There are several techniques to optimize production and avoid reservoir damage caused in the different phases of the development of oil wells (perforation, completion, production and workover), ranging from the control of water, chemical stimulation, mechanical stimulation, fracture, re-perforation of producing areas, etc.

In the case of phase completion, holes are perforated through canyons to connect the reservoir with the wellbore and get well production, however this technique, often not doing its job, because it does not exceed the damaged area, produced in the drilling phase, when applying sludge systems or the primary cementing is performed, brings further cause damage to the compacted in the vicinity of each hole area.

Abrasive perforation technique was used in 1958 approximately and thanks technological advances in the field of materials and chemistry, has had substantial improvements, has created new expectations for avoid formation damage and hence an improvement in the production of oil producing wells.

In order to analyze and predict the well Productivity, it is necessary to perform an appropriate perforating analysis; this can be achieved integrating Petrophysics, Geomechanics, Reservoir and Production Domains. For an advanced Perforating design a clear understanding of rock characteristic, depth of damaged zone and reservoir behavior is used in the Perforating simulation. This enhances the right selection of charges and ensures they will overpass the altered zone.

Abrasive perforation technique has been used to optimize production from oil wells and avoid the reservoir damage to the drilling and completion phase, replacing conventional techniques shooting. This methodology was implemented in Coca Field. This helped to optimize and predict the productivity of the wells.
