Workshop Overview

The focus of oil and gas exploration has moved into “geologically unfriendly” frontier regions where structural complexity and hydrocarbon system fundamentals are significant challenges. In deepwater and other frontier environments, large volumes with high resource density and limited compartmentalization are required that can be appraised and developed with a minimum number of wells. Whereas leads and prospects may show seismic, CSEM, and geochemical anomalies, many plays are characterised by poor data quality and structural complexity which requires new data interpretation concepts in order to reduce drilling risk. The interpretation of data from individual geophysical methods is often plagued by non-uniqueness, which leads to a range of subsurface images and interpretations for the same targets. Multidimensional full-physics modeling and simultaneous inversion of geophysical measurements from methods based on fundamentally different phenomena (e.g. wave phenomenon in seismics and diffusion phenomenon in CSEM), have recently allowed a major advance in our ability to characterize geological heterogeneity or map complex reservoirs at different spatial scales. Joint interpretation, inversion methods, image-guided inversion are beginning to produce models that are in better accord and closer to the true target property distribution than separate inversions of data from single methods. Recent advances in structural and non-structural approaches to joint interpretation and inversion now make it possible to objectively combine a variety of field data to generate subsurface images with improved accuracy and structural or petrophysical conformity.

Objectives

The aim of this workshop is to present new developments in integrated geophysical imaging and geochemical interpretation of the subsurface, with emphasis on real-life applications relevant to hydrocarbon exploration in frontier regions.

Target Audience

Geoscientists and Exploration Managers of all E&P Companies and Practitioners in Government Agencies and Academia.

Programme Overview

We invite contributions involving, but not limited to:

  1. the development of realistic coupled multi-physics-based or integrated predictive models of subsurface reservoirs;
  2. joint inversion approaches especially for full-waveform seismic, electromagnetic, and potential field data and their applications in characterizing the top 5 km of the subsurface;
  3. improved structural, lithological, petrophysical, and geohazard predictions (including over-pressure) underpinned by integrated data analysis or joint inversion;
  4. computational approaches to handling large volume data in 3D joint geoscientific inversion; 
  5. integration of seabed geochemistry with seismic and CSEM exploration data.
