Sub Basalt Exploration in Asia and Pacific Current Practice and Advances in Foothills Imaging

Announcing Two Joint workshops

Basalt is present in a wide range of basin environments including mid-oceanic ridges, subduction zones and intra plate settings. There are large prospective areas of the world’s sedimentary basins that are still less explored for sub-basalt targets. Imaging below basalt has always been a challenge for exploration. Penetration of seismic energy below basalt has always been a problem, Strong inter-bed multiples always mask the weak reflections coming from sub-basalt formations. Severe scattering of seismic energy due to heterogeneity of basalt layer further complicates the problem which results in the lowering of frequency content of the data and also velocity model building for imaging becomes highly challenging.

These challenges can be addressed to certain extent using new processing technologies and focused strategies. Broadband processing may help in enhancing the low frequency signal content of the data. Advanced data driven demultiple techniques may help to eliminate the multiples below basalt to bring out the hidden signals. Velocity flooding approach may help in preparing a better velocity model for migration. Very long offset data and converted wave data are also being used for exploration of Mesozoics below basalt. New approaches like these are continuously being applied in the seismic industry and improvements are observed in the imaging below basalt. Workshop will address the challenges of sub basalt exploration in Asia and Pacific.

Foothills are generally characterized by difficult near surface and complex subsurface geology. Exploration in these areas is immensely challenging in terms of difficult logistics, complex subsurface geology of thrust belt and hilly terrains right from data acquisition through processing to integrated interpretation of the dataset.The complex near surface, large variation in elevation and high velocity exposures, not only affects the statics but also generate strong ground rolls which mask the limited subsurface illumination. This also means velocity model building has to be performed under a low signal-to-noise condition in structurally complicated geological settings.

The conventional elevation statics based solutions do not provide the good results to handle above mentioned issues. Data driven statics computation approaches based on tomography derived refraction statics are able to handle the near surface irregularities more accurately. Horizon velocity analysis (HVA) provides the detailed lateral velocity variation along the marker horizon which may be missed by conventional velocity analysis that are sparsely spaced along the line. HVA is an efficient method to get velocity information at every CDP location along selected key horizons which will be structurally more consistent and geologically more conformable. Single arrival based Kirchhoff migration may have limitation in imaging due to subsurface complexity in such areas, necessitating the application of advance depth imaging techniques capable of using multi-arrivals of seismic energy.

Thus, a combination of tomography derived refraction statics techniques, HVA with advanced tools of imaging, is a promising approach for improving imaging in a thrust belt. Workshop will provide a opportunity to interact & discuss current practice and advances in foothills imaging.


Dehradun, the capital of Uttarakhand State is situated in the foothills of the Himalayas. The lush green valley in which this beautiful city is located, is surrounded by the Himalayas in north, the Shivalik range in south, river Ganga to its east and the river Yamuna to its west. Dehradun is spread in the area of 300 sq km and is situated at an altitude of 682 m. The language spoken here is Hindi and English. Total Population is 16,95,860. During February month average temperature of Dehradun remains 16 degree celsius and humidity 71%. Dehradun is the gateway to many tourist places like Mussoorie, Haridwar, Rishikesh, Badrinath, Kedarnath, Gangotri, Yamunotri, Tungnath, Rudranath and Madmaheshwar. Forest Research Institute and Indian Military Academy are beautiful places in Dehradun.

Nearest Jolly Grant Airport is at the distance of 26 km from the Dehradun city which serves Dehradun domestically, with regular flights coming in from places like Delhi & Mumbai. The nearest railway station is the Dehradun junction, which is well connected to major cities in northern India, primarily New Delhi. Regular bus services also ply to and fro Dehradun through an excellent roadways network.

About the venue The Geodata Processing and Interpretation Centre (GEOPIC), the venue of the joint workshops is located at Keshav Dev Malaviya Institute of Petroleum Exploration(KDMIPE) Campus of ONGC Dehradun. It has the largest computing facility and one of the few centers around the world where integrated processing and interpretation of different geo-scientific data from seismic to petro-physical, geological and reservoir engineering are carried out.Land and marine seismic data of Indian & Foreign basins is processed and interpreted synergistically at this centre which has world class state-of-the-art infrastructure backed by specialists. Since inception, GEOPIC transformed itself into a Centre for Excellence and today is one of the premier institutes of ONGC.
