Abstract
The paper discusses TATNEFT’s experience in identifying pipelines and their sections within a water-injection system that have high hydraulic resistance based on surface facilities digital model.
Infill drilling is planned for the Bondyuzhsky oil field. Since the water injection system is closed (i.e., it is impossible to transfer produced water to TATNEFT’s adjacent fields), a digital model of water-injection surface facilities was decided to be built to determine the existing water system capacity. When building the model, actual pipeline geometry and actual characteristics of all water lines were taken into consideration. Profile of calculated wellhead pressures for water-injection wells, obtained from the model, testified that the values were overestimated compared to the actual measurements. In this context, the model was history-matched, including model sensitivity analysis by changing various parameters, specifically, choke size, pipe roughness, pipe ID, and using various types of calculation correlations, and hydrostatics and friction correction factors. Water lines matching was performed according to liquid flowing from the source to the sink. The obtained coefficients of water line diameter changing were analyzed. The results showed that in 29% of water lines, high hydraulic resistance was attributed to some technical issues. Several recommendations have been provided for the rest of the water lines on carrying out certain measures as new wells are put on stream and the amount of liquid pumped over these water lines, increases.
