Early Cretaceous Conomita outcrop: structural analysis of syn-sedimentary gravity-driven deformations (NE Venezuela)

October 10, 2020
U3 Explore
An updated analysis of Conomita Fold outcrop (Barranquin Fm.) was performed using an image of a field-trip guide-book organized by PDVSA in 1993: Excursion al Frente de Montaña, Venezuela Oriental (Stop # 5). “Remote” structural analysis carried-out along this outcrop reveals the existence of several deformation episodes related to gravity-driven processes. Conomita fold appears to be a slump feature generated in a deltaic setting. Early Cretaceous rocks were strongly tilted during the Miocene-Recent tectonics phase contemporaneously to El Pilar right-lateral strike-slip fault.

  • Early Cretaceous rocks were strongly tilted during Miocene-Recent tectonics phase  contemporaneously to El Pilar right-lateral strike slip fault.
  • Amore exhaustive structural analysis should take into account the original thicknesses of  para-sequences described throughout  the outcrop. A valid restoration study needs to consider the original thicknesses prior to compaction because “soft” deformations occurred during early stage of Barranquin Formation sedimentation.
  • This outcrop could  be used eventually as an analog structure for hydrocarbon reservoirs and fault-seal analysis exercise.
  • Conomita slump  was previously described in: Cabrera, E., Campos, V., Chigne, N.,Hernandez,  Fr. Galea, O. Macsotay and V.Vivas, 1988 Excursión al Frente de Montaña, Venezuela oriental, III Simposio Bolivariano de Cuencas Subandinas,Caracas,51 pp.

The use of synthetic curve to estimate TOC content in Vaca Muerta Formation, Neuquén Basin, Argentina
Sep 11, 2024
Ricardo Sebastian Martinez

The Vaca Muerta Formation in the Neuquén Basin, Argentina, is a highly promising unconventional reservoir, but understanding its productive limits and sweet spots requires extensive geochemical data. Unfortunately, such data is scarce, especially around major production blocks, with only a few wells providing it. To address this, the report generates a synthetic curve based on the sonic log (DT) to estimate Total Organic Carbon (TOC) content.

Framework for statistical analysis for assessment of return on investment in Venezuela
Feb 6, 2024
Katya (Ekaterina) Casey

With statistical analysis used in various economic forecasting, it is essential to have a relevant framework to group parameters characterizing the technical aspects of the projects into meaningful analysis. In the Petroleum industry, lease blocks are selected based on the remaining reserves' potential and geologic insights to unlock possible discoveries even in mature basins. Significant upside potential exists in Venezuela's petroleum assets, where the oil and gas industry stopped a natural petroleum province maturation process due to political reasons in the early 2000s.

The authors have used those data to generate a play-level analysis of the petroleum system on the Somali passive margin. Clastic and Carbonate plays have been identified. It has been recognized that the Jurassic source rocks in the basin, unlike the equivalent interval to the south, are largely still within the oil window. This abstract summarizes the portion of that study describing the carbonate play.

John Pantano

Offshore Eastern Africa emerged as a significant new petroleum province through the second decade of the 21st century (2018; Davison and Steele, 2018; Sayers, 2017; Davidson et al., 2018). A combination of Jurassic source rocks (unpenetrated but inferred, e.g. Sayers, 2017) and Cretaceous and Tertiary clastic reservoirs came together to deliver world-class gas discoveries in the offshore basins of Kenya, Tanzania, and Mozambique.

Reservoir Characterization in the Somalian Deepwater Frontier: Using a Worldwide Database to Predict Reservoir Quality
Aug 14, 2023
Stephen Cossey

A searchable database of worldwide Deepwater reservoirs (the Cossey Deepwater Database) was used to define sets of analogue data for clastic play fairways mapped in offshore Somalia. This methodology was chosen because the Somalian margin has minimal available well data, but does have good quality 2D seismic data from which reservoir presence and depth could be inferred. Using the analogues defined in this way enabled the definition of credible predictive ranges under a variety of scenarios to input to volumetric models, thereby capturing the shape of the uncertainty distribution.

