Análisis comparativo entre las prácticas operacionales históricas y las actuales en la perforación de la sección 12 ¼ en los pozos del bloque 61

Abstract

The Intermediate Section of 12 ¼" is the section that presents major inconveniences during drilling due to: complicated trips, poor cleaning of the hole, intercalation of different lithologies, presence of conglomerates and directional difficulties all these characteristics have made it a challenge during the drilling to this day. It is for this reason that this thesis needs to perform the comparative analysis of drilling times in the Intermediate Section of 12 ¼" of the selected wells of Block 61, classified into two groups: Group 1 (2013 - 2015) and the Group 2 (2016 - 2017). The wells were organized according to criteria such as: directional profile (wells type "S", "J HD" and "J Modified"), time and zones, where it was determined that drilling times are reduced in Group 2. For which a database was made and tables were designed, comparative matrices of: drilling fluid parameters, drilling parameters, bits, casing run, cementation and drilling times. Subsequently, practices, processes and technology were identified that have been applied over time to reduce drilling times in the Intermediate Section of 12 ¼". Finally, the operational performance in the wells of Groups 1 and 2 of Block 61 was analyzed.
