The Sabriyah Field in Kuwait contains the limestone Tuba formation that is both naturally fractured and vuggy in nature, with heterogeneous rock properties and bottomhole static temperatures around 170°F/76°C. Overcoming excess fluid leak-off to achieve deeply penetrating fractures is critical to enhance production when acid fracturing in such formations. In addition, the operator wanted to treat multiple perforated intervals in a 65-ft single stage of a vertical well. Because fluid travels along the path of least resistance, acid coverage across perforated intervals can be inconsistent, leaving some of the reservoir untreated.

To overcome these challenges, Baker Hughes, a GE company (BHGE), recommended the REAL Acid Divert™ temporary diverting agent, which is a proprietary diverter formulated for nearwellbore and far-field solid particulate temporary diversions. The near-wellbore formulation is a tri-modal particulate distribution with large robust particles designed to withstand surface equipment and bridge across perforations and near-wellbore fracture widths, as well as smaller particles that help to minimize the permeability of the diverter pack. The far-field formulation, which consists of a smaller multi-modal particulate distribution, is effective in narrower fractures and wormholes, deepening penetration of the stimulation fluid along the entire fracture length. Both diverting formulations are fully degradable, and neither one inhibits the permeability of the created fracture or the perforated interval when production starts.
