Coiled Tubing Drilling on Lake Maracaibo

International Petroleum Conference and Exhibition of Mexico, 1994
Abstract Drilling through shallow gas zones can be a major hazard, especially in offshore operations. An innovative technique using tender-assisted coiled tubing (CT) drilling is presented, which allows the determination of hazardous shallow gas presence with minimum risk, prior to mobilization of a large drilling barge. One advantage of

Microbial Stimulation of Lake Maracaibo Oil Wells

SPE Annual Technical Conference and Exhibition, 1999
Abstract More than 300 oil producing wells have been stimulated with microorganisms in Lake Maracaibo, western Venezuela, since 1996. Most of these wells are managed by Tía Juana E.U. (Exploitation Unit), PDVSA E&P, Western Area, and belong to reservoir LGINF-05.

EFFECTS OF PETROLEUM ON ALGAL BLOOMS IN LAKE MARACAIBO

International Oil Spill Conference Proceedings, 1985
ABSTRACT On the basis of a one-year program of monthly in situ bioassays and sampling at 10 stations near the incubation site, a study on the effect of petroleum on the massive algal blooms in the northeastern coastal area of Lake Maracaibo has been made.

Scheduling Boats to Sample Oil Wells in Lake Maracaibo

Operations Research, 1978
Sampling oil wells is a routine operation that involves withdrawing, near the wellhead, a fraction of the liquid that flows from the well. This operation is not performed at fixed intervals, but with a frequency that varies from well to well and that also changes in time. Lagoven, S. A. operates some 3,000 oil wells in Lake Maracaibo, Venezuela, for a

Radioisotope Concentration in Lake Sediments of Maracaibo, Venezuela

AIP Conference Proceedings, 2007
Maracaibo Lake is one of the most important water basing and oil producing regions in Venezuela. Changes in the local environment have been monitored for chemical pollution in the past. For this study we selected a set of sediment samples collected in the shore and analyzed for its radioisotope content.

OIL POLLUTION STUDIES ON LAKE MARACAIBO. VENEZUELA

International Oil Spill Conference Proceedings, 1975
ABSTRACT The results of a 2-year study on the impact of oil discharges on the fishery resources of Lake Maracaibo, Venezuela, are presented. The lake system is described, together with relevant water quality, hydrographic, ecological, and fishery resources data. Sources of other types of pollution, domestic and industrial, are described,

REMEDIATION AND TRANSPORTATION PLANNING, LAKE MARACAIBO, VENEZUELA

International Oil Spill Conference Proceedings, 2001
ABSTRACT Lake Maracaibo in western Venezuela is one of the major oil-producing areas of the world with over 12,000 platforms connected by 15,100 km of pipeline, capable of producing 3 million barrels/day. To expedite oil export, the entrance to the lake was dredged beginning in 1938 and reached its present depth (14 m or 45 ft) in 1960 ...

Asphaltenes Deposition Control in Lake Maracaibo Crude Oil Production

Proceedings of SPE International Symposium on Oilfield Chemistry, 2001
Abstract Asphaltene deposition in oil production constitutes a critical and difficult to control problem, in terms of productivity and production operation costs, going from the reservoir to surface facilities. This phenomenon causes severe plugging and flow reduction due to phase changes in the crude oil through its production.

Preludes to the Entrapment of Organic Matter in the Sediments of Lake Maracaibo

Journal of Sedimentary Research, 1955
Abstract Sedimentation has continued in the Maracaibo Basin since the formation of its earliest oil-bearing strata. The present lake is reputed to be one of the most productive waters in the world. Perhaps no more favorable place can be found for examining the conditions presumed to precede the accumulation of organic matter in ...

Nutrient Loading by Precipitation in the Maracaibo Lake Basin, Venezuela

Water, Air, and Soil Pollution, 2001
Nutrient content and pH of rain samples collected at nine sites during 1988-1996 were studied to determine the amounts of N, P and S added by precipitation over Maracaibo Lake basin. The basin is a wide depression occupied by Lake Maracaibo and extensive alluvial plains and delimited by a mountainous zone of variable physiolgraphic characteristics with
