... Abstract The objective of this paper is to present the improvement in zonal isolation and cement sheath properties using foam cement in heavy oil Chichimene Field in Colombia. Achieving complete zonal isolation in the pay zone have become a major challenge in these fields, recently, given...

... massification in place supported on required results. Rotating cement heads have been widely used in a variety of fields within Colombia. At Llanos basin, they have been used to improve bond results in front of very washed out sections near the casing shoe; at superior and mid valley basins, they have allowed...

... Abstract The geological evolution of the northern region of Colombia has resulted in lateral/oblique compressional stresses leading to the development of tilted faulted blocks and associated subsidence, followed by intense folding/uplift that has impacted the stress regime and the pore pressure...

... Abstract The behavior of two Castor oil based muds (OBM) prepared with additives marketed in Colombia is observed, the concentrations of the additives are the same for both fluids with the difference that one has as rheological modifier a polar activator and the other uses lime. These ones...

Horizontal well technology was used to drill through unconsolidated sandstones with an active and strong aquifer, under primary heavy oil depletion with an oil gravity...

... Abstract In Colombia, relative permeability modifiers (RPMs) are often included in fracturing fluids to limit water production in wet producers. However, the results of their application are mixed. Since many reservoirs have an oil/water contact, or are close to an oil/water contact with poorly...
