Q: How does Geosat’s advanced remote sensing, nonseismic geophysical and geochemical methods improve the success rate for the detection of oil and gas fields?
A: Our InnoEx method delimits a trapping mechanism and defines if there is a hydrocarbon system below the trapping mechanism. Before performing any costly 2D or 3D seismic acquisition survey, Geosat can define the most prospective hydrocarbon areas of a block. This first step reduces the original area to a tenth; therefore, unnecessary geophysical or geochemical groundwork can be avoided. In other words, we create evidence of the existence of hydrocarbons. Meanwhile, seismic only defines a structure, which may be a trap, but it does not clarify if that trap is also filled with hydrocarbons.
Q: How do Geosat’s technologies complement existing exploration technologies used in the oil and gas industry?
A: The dominating technology in oil and gas exploration is seismic surveys. According to the AAPG (American Association for Petroleum Geologists), in a study of over 1100 wells worldwide, the average success rate of 2D seismic is 13%. This is where our InnoEx process comes in; it reduces time and cost, and at the same time, increases the probability of success from 13% to over 80%. In addition, 55% of the assumed oil and gas reserves in the world still have not been found, and seismic alone will not be able to find these remaining resources.
InnoEx defines the socalled positive anomalies, the potential areas that have a trapping mechanism and an active hydrocarbon system. With the exploration approach of using first a Geosat study like InnoEx, we are reducing both cost and time. InnoEx is also ideal for sensitive areas; it is non-invasive, environmental friendly, and even the groundwork needed to define the optimum drilling locations does not require huge machines; as a result, there is no ground destruction on the terrain.
Q: What have been the highlights of Geosat’s first projects, and what has been the feedback from your clients? Which achievements are you the most proud of so far?
A: Salis S. Aprilian, President Director of Pertamina EP, confirmed that the Geosat exploration concept is superior to 3D seismic, because it produced eight independent levels of information, in comparison to one level of 3D seismic data acquisition. Frankly speaking, such a statement from a NOC’s President Director – and geostatistical expert – is a confirmation to me that our exploration concept is the solution to the industry’s problem.
Q: How do you integrate the great variety of data you collect – thermal, geological and magnetic data, among other types of data – in order to more accurately quantify the exploration potential of a given area?
A: Our technology is based on the evaluation of satellite image processing (remote sensing), and geo-data interpretation, for which we have developed very precise software for the integration of multiple data in order to define various information levels and optimum drilling locations. The use of satellite data is nowadays accessible all over the world; there are more than 80 commercial satellites circling the world, hence the available data is vast. In addition, Geosat Technology became a showcase project of the European Space Agency (ESA) and has access to satellite data resources.
Q: How would your services apply to Pemex’s exploration activities?
A: InnoEx is mainly an onshore technology. Mexico has large unexplored potential on onshore areas which could be cost and time eectively surveyed with this technology, resulting in increasing the probability of successful wells being drilled by 80% or higher. Geosat could contribute a tremendous input to stop the fast declining oil production by finding new resources. Additionally, the application of our technology will help Pemex reduce the exploration costs and will increase oil and gas production much faster than through traditional exploration concepts.
For these reasons, we have recently opened our representative o·ce in Monterrey. I am confident that we can achieve our ambitious plan to contribute substantially to the development of Mexico’s quest for oil and gas reserves in a faster and eco-friendly manner. We are already talking to Pemex for innovative research studies on Mexican ground and will develop this further this year.
