High-Temperature Temporary Diverting Agent TDA-200
Product introduction
Racturing and acidizing, as the key technologies for conventional oilfield stimulation and for the commercial development of unconventional oil and gas resources, are of significant interest to oil companies and governments. However, conventional fracturing and acidizing treatment cannot meet the requirements of diverting re-fracturing for old wells and increasing SRV for the development of unconventional oil and gas resources. In consequence, temporary plugging and diverting stimulation technology (TPDST) have been developed
Designed to help optimally place the acid treatment along the wellbore, This TDA-200 is safely cleaned up following the treatment, enabling enhanced productivity throughout the treated interval.
In the oil and gas industry, hydraulic fracturing involves the injection of a high-pressure fluid mixture into a wellbore to create fractures in the rock formation, facilitating the extraction of oil and gas. The effectiveness of this process hinges on ensuring complete stimulation of all perforation clusters and targeted zones within the reservoir. TDA-200 plays a pivotal role in providing temporary diversion to optimize the efficiency of the hydraulic fracturing process.
Specifically engineered for high-temperature hydraulic fracturing, re-fracturing, acid fracturing, and matrix acidizing applications, TDA-200 is designed to withstand the extreme downhole temperatures often encountered in these operations. It offers both near-wellbore and far-field diversion in sandstone and carbonate formations, catering to a diverse range of geological settings.
One of the key attributes of TDA-200 is its versatility in terms of carrier fluids. It can be seamlessly pumped in a variety of carrier fluids such as slick water, gelled acid, linear gels, and viscoelastic surfactants, providing flexibility in application and logistics. This adaptability allows for simplified integration into different fracturing fluid systems, enhancing operational efficiency.
The composition of TDA-200 is carefully engineered to achieve optimal diversion performance. It utilizes a tri-model particle size distribution, comprising a mixture of large robust particles and smaller particles. This design enables the diverting agent to bridge across perforations, wormholes, and fractures, effectively diverting the fracturing fluid while minimizing the permeability of the diverter pack. Additionally, a smaller bi-modal distribution of TDA-200 can be employed to provide far-field diversion, ensuring comprehensive coverage of the reservoir.
Moreover, TDA-200 is formulated to be fully degradable and soluble in both hydrocarbons and water-based fluids. This characteristic ensures that the diverting agent can be effectively deployed without causing long-term environmental impact. The rate of dissolution is carefully controlled to allow for proper mixing and pumping without degradation, maintaining the integrity and effectiveness of the TDA-200 throughout the operation.
In conclusion, Temporary Diverting Agent TDA-200 is a valuable asset in the oil and gas industry, contributing to enhanced reservoir stimulation and improved production outcomes. Its ability to provide temporary diversion, withstand high-temperature conditions, and adapt to various carrier fluids makes it an essential component in optimizing the efficiency and effectiveness of hydraulic fracturing and well stimulation operations.