Neogene structural evolution along southern Gulf of México (Campeche sub-basin)
Mar 11, 2022
Carlos Giraldo

Neogene's tectonic evolution of the southern Gulf of México (Campeche sub-basin) is associated with intense salt-mobilization, and it can be separated into 3 main episodes: 1. Late Oligocene (?) - early Miocene to middle Miocene: salt-rooted thrusts running parallel to the Paleogene Zongolica front that generated a series of northwest-southeast oriented anticlines.. 2. Late Miocene – Pliocene extension: NE-SW Macuspana depocenter. 3. Pliocene – Quaternary extension: NE-SW Comalcalco. This paper will be presented at the 83rd EAGE Annual Conference & Exhibition 2022 in Madrid.

Juan Francisco Arminio

Hydrocarbon accumulations in a Tertiary carbonate play in sedimentary basins of northern South America range from small to medium to giant. The fields are located both onshore and in shallow waters of the southern Caribbean Sea. Recent discoveries and wide variation in the play's field sizes generate renewed interest in the exploration in the region onshore and offshore. The exploratory risk could be reduced by a better understanding of controls on the field size distribution and reservoir presence and/or quality.

One of the more recent technological advances to gain traction in Oil and Gas is the application of Machine Learning processes to solve geoscience problems, such as those related to trap and reservoir identification in salt basins. With ever-increasing data processing capacity and decreasing processing costs, it's only natural for oil and gas companies to adopt increasingly efficient ML applications, pushing them to the limits of what they can do. ML is here to stay from that point of view, and investment in developing and refining ML technology will only grow with time.

Remote Sensing Satellites are great because of its availability, cost-effectiveness, and easy to program tasks. On the other hand, in most countries, you have to go through a lengthy process to be able to take an aerial photograph (digital or analog) if you use an aircraft. This is one of the many advantages to use satellites instead of aircraft and also It is more practical from the project standpoint. But sometimes you need high-resolution imagery to perform engineering or cadastral grade work. Would it be neat to be able to do it with satellite imagery instead?

Basin and play exploration are inherently governed by the management of risk and uncertainty at the portfolio level. Exploration investment decisions biased by risk-averse teams are susceptible to first-order basin statistics which may reflect a historical “poor” exploration history and exhaustion of existing play concepts. New concepts, new models, new thinking, and consideration of alternatives often result in a paradigm shift despite previous negative results.

This analysis uses the data collected over March 25th- April 5th. By the digital nature of our survey, the responses are biased towards technically enabled companies and individuals that were set up for occasional remote work. We analyze 1- the overall level of the system preparedness for such an extraordinary situation when the majority of the workforce is working from home, where the entire family is streaming homeworks, videos, and videoconferencing; 2- social aspects of the remote working; 3- feedback on the support provided for remote workers and ideas on post-crisis recovery

Ñirihuau Basin Report, Argentina
Jan 16, 2020
Ricardo Sebastian Martinez

Located in southwestern Argentina, it covers around 15000 Km2, with more than 10.000 ft. thickness in the depocenters. The basin has more than 100 years of exploration history started with the exploitation of 10 barrels a day from 4 wells in “Arroyo de La Mina” oil seepage. This report summarizes the new exploration ideas, based on geochemical data and outcrops description that allows the existence of a hypothetical new petroleum system. This idea generates high exploration potential in undrilled deep sections of big structures.

This report contains an exploration review of Colorado Basin, located in southeastern Argentina, it has onshore and most extensive offshore sections with more than 125000 Km2 of total extension. The basin has more than 70 years of exploration history, with a few wells drilled, one of them recovered 39º API Oil from Early Cretaceous Syn-rift sandstone. Three main plays were identified, with high exploration potential: Rift Margin Play, Continental Slope Play, and Thrust belt play.
