Earthworks Reservoir New Technical Note

Earthworks Reservoir has released a new Technical Note focussed on its unique Seismic Detuning technology DT-AMP, summarising technical material and case studies published at the Petex and Prospex conferences at the end of 2018.  The title is: “Improved Identification of Genuine DHIs and Suppression of False Anomalies using Interactive Amplitude-Thickness Crossplots and Seismic Trace Detuning” Founded on the continued success of these studies for our clients, Earthworks continues to provide both software and services that radically change amplitude analysis from seismic data.  The technical advantages offered by DT-AMP over other methods (such as grid-based approaches) are substantial, particularly where geological interpretation of amplitude maps is concerned.  These advantages include: Automated analysis of detuning directly in-situ on seismic data Amplitude-thickness crossplots automatically processed and generated No horizon picking or interpretation required for analysis or detuning Interactive highlighting of tuning on seismic Interactive in-situ detuning of seismic traces Interactive SNP Enhanced DHI analysis and Fluid Detection Very fast analysis and result delivery More recently we have further developed our ideas and understanding and have now developed additional analytical tools and a workflow within the software which improves the robustness of DHI analysis and reduces risk.  An example based on detuning over the Ardmore Field is shown below: Note particular attention to the crisp field outline after detuning, as well as the very bright tuned features central and north becoming more muted after detuning.  The presence of Rotliegendes reservoir in the south (green) is not evident in the original data, but clear in the detuned result.

A Simple Guide to Seismic Amplitudes and Detuning

Seismic amplitude changes may tell us something about reservoir lithology, porosity, and/or fluids. However, seismic tuning effects are potentially much larger than amplitude variations due to geological changes. Understanding this key concept is critical to effective seismic interpretation - published 2015 (issue 5) -

Earthworks Reservoir Engage with Local School to “Find Oil”.

Global Exploration and Production consultants Earthworks Reservoir engage with local school,

marking a year since the consultants expanded their operations to Aberdeen.

The primary 6 classes had been studying oil and gas exploration since the summer break and

wanted to learn more about finding oil and why it is in their local sea. Engaging with Ferryhill

School, John Sayer – Business Development Manager, provided a fun and informative afternoon

workshop. The 40 primary 6 pupils were taken on a journey that lasted around 250million years,

not easy in one afternoon.

The children were thrilled to learn the

origins of fossil fuels, the units of

source, reservoir and sealing rock and

how we as an industry find oil using

complex processes from Seismic Vessels

to Reservoir Modelling to identify such

entities; all of course in the language

of 10 and 11 year olds.

The afternoon was rounded off with a

spot of petroleum engineering. Divided

into teams of 5, the children were

provided with 25 drinking straws and some cello tape and briefed on building a

drilling derrick. The derricks were tested to see how much weight they could

hold, a bucket of rocks in true geological fashion. The subsequent testing

provided no winner with many structural failures being witnessed so the team,

who had built the best looking derrick, prior to testing, were deemed the


The afternoon was a great success and Earthworks Reservoir would hope that

maybe a future subsurface professional might just have been inspired to join our

industry when they grow up. Judging by the Q&A some of them would definitely

do well within the subsurface sector.
