Program for quality management of well flow measurements as a way to improve data quality, optimize labor costs and HTR-reserves compliance

Flow rate is one of the key parameters used by the company’s services. The measuring equipment is integrated with automated process control systems in data transmission. However, due to the growing well stock and the increasing number of measurements (including measurements for HTR-reserves’ (hard-to-recover reserves) wells), the process of analyzing and validating lcmeasurements began to require significant human resource contribution. The well metering quality management tool was developed to reduce the time for data processing and to strengthen control.

The aim of this work is to describe the practical experience of implementation and using a special software package for quality management of well flow measurements.

Materials and methods. The well flow measurement quality management tool is an intermediate link between a well and a commercial hydrocarbon accounting system. It performs the function of filtering the data with automatic verification of its parameters. The tool for monitoring well metering allows us to integrate measurement data, laboratory data, well operation parameters and equipment into one system.

Results. Implemented algorithms for calculations and automatic validation of measurements as well as system’s business rules have allowed to reduce time spent on validating flow rates and watercut by 70 %, and to eliminate negative human impact. The tool for data quality management and the special module have significantly reduced the non-production time of analytics (for searching, collecting, recording and analyzing the parameters of the well and the equipment), strengthening control over the wells metering.

Conclusions. All the completed improvements made it possible to use the incoming data as efficiently as possible, to quickly respond to changing operating modes of wells.
