NANOMITE C: a microproppant to maximize production

CARBO’s ceramic microproppant, NANOMITETM C, helps operators maintain production from their microfractures and flatten their decline curves.

NANOMITE CTM microproppant is a high quality ceramic proppant that is a fraction of the size of the smallest proppant commonly deployed and features the compressive strength and durability to maintain fracture conductivity and more space for hydrocarbon flow under closure stress. It contains a broad range of particle sizes within the 150/635 mesh (100 μm to 20 μm) range. The smallest NANOMITE particles are more than five times smaller than the smallest particles in 100 mesh frac sand. As a result, NANOMITE C provides much of the benefits of 100 mesh proppant, while propping open even the narrowest secondary fractures and microfractures.

Making the most of microfractures

null
Extremely low settling velocity and particle sizing enables propping of microfracture deep within the complex fracture network.

Microfractures created within a complex fracture network close shortly after the release of hydraulic pressure and heal sometime thereafter. Long-term production gains can be achieved by propping open microfractures in the stimulated areas so that they contribute to hydrocarbon flow, increasing production, estimated ultimate recovery and return on investment. Conventional proppant is too large to fit into these microfractures and its transport characteristics limit how far it travels into the stimulated area, limiting Propped Reservoir VolumeTM (PRVTM) and ultimately, recovery and return.

How does it work?

NANOMITE C microproppant has excellent transport characteristics and provides the strength and durability to hold open microfractures in higher closure stress conditions.

NANOMITE microproppant particles transport well in slickwater fluids, acting to increase the propped fracture height, width and length and maximizing the productive reservoir contact area in microfractures. The broad range of small particle sizes results in varied settling velocities, ensuring NANOMITE particles link the benefit in the primary fractures to the furthest tips of all created microfractures.

The average settling rate of 100 mesh sand is more than twice as fast as NANOMITE particles. The small size and enhanced transport characteristics enable the microproppant to navigate tight angles experienced in complex fracture networks, reaching otherwise untapped microfractures, contributing to increased production.
A complete increased recovery solution

NANOMITE microproppant can be used in conjunction with CARBOAIR® high-transport, ultra low-density ceramic proppant technology to create a unique solution to increase PRV and estimated ultimate recovery. CARBOAIR technology travels further into primary fractures increasing PRV as it has an Apparent Specific Gravity (ASG) of 2.0 and a settling velocity 25% slower than comparably sized sand. Additionally, the technology exceeds the conductivity, strength and durability of sand, which maximizes the production rates and recovery from the increased reservoir contact. Both technologies can be integrated as part of an overall proppant pack.
