De-risking Seismic Amplitude Interpretation by 3D Seismic Volume Detuning
Amplitude maps extracted as horizon attributes from 3D seismic are important tools in
exploration, appraisal and field development in many geological environments around
the world. Geophysics and rock physics help us to relate seismic amplitude maps to
many physical properties important in exploration and production, including changes in
lithology, porosity and the presence of hydrocarbons, especially gas. However,
amplitudes derived from seismic data are also affected by tuning, whereby the
amplitude also responds to reservoir thickness changes independently of any lateral
property change in the reservoir properties.
Thickness related tuning can easily double amplitudes in seismic, often being the cause
of significant reflector brightening in seismic data. By comparison, even a very strong
gas saturation effect in a soft sand reservoir may only change amplitudes by 25%.
Thickness related tuning is well understood in geophysics, but the basic principle of
removing tuning effects from amplitude maps is not widely applied. Detuned
amplitudes can also be used for computing seismic net pay. However, published
methods are based on detuning of maps extracted from seismic.
A new and novel technique has been developed which directly detunes the 3D seismic
traces themselves. The advantages of direct detuning of 3D seismic volumes include
the ability to investigate the whole trace amplitude response (not just a window or
extraction), generation of tuning curves without seismic data picking, rapid updating
and modification of parameters and improved stratigraphic and quantitative
interpretation.
The method is demonstrated on several real world datasets and results from a number
of different geological scenarios are highlighted. These include detuning the seismic
response from a UKCS Southern Gas Basin Rotliegend/Carboniferous target and a CNS
target which includes Jurassic, Zechstein and Rotliegend reservoir intervals. A
contrasting example from the Sea Lion Field, North Falkland Islands Basin will also be
shown.
Earthworks Sponsor Stoneley
Lecture
Once again Earthworks will be sponsoring the PESGB
Stoneley lecture 2014. Last years lecture was a great
success with Hugh Dennis. Come and meet the
Earthworks team after this years lecture on March 11th
2014. Details can be found at

Earthworks Reservoir Partners up with
ExploHUB
Earthworks Reservoir has entered into an agreement with the University of
Aberdeen’s ExploHUB training centre for the provision of its revolutionary
prospect evaluation software HIIP™.
In doing so Earthworks Reservoir identifies the importance of training
tomorrow’s exploration geoscientists and recognises the value of
introducing trainees to industry standard software, technologies and
capabilities as they embark on their future careers.
Announcing Release of HIIP Version 2.2
HIIP™ is a depth structure uncertainty and volumetric calculator tool for fast and easy
computation of field and prospect volumes and will be of value whether working in
exploration, appraisal or field development.
Running under Windows operating systems HIIP™ is a Java-based software package. Easy to
use and portable, HIIP™ can be run on laptops or desktop PCs and is ideal for rapid testing of
volumetric scenarios. Whether in the office or data room, HIIP™ is an essential tool for
geoscientists, new ventures and asset managers.
HIIP™ allows the user to either create or load existing depth maps and generate multiple
geostatistical realisations of depth structure in order to estimate the full range of depth and
volumetric uncertainty over a particular area of interest. A comprehensive set of geological
scenarios can then be tested in a short time period to come up with GRV ranges. Play and
prospect risk factors and probability distributions for petrophysics, fluids and recovery can
then be set in order to make probabilistic calculations of HIIP™ (Hydrocarbons Initially In
Place) and Reserves.
HIIP™ is also available on mobile devices - currently only available on Android.

Blueback Reservoir AS and Earthworks E&R announce the release of the Earthworks Seismic
Inversion Petrel™ plug-in software.
The Earthworks Seismic Inversion plug-in for Petrel (ESI™) is an ultra-fast full featured
seismic inversion software enabling effective use of impedance data in the reservoir
modeling workflow. The plug-in is fully integrated with Petrel using Petrel native data
objects, and makes advanced seismic inversion accessible and useable to the Petrel user
community.
The new Petrel plug-in product is commercially available and is ready for download from the
Schlumberger Ocean** Store.
A free trial version is available for a limited time period. Contact Blueback Reservoir for
more information around installation, training and testing of this new Petrel plug-in product.

EAGE 2011
Earthworks are extremely proud that Ashley Francis (Managing Director) was the
recipient of this year’s Nigel Anstey award. This prestigious recognition by the
EAGE highlights the technical contribution Ashley has made to the industry with
regard to Earthworks' Inversion methods.
The Nigel Anstey Award is presented for "a contribution of distinctly valuable and
tangible bearing on one or more of the disciplines in our (EAGE) association."
The EAGE presented this award to Ashley "in recognition of his very substantial,
original and diverse contribution to seismic inversion and geostatistics, and to the
quantifying of uncertainty and risk. He has been a major influence for the
widespread adoption of stochastic inversion technology in practical reservoir
characterisation work. His extensive publications - especially his two papers in
First Break - and lectures have helped considerably to publicise and also to
demystify stochastic modelling, and to move it into the realm of an everyday tool
in geological modelling. Thanks to the successful launch of his company Earthworks, he has
successfully developed high speed stochastic inversion software to allow the rapid
commercial application of the technique. Ashley Francis' other technical contributions, and
his active participation in conferences define him as a geoscientist who has made a very
major contribution to geoscience over more than two decades."
