WHO SHOULD ATTEND: Engineers and geoscientists with a BS degree and with 2 or more years’ experience in managing and/or developing mature oil fields. Students should have basic proficiency in Excel and bring their own laptop.
COURSE DESCRIPTION: Developing and managing mature oil fields can have many challenges. Ideally, a history-matched reservoir simulation model using a comprehensive reservoir model will guide choices, such as well locations and water injection rates. Many fields, however, lack such tools and need simpler, less sophisticated methods to improve results. This is where the capacitance-resistance model (CRM) can help.
The CRM evaluates injector-producer connectivity using injector and producer flow rates and bottom hole pressures (if available). It is a simplified model capturing the effects of injection on production and does not require any geological model to operate. Results can be used to adjust injection rates, identify fluid escape, and compare with geological information. CRM results can also help reservoir simulation model development.
This course provides prospective users with the knowledge to use the CRM and apply its results to manage mature fields. Through numerous field examples, we show how the CRM can be applied and the results interpreted. Both engineers and geoscientists will see how the results can help their challenges.

SAMPLE TOPIC FROM THE CLASS:
“Small Data + Simple Model = BIG DATA”
REGISTRATION should be made at least one month before the start of a course. It is recommended that participants register early due to limited seating. However, we will accept paid registrations up to the last business day before the class, provided there are seats available. Registrants will receive a confirmation email within 48 hours of registration and will receive complete venue information two weeks prior to the first day of class.
As a reminder: your seat in a course is not confirmed until payment is received.
