Solutions for production logging For horizontal wells without fracturing

For horizontal wells without fracturing

Approximately half of the horizontal wells in Russia are drilled without fracturing. As is known, to free the fluid from sand and mechanical impurities, the wellbore filter elements are used.

GEOSPLIT technology allows integrating the special polymer inserts containing quantum markers-reporters into the borehole filters. To attach the inserts to the filters, special covers are used, which are adapted to one or another filter model.

 

Each interval of horizontal well is equipped with unique signature of marker. After contact with formation fluid markers are released and carried to the surface non-stop during a number of years. Samples of formation fluid taken from wellhead are analyzed. Based on lab analysis we identify contribution of each interval to total production rate by oil, water and gas.

 

This technology is up to the highest standard of accuracy. The markers are washed out by the fluid one year plus, which enables long-term production logging without well intervention.
