Message from the President
Firstly, we are pleased to report that we had a very well attended June evening presentation
by Jim White who certainly qualifies as an LPS "distinguished" lecturer. His convincing talk
on Magnetic Resonance Radial Profiling to identify condensate and light oil generated a very
strong debate.
We also have a number of equally interesting events coming up in the near future:
On 16th July evening Andrew Kingdon from the British Geological Survey should illustrate
the link between subsurface disciplines through: The contribution of geophysical and other
logs into the definition of structures and physical properties. See below for a fuller abstract
of this, the next evening talk at Burlington House.
After the summer break, on 17th September, Dr Branko Bijeljic of IC will be our evening
lecturer. He will report on the latest work from IC's Pore Scale Modelling Research group,
with emphasis on the petrophysical aspects of C02 injection/sequestration as a potential
tertiary oil recovery scheme, a hot topic as our industry looks to be more carbon neutral in the
future.
Our schedule of One Day seminars is in place for the rest of the year. First to run is our Rock
Physics/Rock Mechanics seminar at the Geological Society on 27th September. Second up is
our 3D Immersive Visualisation II seminar to be held at BP premises at Sunbury-on-Thames
BP. This has now been re-scheduled for the Wednesday 17th October.
This is also the time in the year when we have to start to think about the topics of next year
seminars and we would like your feedback to select three out of the four topics below:
- Statistics in Petrophysics - geostats, mapping etc.
- North Africa II
- Storage - gas, CO2 sequestration etc.
- Time lapse logging, saturation monitoring, subsidence monitoring, tying into 4D seismic.
- Basic FE Seminar : Classic Logs and Classic Analysis.
On other subjects, our VP Membership Assia Belahaouas is hard at work and pleased to report that we now stand at 115 members for 2007. Well done Assia!
Our VP External Relations, Steve Hobson, reports that Universities were contacted in April for the 2007 LPS's student prizes and so far we have received two nominations: Dean Wilson from Durham and Sam Matthews from Leicester. Congratulations for reaching the short list.
Finally I must recommend that you have a look at the growing (in content) LPS website. It even includes, or will include in the near future, some job adverts! Thanks to Iain Hillier for spending a considerable amount of his valuable time on this: Find us at www.lps.org.uk

LPS Evening Meeting - July 16th, 6 pm at Burlington House:
The contribution of geophysical and other logs into the definition of structures and physical properties
Andrew Kingdon, British Geological Survey
In 1999 the Digital Geospatial Model (DGSM) set out BGS' vision to take geological
mapping of the UK land surface from two dimensions into the third dimension.
With high quality 3D models now available for many areas of the UK within BGS there was
considerable discussion about extending this further by attributing models with data derived
from geophysical logs to attempt to map physical property variation across the UK. There
was just one problem, it didn't work.
So what do you so when a project fails to deliver? In BGS it has led to a complete rethink of
the way that BGS handles the use of geophysical log data and about the way we manage
data.
BGS is the national archive for geophysical logs for the UK land mass but has no capability
for acquiring logs over 250 metres depth. With very limited resources we are also unable to
acquire new data so are reliant on data deposited by energy, water and waste companies and
civil engineers. With all these disparate data source and lack of common standards, how do
you decided what is useful and what should be ignored, especially when it is the only data
available to you?
This talk is as much about the archaeology of geophysical logs as it is about understanding the
stratigraphy of the UK.
LPS Autumn One Day Seminar
The LPS autumn seminar; "Integrating Rock Physics with Petrophysics for Improved
Reservoir Characterisation", is scheduled for Thursday 27th September at the Geological
Society at Burlington House, Piccadilly.
Who Should Attend?
Petrophysicists, geologists, reservoir engineers, and geophysicists.
Why?
Integrating petrophysics with rock physics plays a critical role in providing the necessary
information for reservoir engineers, geologists, and geophysicists to intelligently judge the
risks and opportunities involved with developing a well or an entire field.
Petrophysics and rock physics can identify rock properties necessary to construct a model of
the subsurface, directly reduce risk, improve process efficiency, enhance overall production,
and increase the rate of return of economic assets.
The technical program includes:
An introduction to rock physics; Data acquisition programs for successful geomechanics
projects; Acoustic measurements on core; Pore pressure prediction, Wellbore stability
analysis, Coupled geomechanical and production simulation modelling; Stress dependency of
mechanical and petrophysical rock properties; Fluid substitution in shaley sands; The
application of rock-physics modelling to AVO interpretation, Petro-elastic modelling for 4D
seismic interpretation.
Presentations by:
Schlumberger, Rock Deformation Research Group (RDR), Petro-Canada, Ikon Science, Rock
Physics Associates, The Herriot-Watt institute of Petroleum Engineering, Fugro-Jason,
Southampton Oceanography Centre, SINTEF Petroleum Research, GeoMechanics
International Inc, and others from the consultant and oil company communities.
