Well performance is the discipline that aims to maximize a well production. It involves the understanding of the well production mechanisms known as the well inflow and the well outflow. The well inflow describes the laws that drive the flow of hydrocarbons from the reservoir to the bottom of the well. The well outflow describes the laws that drive the flow of hydrocarbons from the bottom of the well to the surface.
Both mechanisms are part of what is called the nodal analysis. Nodal analysis studies the evolution of the pressure between two system nodes. Applied to well production, the system usually starts with a node in the reservoir and finishes with a node in the surface tank or production separator. Fluid movement from one node to the other will trigger an evolution of the hydrostatic pressure and of the frictions (or pressure losses). The change of these two pressures (hydrostatic & frictions) will be equal to the difference in pressure between both system nodes. By measuring the pressure at a specific node (for instance, using a pressure gauge installed in the production separator) and using nodal analysis, the pressure in another node of the system can then be calculated and used to decide on specific action aiming at increasing the well production.
This course connects reservoir engineering to well performance and petroleum engineering. Participants will learn about reservoir and fluid properties and get a deep understanding of the inflow mechanism.
Taken together with Nodal Analysis – Well Outflow, it will teach what a senior petroleum engineer should know about nodal analysis, well performance, and well production.
Well production mechanisms are one of the most important things to understand when working at optimizing a well. Whether a well is in natural flow or if it uses artificial lift, mastering the concepts of inflow and outflow will allow us to understand any well behaviour and optimize it.
In this class, reservoir engineering, petroleum engineering and well performance will be put together to give a strong and global understanding of the inflow mechanism. Students will learn all the key concepts to master how hydrocarbons flow from the reservoir to the bottom of the well.
The course covers all aspects that govern the well productivity index. All parameters of the productivity index formula will be discussed. Their evolution with reservoir production and their impact on the well productivity will be explained.
To do that, the course begins by presenting different productivity index models and formulas. Then, characteristics of reservoir rock (porosity, saturation, permeability…) are presented to see how they impact the well productivity.
The next section of the training deals with PVT and fluid properties (solution GOR, bubble point pressure, viscosity…). Here again, the impact on the well productivity is reviewed.
The last part of the curriculum focuses on the other terms of the productivity index (like the drainage radius or the skin) and presents deliverability curves (aka IPR curves).
Practical topics are discussed along the course, like the risk of water or gas conning so that students can better react when confronted with these situations.
Combined with the course Nodal Analysis – Well Outflow, students should be able to apply this knowledge in practical situations, like determining if a well is a good candidate for a matrix stimulation or for a conversion from gas lift to ESP.

Certainly filled in some gaps in my knowledge
I enjoyed this module – I certainly learned a lot as the Inflow section to me is the most complicated. It certainly filled in some gaps in my knowledge.
A course that must take it
In this course you will learn and undestand the parameters that have impact in productivity index. Also you learn basic reservoir parameters and their explanaition and relationshiop between them. For sure is a course that must take it.
Explanations very clear and straight to the point
I followed the well inflow course when beginning a career transition from geology to reservoir engineering. I found the explanations very clear and straight to the point with exercises well elaborated to reinforce the concepts and cover all the doubts. It is definitely a very good starting point for those willing to go deeper into production engineering. Strongly recommended.
Interesting course
Interesting course to better understand reservoirs in oil and gas. I took this course and it was awesome in giving me a better understanding of wells in oil and gas production.
Very good content, very clear explanations
I have taken this course as I was looking for a cost effective training alternative for field production engineers in Western Africa, during the 2015 downturn when all budgets had to be drastically reduced. This course proved to be very interesting solution. Very good content, very clear explanations. The feedback received by the field engineers team was excellent. The knowledge of wells mechanisms improved and it was noticed in the operations. I feel I have fully achieved my objectives with this training. I recommend this course if you are looking for a solution to train your operational staff with some years of field experience at a very competitive cost.
One of the best courses I have taken
One of the best courses I have taken in well inflow and outflow. I recommend it to anyone looking to improve their understanding of this subject. Thank you Damien!!
Easy to follow
Great course that I actually followed via the bundle which allows for an integrated course. That part covers the downhole reservoir interface and flow aspects from the basics. You will get the most of it if you write down notes as a school lessons and make the effort to solve yourselves the examples. It is pretty easy to follow as the instructor points the reasonning path on pictures. Provided that, you will get a good introduction and understanding to the progress by yourself in a working environment on RWI modelizations and parameters.
Especially ternary diagram and relation between kh/kv ratio relationship with risk of water coning
Great to refresh theoretical knowledge regarding characteristics of reservoir rock, mainly relative permeability part.
Good, short slides with enough info
Slide information is limited, but very informative for refreshment before the start of the Gas Lift part.
I really liked all the details on the well inflow section
Great course to take. Very useful and detailed, I learned a lot!!
Clear content delivery making the technical content easy to understand
Great presentation focusing on the key concepts of each component. I really appreciate how the presentation is brief for each topic. The explanations for each technical section are brief but easy to understand.
Feedback on Course depth
I expected the course to include more advanced , high level mathematical calculation exercises .
Nodal analysis review
With this course, I gained a solid understanding of nodal analysis and was able to revisit many concepts learned during university. The course is comprehensive and well suited for professionals working in well production
A refreshing take on Nodal Analysis
initially, I wasn’t very motivated to go through another nodal analysis topic since I’ve covered it so many times before. However, I’m really glad I decided to do it this time. the way you explained several of the concepts was unique and not something I had heard before – clear, insightful and refreshing. I especially appreciated how you consistently connected the theory to real well observations that engineers encounter in the field. The practical perspective made a big difference.
Parmeability effect on well production
Well saturation (water and Gaz) has a big impact on the well PI.
Well saturation increase (water and gas) will be visible at surface as BSW and GOR increases. These increasing will cause well production decrease.
Highly recommended
I would highly recommend this course to anyone working with wells whether their focus is on surface or downhole. Damien has done an excellent job combining theory with practice, clearly explaining the real life applications in a simple and practical way!
Recommended Courses with pragmatical explanation
Nailed it! I highly recommend these courses for professionals in oil and gas production and well performance. I appreciate the simplifying explanation markups during courses, that makes understanding easier. We need more related realistic case (even with sketch) examples to emphasize our understanding.
Simple to understand
Good explanation for anyone
nodal analysis course

Well inflow
Good refresh. First time I come across the triangle for Saturation
