June 2017 Meeting – Annual General Meeting, and Operational Geomechanics
June 1 @ 3:30 pm - 7:00 pm CESTFree
The next meeting of the Dutch Petrophysical Society will be at the Kivi building in Den Haag on Thursday 1st June 2017.
The theme of the meeting will be
“Annual General Meeting”, and “Operational Geomechanics”
Before the technical talks, we will conduct the annual general meeting of the DPS where the year will be reviewed, the financial position of the society presented, and the outgoing board will hand over to the newly elected incoming board.
Following the AGM we will present two talks:
Operational geomechanics: an interdisciplinary topic
Peter Schutjens (Shell)
Operational geomechanics is a relatively young discipline (a few decades old) that is now actively studied and applied by hundreds of professionals in industry, academia and service companies. It is built on foundations of civil engineering, rock mechanics and soil mechanics, and is characterized by an interdisciplinary approach. I will describe the operational issues that shape the job profile of an operational geomechanicist, which include Earth stress state analysis, pore pressure prediction, borehole stability, reservoir compaction and deformation, subsidence, casing deformation, induced seismicity, sand production, and reservoir and overburden monitoring. Next to making sure that drilling and production operations are efficient and cost-effective, there are important safety aspects to the job of a geomechanicist. I will describe a few, also outlining the computer tools that we use to tackle these focusing on the importance of good-quality field data, fit-for-purpose modeling and closing-the-loop between model results and operational decisions.
Structural geologist by training, developed in geophysics and materials science, with specialty experimental rock mechanics. First on salt powders (at Utrecht University, the Netherlands) and from 1989 till 1999 in Shell Rijswijk on reservoir rocks. Work involved construction of deformation apparatuses, core data collection, microstructure analysis.
In 2000, one year as an exchange scientist at SINTEF in Trondheim, Norway, mainly on 4D-seismic and AvO-analysis. Moved to Shell in New Orleans in 2001, starting 10 years of operational support on geomechanics, petrophysics and geophysics (the 3Gs) in Gulf of Mexico and North Sea (from Aberdeen). From 2010 to 2014, team lead geomechanics and pore pressure prediction in the new Shell Technology Center in Bangalore, India, and global discipline lead for geomechanics. Since Jan. 2015, back in Shell Rijswijk for project work on the interface of the 3Gs to support assets with geomechanics technology
Transformation in minimizing operational risk with Geomechanics
Surej Kumar Subbiah (Schlumberger)
Stuck drill pipe, lost hole, severe mud losses, unable to hydraulically fracture the formation, well shut down due to sand production, early water breakthrough. Sound familiar? These incidents can cost E&P companies millions of dollars.
Geomechanics combines geology, geophysics, petrophysics and rock mechanics in order to describe state of earth stresses and rock mechanical properties. This can be done along a single wellbore, or in 3D field scale, and the results are presented in what is known as the Shared Geomechanical Earth Model. This model helps in the understanding and managing of the risks associated with rock deformation, which in turn helps minimize operational risks for the life of the field from exploration to abandonment. Examples include wellbore instability, sand production, hydraulic fracturing, injectivity, subsidence, compaction, fractures reactivation, and thermal effects.
This presentation aims to increase awareness as to how one and the same Shared Geomechanical Model can be used by different departments in an E&P company for their operational planning, with focus on drilling and completion activities.
Based in Abu Dhabi, Surej Kumar Subbiah is currently the Principal Geomechanics Lead for Schlumberger Middle East. Surej holds BS and MS degrees in petroleum engineering from the University of Technology Malaysia, with specialization in geomechanics. He spent the first five years of his career in an academic environment as a Research Associate and a Lecturer before he joined Schlumberger. With 21 years of experience, Surej has been involved in many applied geomechanics projects from well centric to 3D field scale, and conducted training courses in geomechanics for NeXT as well as SPE Netherlands and SPWLA Abu Dhabi. He is currently 2016/2017 SPE Distinguished Lecturer.
After the talks there will be the opportunity to socialise with fellow professionals over drinks and snacks.
Doors will open for registration and coffee at 3:30 pm and the talks will commence at 4:00 pm. The social hour will begin at 5:30pm.
Thanks to the generosity of our sponsors, attendance will again be free. However please inform us of your intention to attend before Tuesday 30th May 2017 by clicking on the RSVP link below, or by sending an email to firstname.lastname@example.org with your name, position and affiliation.
