Estudio de factibilidad técnica y económica de un esquema de dos secciones tipo Slim Hole (Monobore) para la perforación en la Cuenca Amazónica

Abstract

A comparative analysis of the technical data and the drilling parameters of the wells with reduced diameters was carried out, with respect to the design of three linings (Robusto), based on drilling times, directional profile, type of drilling fluids, type of drills used, cement grout design, solids control, casing types, settlement depth and drill capacity.

The drilling phase of the SlimHole well was completed in 16.71 days, while the robust well was executed in a span of 20.48 days.

In a matter of casing, significant savings were evidenced, since the conventional design begins to run on a 13 3/8 ”surface compared to the Slim well that obtained a 9 5/8 casing, representing a saving of $ 689,419.17 equivalent to 57% compared to conventional design.

In the handling of gravel, a saving of $ 33,408.34 equivalent to 30% was observed, in a matter of sludge a saving of 22% equivalent to $ 48,814.77 and in cementing concepts a saving of $ 46,015.17 equivalent to 21% was obtained, since it was denoted that a lower environmental impact is generated with respect to waste management.

After the economic analyzes carried out, a general saving of $ 1,364,351.69 was obtained, equivalent to 33%.

Of course, this summary helps us to verify that the Slim Hole application is the most feasible design to be used in the Cuenca Oriente.
