A Large Heavy Oil Reservoir in Lake Maracaibo Basin: Cyclic Steam Injection Experiences
Proceedings of International Thermal Operations and Heavy Oil Symposium, 1997Abstract The Bachaquero-01 reservoir is located in the Lagunillas field within the Lake Maracaibo Basin in western Venezuela. This reservoir is divided into two zones: the lake area operated by Lagoven, S.A. and the land area by Maraven, S.A. both companies are PDVSA (Venezuela Oil Holding) subsidiaries.

Organic Geochemistry, 2011
The organic geochemistry of samples from 11 oil seeps was studied. The samples were collected from the Cachiri area, Carboniferous Region of Tule (Lake Maracaibo Basin, Venezuela), associated with the Tigre Fault. Biomarkers (hopanes, steranes, n-alkanes, acyclic isoprenoids, and aromatic steroids) were analyzed using gas chromatography-mass ...

Abstract Rain samples were collected by events from November 1988 to November 1989 at La Esperanza and Catatumbo sites. Dry deposition was collected only at La Esperanza. Volume weighted average pH values of the rainfall samples were between 4.23 and 4.64, individual samples reaching as low as pH 3.0.

In the central part of the Maracaibo basin, integration of recently acquired 3-D seismic and existing geological data has led to the definition of the Lamar sub-basin as an array of partially inverted half grabens which formed during Late Cretaceous and Early to Middle Eocene times as a result of transtensional episodes along older rift structures ...

This work synthesizes results from the application of land cover classification techniques and probability sampling of satellite imagery for estimating forest extent and deforestation in Lake Maracaibo Basin (Venezuela and Colombia). A forest map was produced using a semi-automated supervised classification routine on MODIS 8-day 500-m imagery acquired

The determination of eight heavy metals and nine water soluble ion concentrations in cellulose filters loaded with air particulate matter was carried out in two rural sites. The water soluble particles show a higher concentration of inorganic salts than those observed for other places of Venezuelan savannah.

The Center Lake Field is one of the most important light oil reservoirs in the Maracaibo Basin. Field production of {open_quotes}C{close_quotes} sandstones, Misoa formation, Eocene, started in 1968. Actual cumulative production is 630 MMBls, which represents 23% of the original oil in place. Flank water injection programs have been executed since 1976;

A new species of aquatic snake in the genus Pseudoeryx is described from the Lake Maracaibo Basin in northwestern Venezuela. The new species differs from P. plicatilis, the only other species in the genus, by having a nuchal band, a distinctive ventral coloration, the relative size of the genial plates and having different maxillary dentition.

Eocene clastic rocks of the Maracaibo Basin were deposited in an asymmetrical foreland basin formed during the oblique Paleogene collision between the Caribbean and South American plates. In this study, we use more than 300 wells and 2000 km2 (772 mi2) of seismic data in the central Maracaibo Basin to produce a detailed sequence-stratigraphic ...
