19-20 NOVEMBER 2019 FIRST HGS/EAGE CONFERENCE ON LATIN AMERICA • 1 WELCOME TO the First HGS/EAGE Conference on Latin America themed “South American Petroleum Plays for Future Decades of the Third Millennium”

We are pleased to welcome you to the 1st HGS/EAGE meeting on Latin America that will take place in Housten, USA from 19–20 November 2019. We are excited to offer you this interesting event in Houston. It will bring together the knowledge of two well known societies, namely HGS and EAGE, the Europen Association of Geoscientists and Engineers.

While the petroleum industry is still experiencing the biggest economic downturn seen for decades, our industry-based colleagues and academics continue to bring new tools, influence and understanding to exploration and production activities. The world needs energy and therefor it needs you to participate in events like this. The downturn also offers opportunities especially in the field of new technologies and efficiency.

We strongly believe that the joint HGS/EAGE 2019 event will bring together a strong, successful conference focused on Latin America and widely attended by academic and industry participants. We are preparing a program with broad appeal, scientific focus and networking opportunities. We are expecting 300 participants from the US, Europe and Latin America with oral and poster presentations. In addition an exhibition is present to facilitate knowledge transfer and business among the Geoscience community. On behalf of the committee , we hope to see you in Houston!

Cheryl Desforges, Mariela Araujo Fresky and Steven Getz Conference chairs

She joined Wood Mackenzie in 2017. The corporate landscape is diverse, as are the plays available Alana holds a BSc Honours degree in Geology & Petroleum to explorers. Geology, and an MSc in Integrated Petroleum Geoscience from University of Aberdeen. While technical success rates trended below the global average, the high proportion of oil helped sustain relatively high commercial success rates. Nonetheless, full-cycle economics have been very tough for the industry over the past ten years. In Latin America, annual full-cycle returns averaged 8% - a little below the global average of 9%.

While large companies are focused mostly in deepwater plays with potential for giant discoveries, smaller companies are focused on high returns from more modest prospects in mature basins with established infrastructure – for example onshore in Colombia’s Magdalena Valley and offshore in Brazil’s Campos basin. These basins, while mature, are not without their own complexities. Whether the prospects are in small, tectonically complex structures in onshore settings, or below salt in giant stratigraphic traps, the most successful companies are those applying new concepts and technologies to their positions. n

The deep water hydrocarbon system of the Guyana/ Canyon then cut across the shelf and delivered over Suriname Basin can be summarized by understanding the one second of sediments from this single point source interaction between three river systems and two source to the deep water, which profoundly impacted the rocks. We define these three river systems as an Aptian hydrocarbon system. The larger Berbice drainage system aged “Demerara System”, an Upper Cretaceous “Berbice supplied second cycle sediments from a Pre-Cambrian System” and finally the Miocene/Pliocene aged “Amazon Quartzite provenance for the excellent quality deep System”. The two deep water source rocks are the 108 ma water Campanian/Maastrichtian reservoirs. This Berbice, Lower Albian (Oceanic Anoxic Event, OAE-1) and the 90 ma Upper Cretaceous sediment also provided the significant Cenomanian/Turonian (OAE-2). overburden necessary to push the Lower Albian, OAE-1, source rock into the oil generation window when both Jurassic to Lower Cretaceous (200 to 108 ma) reservoirs and top seals are present.

The sediment from these rivers is stored in the fluvial, highlands in both Africa and South America. This resulted near shore and shelf environment, so the deep water basin in deposition of 2-3 seconds of clastic sediments forming a is starved and receives a very low sedimentation rate.

