Ecopetrol, formerly known as Empresa Colombiana de Petróleos S.A. and sister company South American Gulf Oil Co. dating to the 1930s which were taken over by the state owned Ecopetrol in the 1970s) is the largest and primary petroleum company in Colombia. As a result of its continuous growth, Ecopetrol forms part of the Fortune Global 500 and is ranked 303, it belongs to the group of the 25 largest petroleum companies in the world, and it is one of the four principal petroleum companies in Latin America.

Physical and geochemical characteristics of produced petroleum from the central region of the Llanos basin, Colombia, were analyzed to understand the petroleum charge history and alteration processes. Petroleum properties in the study area are the result of the complex charge history of the oil fields. The amount of gas in fluids is controlled by the migration distance from the late or, possibly, the current generation kitchen located beneath the foothill deformation zone. Gas influx decreases toward the foreland domain, as indicated by lower values of the gas-oil ratio and saturation pressure. The API gravity of the oil samples is mainly controlled by the intensity of biodégradation. Marine-sourced oils accumulated in shallow reservoirs of the foreland prior to the onset of Andean deformation. Those fluids were subjected to different levels of biodégradation, depending on the time they remained at reservoir temperatures lower than 80°C (176°F) and before being buried to their maximum depth. Geochemical data suggest multiple charge pulses from different source kitchens of two main types of source rocks, as well as different biodégradation levels. The proposed petroleum charge and alteration model allows prediction of the temperature history of a reservoir and the most likely physical properties of the petroleum at a specific location. The model can be used as an exploration tool to assess the risk of charge prior to drilling in unexplored areas of the basin. Copyright ©2015. The American Association of Petroleum Geologists.

Areas of resonance signals present in 12 frequency bins of the 1H NMR spectra of the vacuum residues of five Colombian crudes and a blend were correlated with their SARA components and some physicochemical properties. The residues studied were obtained from light paraffinic to heavy aromatic Colombian crudes. Correlations between the NMR spectra and properties were obtained with partial least square PLS and multiple linear regression MLR. Prediction models for SARA obtained by PLS had R2 > 0.97 while CV - q2 was between 0.92 and 0.99. Models obtained with MLR for SARA showed a high Rad 2 for the first three components and a lower one for asphaltene. The R2 of the prediction models for density, API Gravity, S, N, Ni ppm and wax %m content plus nC5- and -C7 insolubles were >0.988 while CV - q2 was between 0.87 and 0.99. The proposed correlation methods are fast and less costly than the conventional ones. © 2009 Elsevier Ltd. All rights reserved. Source

This invention relates to a manual tool for safely removing undesired taps, connected illegally and controlled by means of locking valves in fluid transport pipes (especially oil and derivatives thereof) and with pressures present of up to 690 kPa (100 psi). The tool according to the present invention is formed by a handle, a handle shaft, a packing gland, a main body, a draining valve, and a gauge adapter or wood plug, which is inserted by friction in the perforation to be blocked, forming a temporary seal therein while a definitive metal patch is fitted and soldered to the pipe. The invention also includes the method for safe removal of valves fitted to fluid pipes with said tool.
