types and damage mechanisms.
• Understand the principles of matrix acidising design, including fluid systems, volumes, and pumping schedules.
• Understand the fundamentals of hydraulic fracturing design, including fracture geometry, proppant selection, and treatment parameters.
• Assess operational constraints and risks associated with stimulation, including pressure limitations, tubulars, and well integrity.
• Develop stimulation programs and job procedures that integrate subsurface, surface, and HSE requirements.
• Interpret post-stimulation well performance data to evaluate treatment effectiveness and calculate stimulation gain.
• Recognise common stimulation problems such as inadequate diversion, excessive leakoff, and premature screen-out, and propose mitigation measures.
• Collaborate effectively with service providers and multidisciplinary teams in planning and executing stimulation campaigns.
• Apply lessons learned from field examples to improve future stimulation designs and operational practices.

TARGET AUDIENCE:

• Production and reservoir engineers are involved in well performance and optimisation.
• Well stimulation, well services, and intervention engineers.
• Completion and workover engineers planning or supervising stimulation operations.
• Field and operations engineers and supervisors are responsible for implementing stimulation jobs.
• Geoscientists support stimulation candidate selection and fracture placement.
• Asset team leaders, technical authorities, and managers overseeing stimulation programs.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants who complete at least 80% of the total attendance time requirement.
