STEP-PLEX™ diverting agents are unique multi-modal diverting technologies tested in dynamic conditions that combine a number of environmentally friendly, slow degrading solids used as temporary blocking agents. The systems are excellent blocking agents for fluid loss prevention, bridging, loss circulation prevention, conductivity improvement and fracture fluid diverting. STEP-PLEX™ is uniquely customized depending on the desired application, time and temperature. The rate of degradation can be controlled from hours to weeks depending on the product, particulate size and down-hole conditions.

Conventional methods of fracturing rely on rock stresses to indicate where the rock breaks. This can lead to over stimulation of a single fracture and poor stimulated rock volume. Diverting agents are used to isolate dominate flow areas of the wellbore and redirect the proppant and fracture fluids to new sections of the reservoir. This method of fracturing increases fracture complexity resulting in improved production performance.
In addition to the development of new wells, many producers have found value in the remediation and revitalization of existing wells. Refracturing technology has changed significantly with the trend moving towards more proppant and tighter fracture spacing to maximize stimulated rock volume, estimated ultimate recovery, and improve project economics.
Based on a thorough investigation of the completion history, reservoir characteristics and field samples, STEP’s expert engineering team can customize a fracturing treatment schedule to increase stimulated rock volume with far-field or near wellbore diverting material.
