QX1 well is the first horizontal well of unconventional dense sand oil reservoir which is explored to ensure oil productivity of 40 million ton every year in Daqing Oil Field.
Harding Shelton provide fracture design and technology service for QX1 well which includes drilling design, coring, core analysis, log interpretation, horizontal section optimization proposal, comprehensive evaluation of reservoir, fracture design, construction preparation, construction and flowback guidance, post-frac analysis and fracture summary.
QX1 well has the largest fracture of horizontal well of unconventional dense sand oil reservoir both in Daqing oilfield and China. Through fracture technology guided by Harding Shelton, the oil productivity increases by 20 times compared with that of other vertical wells, and more than 4 times compared to that of conventional low permeability horizontal well. The truth shows that stimulated reservoir volume (SRV) fracture technology of Harding Shelton can realize the effective development of tight unconventional reservoir.
