Olmedo-Pirity Basin

An RSDD-H research survey was performed on the request of a large LA company, in the north Argentinian part of the Olmedo-Pirity Basin with its complex geology, petroleum habitat and heterogeneous landscape ecosystem.  The survey covered the proven Palmar Largo, El Molino, El Chivil, El Chorro fields and the recent Proa discovery.  All fields were identified with confidence, and new prospective features were mapped.

The above RSDD-H example (normal and IPD displays) of  El Chivil area displays the data and landscape challenges that RSDD-H processing had to address.  This local district straddles the floodplain of Rio Pilcomayo and the more elevated Chaco plains: two terrains with completely different anomalous responses on RSDD-H data.  As a result, it wasn't possible to create a comprehensive prospectivity pattern on just a single processed scene.  To resolve the problem, two separate processings were performed - firstly  for the floodplain landscape unit (Figure 1) and secondly for  the Chaco plain landscape unit (Figure 2). These two were then montaged into Figure 3, idenitfiying the more complete extent of the Chivil field. This is normal RSDD-H surveying practice for significantly heterogenous landscape terrains worldwide.
