UZV-180  Diverting Agent

Product introduction

The common acidification effect is not ideal due to the high heterogeneity of the reservoir. In order to solve this problem, we synthesized the diverting agent UZV-180 for acidizing fluids. It will turn the spent acid into the gel-like liquid by increasing its viscosity, forcing the subsequent fresh acidizing fluids to turn from a relatively high permeability zone to the low permeability zone. The gel-like liquid will automatically break thoroughly once meet the hydrocarbons then return to the ground. Finally, achieve the purpose of uniform acidification.

Application

The recommended dosage of UZV-180 is 3.0~8.0% (30~80 kg/m3). Adding the recommended dosage evenly into acid circulating in the preparation acid process. This product has good compatibility with a variety of other additives, no special requirements on the order of addition.

Secondary additives such as corrosion and asphaltene inhibitors should be co-injected with the VES containing fluid to protect the well and mitigate secondary issues which can occur as a result of reservoir acidizing. Performance testing of the fully formulated fluid should be performed to ensure no negative impact on the acid-depletion viscosification mechanism.
