Novel Fracturing Technique Inhibits Post-Fracturing Water Production

Hydraulic fracturing has been extremely successful in the western desert of Egypt, with approximately 85% of the production<br>resulting from the use of this stimulation technique. However, in many cases the proximity of producing zones to underlying<br>(or overlying) water zones can be a deterrent to fracturing. In the absence of geological barriers, the fracture height can grow<br>uncontrolled during a fracturing treatment into the water-bearing interval and cause unwanted water production. Excessive<br>water production can be detrimental to the economics of a well. By shortening the well’s production life and increasing<br>disposal and lifting costs, excessive water production can be extremely detrimental in marginal fields.
