Comparison of Geomechanical Models obtained from DInSAR with existing model generated from well logs for the Lower Lagunillas-07 (LGINF-07) Reservoir in Lake Maracaibo, Venezuela
Keywords:
Compaction, DInSAR, geomechanical characterization, geopressured, subsidence
Abstract
The LGINF-07 reservoir, located in the Lagunillas Lago field within the Lake Maracaibo basin, spans 200,000 m² and contains 18° API crude oil, accounting for 73% of the original oil in place (OOIP). Production-induced rock compaction has caused progressive surface subsidence. To enhance monitoring, the DInSAR technique was applied to all oil platforms, enabling comparisons between subsidence and production values in the most affected areas. The study aimed to compare the 1D geomechanical model obtained through DInSAR with the existing model based on well logs, incorporating recent petrophysical and sonic data as well as core sample characterization. Results revealed a normal stress regime (σV > σH > σh) and demonstrated that the updated model is more accurate than the previous correlation-based model. The integration of DInSAR with geomechanical parameters improved the identification of critical subsidence areas, highlighting AGUA-230, AGUA-241, and AGUA-242 as the most affected. This updated model enhances operational management and strategic decision-making, helping to mitigate the impact of subsidence on critical infrastructure and improving production efficiency