Geophysical exploration in South American Pre-Andean analysis, i.e. which shows a decent fold of coverage. As a rift basins proves to be a very complex task due to rough consequence, tomographic approaches are key to unlocking topography, complex subsurface geology and often fast or the potential in shallow subsurface velocities. Examples Stacking velocity analysis, residual statics and migration velocity analysis benefit from all highly variable near surface velocity. Furthermore, surface show the advantage of tomo statics over refraction or steps described so far. With a proper basic statics, denoising and signal-to-noise conditions often do not allow for a seismic acquisition elevation statics. Another step forward in technology is Full enhancement any velocity analysis and residual statics delivers more reliable results. We design that fits the needs for the complex subsurface Waveform Inversion (FWI) on land data which still proves to present examples showing the impact of more reliable analysis results on the seismic image. imaging challenges. As a consequence, seismic processing be challenging but already shows some promising results. Data regularization may have a big impact on migration results. Rough topography often strategies that work in simpler settings do not lead to causes irregularity in shot and/or receiver locations. Such irregularity is the reason for satisfactory results: there are many datasets that have been Modern noise modeling methods with subsequent adaptive irregular fold of coverage which may result in migration artifacts due to data gaps. CRS reprocessed several times without much improvement substraction from the input data show good results processing along with 5D interpolation are modern regularization techniques with CRS even suggesting that there is no more information in the especially for near offsets. Near offsets usually suffer most working in areas where 5D often fails such as low signal-to-noise ratio, low fold of coverage acquired data. This assumption is often not true. It is from noise since the amplitude of shot generated noise just that the processing strategy needsand to stebeep adapted dips. Examples to willis highest show how on thoseregularization offsets.

The first key to successful imaging is the near surface velocity model and the associated basic statics solution. Pre-Andean rift basins are usually characterized by laterally highly variable velocities due to outcropping or eroded layers. Elevation or simple refraction statics must not be applied because they suggest structures in time domain which are due to velocity effects in the shallow subsurface. The aim of the basic statics solution is to remove shallow subsurface velocity effects up to Figure 1.

Further, most aspects of Atlantic opening history take some 75 m.y. to subduct. Accordingly, Pacific-origin have been satisfactorily correlated with geological plate tectonic models place the Caribbean lithosphere developments along the passive margins. However, at between Mexico and Colombia prior to the Cenozoic (e.g., least one aspect of Atlantic opening history has gone Pindell and Kennan, 2009). In truth, the Caribbean had under-appreciated in terms of recognition of its geological originated from much farther west as shown by subduction- manifestation, namely the phase of roughly N-S plate related Caribbean arc rocks and HP-LT metamorphic rocks convergence between North and South America in the of the frontal Caribbean sutures dating back to the Early Caribbean region since the Paleocene (Pindell et al., 1988; Cretaceous (Stöckhert et al., 1995; Maresch et al., 2009; Müller et al., 1999; several others since).

However, any inter-American attached to South America. Instead, the Proto-Caribbean Paleogene plate boundary development was overprinted oceanic (subductable) lithosphere has been torn free from by the younger, oblique Caribbean collision.

Paria and eastern Venezuela (Vandecar et al., 2003; Clark et al., 2008). There are two options for explaining how this For the few workers who still question whether the slab may have been torn. One option is to consider that Caribbean is far-travelled, a possible answer is that North the relative migration of the Caribbean Plate along South America-South America convergence has caused most of the America has driven a progressive tearing of the Proto- well-known contractional structures along northern South Caribbean crust from South America, directly beneath the America. However, for those who recognise the Pacific SE corner of the Caribbean Plate as it advances (Clark et al., origin of the Caribbean Plate, it must be acknowledged that 2008). However, this option does NOT account for the fact the inter-American convergence was underway while the that inter-American convergence began well before the Caribbean Plate was still some 1200 km west of its present Caribbean Plate had moved east of Guajira Peninsula. position with respect to the Americas. Thus, a significant portion of the inter-American convergence must be taken The second and, in my opinion, more feasible option is that up on structures that are not Caribbean-related. an inter-American convergent plate boundary formed that had little to do with the Caribbean Plate. Quantitative plate Mantle seismic tomography shows convincingly that the reconstructions demonstrate that at least 100 km of inter- Atlantic oceanic lithosphere dives westward beneath American convergence had occurred along northern South the eastern Caribbean Plate by at least 1500 km (van der America at any geographic point along the margin prior to Hilst, 1990; Levander et al., 2014; van Bentham, 2013; van the ensuing collision of the Caribbean Plate at that point.

These juxtapositions give interesting insights into hydrocarbon generation within the plate, while subsidence history curves help differentiate generation histories. Hydrocarbons in the plate tend to be situated on the edges of these subbasins, and certain terranes seem to be more oil-prone – even when considering for kerogen type. These results are investigated to better inference hydrocarbon potential within the plate. n
