Expert recommends new explosion techniques to oil industries

A professor of Exploration Geophysics, Isaac Aigbedion on Monday recommended the combination of the controlled source electromagnetic technology (CSEM) and Seismic techniques for Offshore oil and gas exploration in Nigeria and West Africa for optimum results.
Professor Aigbedion of the Ambrose Alli University, Ekpoma said that CSEM technology had the capacity to be evaluated for less money and also ensuring that the best prospects were drilled first, adding that CSEM has the ability to detect the presence of hydrocarbon field layers in deep water areas, while the Seismic can help in obtaining high resolution structural images of the subsurface just as rock and fluid properties could also be derived.
He explained that subsurface resistivity information obtained from electromagnetic surveys could help detect and estimate the total hydrocarbon volumes more accurate than using only conventional seismic data, adding that the combination of the two methods would lead to a significantly greater understanding of subsurface properties.
“By integrating Seismic and CSEM data in a staged workflow, limitations of each can be overcome and the strength of each exploited CSEM has proved to be complimentary to Seismic and can significantly reduce risk associated with seal change volumes. CSEM surveys provide information that is more directly related to the presence of hydrocarbons, but the greatest Success rate can be archived by using both forms of measurements,” he added.
Meanwhile, the Edo State Oil and Gas Producing Areas Development Commission (EDOSOPADEC) has commenced rural electrification of Abudu and communities in its environs In Orhionmwon local government area of Edo state.
The Edo state government had ordered the provision and installation of 2, 5MV.33: 11 KVA transformers to boost power supply in the locality, while the benefiting communities include: for the first phase, Abudu, Oza, Evbuobanosa, Oghada, Itu, Ofien, Idudolor, Ugoneki, Igbogiri among others. But the state governor, Mr Godwin Obaseki, said that the project was aimed at addressing the perennial power problem in the areas, describing the development as a revolutionary in infrastructural development.
