Production logging is a critical component of developing optimum modeling, completion and stimulation practices. When measuring downhole flowing production profiles, identifying zonal contributions of water, oil and gas are critical to validate and calibrate reservoir modeling and completion and stimulation practices. It is important to remember zonal production rates should be consistent with predictions from reservoir models and will verify the effectiveness of the stimulation treatments.
Production logging tools are run down the wellbore and record the behavior and nature of fluids inside the well during production or injection. Once the logs are prepared, dynamic analysis of well performance is done at different production zones. The logs are also used to monitor the results when well stimulation is performed. Production Logs are produced for all types of wells (vertical, deviated or horizontal). The production logging tools used are modular and can be combined with array of sensors that logs the production data. These tools provide real-time production data and generate logs at continuous intervals during the production. Some of the tools used include:
Quartz Pressure Gauge
Pressure gauges is tool used to measure downhole pressure and temperature. This gauges can be used for short or long period surveillance. Quartz technology provides superior performance in applications where data quality is critical.The quartz trans-ducer provides better long term stability and greater accuracy than piezo-resistive transducers.
