Application of the Constrained Least Squares Spectral Analysis.

 Application of the Constrained Least Squares Spectral Analysis (CLSSA) as a Spectral Decomposition Technique in E-BD Oil Field within Bredasdorp Basin, Offshore South Africa

The main objectives of this study were:

• To investigate the performance of the CLSSA methodin terms of detecting geological features over a well-understood E-BD Oil field.
• To compare the CLSSA results with those from commonly used spectral decomposition techniques(STFT and CWT).

Sbonelo Ngcongo is a South African Petroleum Geoscientist and Entrepreneur. He was born and raised in Pietermaritzburg, KwaZulu Natal and moved to Cape Town in January 2006 to study Mathematical Sciences at University of the Western Cape. 

Ngcongo has been with PetroSA (South African National Oil & Gas Company), as a Petroleum Geoscientist since 2008 until 2021 and held several roles, including Senior Petroleum Geoscientist, Reservoir Geoscientist and Business Development Geoscientist of its New Ventures – Upstream Division. While having a full-time job at PetroSA as a Petroleum Geoscientist, Ngcongo considered to start his own consultancy business in Oil and Gas Industry. Currently, Ngcongo is based in Johannesburg, Sandton and consulting to Oil & Gas Companies, Banks, Private Investors, Government Agencies and Law and Accounting firms. 

Sbonelo Ngcongo holds a Master of Science Degree in Petroleum Geophysics from the University of Houston (Houston, USA). Sbonelo Ngcongo is currently enrolled in PhD (Application of Machine Learning in Oil & Gas Industry), at University of the Witwatersrand, Johannesburg. 

Ngcongo’s notable academic achievements are: He won the best international poster and paper Awards in Petroleum Geophysics at the American Association of Petroleum Geologists International Conference (AAPG), he was a Secretary and a Vice-Chairman of the South African Geophysical Association (SAGA, Western Cape Branch) and a member of SAGA/GSSA conference organizing Committee. Ngcongo has supervised Honors Degree Petroleum Geoscientist students at the University of Cape Town. 

Ngcongo attended international workshops of Petroleum studies in Houston (USA) and London (UK). 

Sbonelo Ngcongo is a speaker at local and international conferences on Petroleum Geoscience topics. He has delivered papers on a wide range of topics such as data analysis for Oil and Gas Industry, signal processing, spectral decomposition, seismic inversion, rock physics, hydrocarbon reservoir characterizations and Subsurface 3-D Geological Modeling.
