Spotlight Speaker: Abhishek Goswami, Shell UK
With just over 6 weeks to go until PETEX 2018, we want to introduce you to another speaker from the PETEX technical programme! This week we are speaking to Abhishek Goswami from Shell UK. His presentation March of the Penguins – Using Full Broadband Seismic Imaging & Interpretation to Add Value to the Opportunity Portfolio is taking place in the Main Auditorium at 16:30 on Tuesday 27 November. We spoke to Abhi about Shell’s Penguins field and what he will be presenting at PETEX.
The installation of the FPSO vessel for Penguins field in the northern North Sea is a first for Shell in almost 30 years, why now, and why the North Sea?
Shell has had a presence in the Northern North Sea for over 40 years. The Penguins Fields, discovered in 1974, were brought online in 2001 with 9 subsea development wells producing co-mingled oil and gas condensate fluid and tied back to the host, Brent Charlie, 65km south via multi-phase pipeline. With a strategy focussed towards growth from the core production assets in the North Sea and maximising economic recovery, the plan is to continue to produce beyond the cessation of production of Brent Charlie. Redevelopment of the Penguins cluster will be achieved by drilling 8 additional wells and connecting these along with existing wells to a local FPSO hub.
What imaging techniques and interpretation will you be presenting at PETEX 2018?
One of the key enablers for achieving Final Investment Decision on the redevelopment project was the identification of additional volumetric opportunities and generation of a set of refined and optimised future infill targets using Broadband seismic data.
Its impact on the result can be summarised by a set of incremental steps adopted at the processing and interpretation stage that added value to the opportunity portfolio:
1. A robust velocity model to improve fault-plane imaging. This resulted in helping understand compartmentalisation and juxtaposition studies leading to better structural definition within all fields in the cluster. It also helped identify potential Geohazards and aided well placement decisions.
2. Application of advanced interpretation workflows on Broadseis data including Waveform classifiers, spectral decomposition and Sculpting helped improve structural definition and for predicting lithology at reservoir level.
What do you hope to get from PETEX 2018?
I’d like to engage with my industry colleagues and peers and get a feel for how Geoscientists need to redefine/re-calibrate their roles in the field of sustainable energy development. I’d also like to get a better understanding of how to recognise and turn any disruption (e.g. machine learning) into an enabler for my organisation.
