This course about 4D Time-Lapse seismic aims to make Subsurface Practitioners and Managers familiar with this technology so they can confidently initiate projects themselves, interpret the data, integrate the insights and extract its value.
The course presents the basic concepts and applications of 4D Time-Lapse seismic. After this Course, those with seismic interpretation experience should be comfortable enough to perform their own initial 4D interpretation in relatively basic settings, while others should be comfortable to make the best use of 4D seismic results. It should also enable Subsurface teams considering acquisition of this data to assess the business case and expected value.
To these aims, the course will illustrate both the benefits and pitfalls of this fascinating technology.
Who should attend
Due to integrated nature of 4D seismic, the Course should appeal to all subsurface disciplines, well engineers, and team leaders. Students are welcome too.
This Course aims to appeal to subsurface staff currently active in field development and reservoir management. For those interested in CCS, this Course will also be useful given its focus on monitoring of subsurface dynamic effects, and the description of technologies enabling innovative and low-cost monitoring.
Course content
To achieve the Learning objectives, the Course equips the participants to tackle a number of technical and non-technical hurdles. These include (but are not limited to):
- Estimating 4D seismic signal types and magnitudes
- Understanding noise types and how to suppress these through choices in Acquisition and Processing
- Extracting the various types of 4D attributes, understanding their benefits and limitations
- Integrating the results and calibrating reservoir models into one or more 4D-consistent dynamic subsurface scenarios including uncertainties
- Communicating results clearly and concisely as input for decision-making
- Describing ongoing and expected technology developments and how these can better solve existing challenges
We also include a diverse set of case studies showing examples of business impact that 4D seismic had in various settings.
Learning, methods and tools
The course contains a mix of presentations, hands-on exercises, Learner Report-outs, and a Team Assignment. Case studies are discussed to “see 4D in action”. The exercises are table-top. Short exercises throughout the Course aim to help Participants internalise the various basic technical and theoretical concepts. The final exercises are done as Team assignments, working on actual real-world 4D interpretation problems.
Report-out and discussion is a key learning tool.
