What is a multifunctional proppant?

With the continuous development of hydraulic fracturing technology, researchers have designed and prepared a series of multifunctional proppants, such as surface-modified proppants, self-suspending proppants, and slow-release proppants, to effectively address issues like water production, sand production, and scaling in reservoirs.

How can Ceramic Proppants improve thermal conductivity & adhesion performance?

Additionally, Xu et al. (50) developed a novel proppant by coating ceramic proppants with epoxy resin and graphite, reducing settling time by up to 46%, increasing thermal conductivity by 245%, and improving adhesion performance by 47.9%.

Are neutral-wet Ceramic Proppants better than unmodified proppant?

Neutral-wet proppants have also shown promising results. Low-density ceramic proppants with neutral-wet modification exhibit better conductivity under high closure pressure compared to unmodified proppants, with significantly reduced crushing rates. This effectively increases the flowback speed and reduces the water content.

What is the literature survey on multifunctional proppants?

3. Challenges, Gaps, and Perspectives The literature survey on multifunctional proppants includes 132 relevant articles. Among these, research on tracer proppants constitutes the largest portion at 21.2%. This is followed by surface-modified proppants, which account for 15.9%, and sand control and flowback prevention proppants at 13.6%.

Which proppants are most commonly used?

Among these, research on tracer proppants constitutes the largest portion at 21.2%. This is followed by surface-modified proppants, which account for 15.9%, and sand control and flowback prevention proppants at 13.6%. Both self-suspending and sustained-release proppants represent 12.9% each.

Can multifunctional proppants reduce the volume of slickwater injected?

As a solution, researchers have developed multifunctional proppants that alter the surface properties of proppants to enhance bubble adsorption, thereby reducing density and achieving suspension. Field experiments have shown that these proppants can effectively reduce the volume of slickwater injected.
