Oil and Gas Technical training > Micro Virtual Instructor Led Training – An analytical method to estimate maximum Recovery Factors for various displacement processes

About this Micro Virtual Instructor Led Training (VILT)

This 2 half day Micro VILT  teaches analytical methods to get a reasonable estimation of the maximum expected Ultimate Recovery by a viscous dominated displacement process like water, polymer or gas injection. Such estimation will allow the Reservoir Engineer to see the gap between the current booked ultimate recovery based on the current development plan. Based on this gap a further analysis of the sweep process in actual reservoirs can be done and further activities can be identified to manage their floods optimally.

The analytical estimation method is based on the interaction of micro and macro displacement efficiency. The micro displacement is based on an estimation using the Buckley Leverett approach and the macro displacement is derived using a Dykstra-Parson like approach, including estimates of non-flooded part of the reservoir by geological factors or well coverage aspects. The analytical estimation has its limitation like lack of the gravity or capillary effects. However, the gained understanding could lead to further insights and improve field activities. The method is applied in an Excel spreadsheet in combination with VBA, allowing for fast analysis and parameter sensitivity studies.

Participants will learn about the theoretical background in the morning session and in the afternoon, participants can apply this knowledge by using the Excel spreadsheet. The spreadsheet is available for use in the participant’s own company.

After the completion of this Micro VILT, participants will be able to:

  • Understand how to calculate micro and macro displacement efficiency of flooding techniques
  • Have used an Excel spreadsheet to do specific calculations
  • Use the analytical tool in their own companies

Breakdown of Modules:

Module 1: Basics micro-macro sweep

Module 2: Micro: Buckley Leverett analysis

Module 3: Macro: Streamlines

  1. Geology
  2. Well pattern – non-connected layers
  3. Developed area

Module 4: Channel Model

  1. Subdivide flow in individual channels and derive the micro sweep per channel, including the associated pressure drop.
  2. Incorporation of geological heterogeneities by assigning properties to a bundle of channels that represent the reservoir.
  3. Combining micro and macro sweep by tracking flux through each channels assuming the same pressure drop over each channel from injector to producer
  4. Deriving a plot of recovery versus injected volume.

Module 5: Usefulness for

  1. Waterflood in light oil
  2. Waterflood in heavy oil
  3. Polymer injection
  4. Gas injection

This Micro VILT is for Reservoir Engineers who are involved in waterflooding, including water based EOR, or gas flooding studies. It is assumed that the participants are aware of the Buckley Leverett analysis method.

Your expert course leader is a world leader in methods to enhance oil recovery and former Chief Scientist with Shell.

As Chief Scientist RE in Shell, he had been involved in many critical technology strategy decisions at the Executive Committee level, key technology projects and representation of Shell to the press.

His role as Global R&D Program Manager had brought him in contact with many key technology developments (chemical flooding, low salinity flooding, steam injection) and with research into novel recovery mechanisms (microbial EOR and nano technologies).

As Value Assurance team leader, he had traveled the world and had seen many of the key projects of Shell and reviewed the status of many projects, e.g. Kashagan Sour Gas Injection, Sakhalin Field development, Thermal injection in Qarn Alam, Upgrading for Colorado Oil Shales, waterflooding in Asab/Bab/Bu Hasa and many more. The key to many decisions lies in the understanding of the underlying displacement process, its vulnerability and opportunities for a set-up that allows further optimisation.

He played a key role in defining the Brent Field depressurization development that had very successfully maximised the recovery of gas and oil from the Brent Field.

Through his teaching to students and his mentorship of other staff at Shell, he knows how to engage and stimulate staff. In his current role as a consultant, he is involved with various companies like ADNOC, Maersk, Petrom, JAPEX, and PDO to analyse projects and future directions. From 2015 till early 2017, he was an Advisor RE in PDO, leading value assurance reviews and helping subsurface teams to identify new resources in existing fields. He was the editor of the 2011 Resource-to-Reserves publication of the IEA (International Energy Agency, Paris). For 10 years, he has been the Chairman of the EAGE European IOR symposium and sat on the program committees of the SPE IOR meeting in Tulsa and the SPE EOR symposium in Oman.

To further optimise your learning experience from our courses, we also offer individualized “One to One” coaching support for 2 hours post training. We can help improve your competence in your chosen area of interest, based on your learning needs and available hours. This is a great opportunity to improve your capability and confidence in a particular area of expertise. It will be delivered over a secure video conference call by one of our senior trainers. They will work with you to create a tailor-made coaching program that will help you achieve your goals faster.
