Introduction

An effective gelling agent for gelled acid systems. When high concentrations of this cationic polyacrylamide are used with acid, the fluid exhibits viscosity. If we need sufficient viscosity to divert the acid to untreated zones, crosslinking of gelling agent with trivalent metal crosslinkers such as iron is necessary. The viscosity of gelling agent developed in acids will lubricate the interface between tubular and pumping fluids and change the flowing status of the fluids, which leads to lower friction pressure.

Physical Properties and Hazards
Chemical Properties and Application

Gelling agent is a cationic polyacrylamide emulsion in oil that is used in Delayed Gelled Acid formulations. It can be dispersed in acids continuously or batch mixed. Gelling agent is compatible with most acid additives including surfactant, corrosion inhibitor, and iron control additives. Typically the gelling agent concentration used for gelling acids ranges from 20 to 30 gpt, and is dependent on the well bottom hole temperature. Formation damage caused by gelling agent is generally minimal because of the de-crosslinker used in the formulation to remove iron when the pH goes above 4 during acid spending.
