Earthworks Reservoir in GeoExpro May 2018

We are delighted to announce that Ashley Francis Director of Earthworks Reservoir has been published once again in the GeoExpro magazine. Use the following link to read the first part of the article. The second part yet to be published. see here for updates in future months. https://www.geoexpro.com/magazine/vol-15-no-2

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 http://www.pesgb.org.uk/news/2014/jan/17/stoneley- lecture-11-march-2014/

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. To request a copy of the latest release please email 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. ** Mark of Schlumberger

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."
