ABOUT Tellevare

Most of the recent, substantial, growth in US oil and gas production has been due to the technical advancements of horizontal drilling and shale fracturing known collectively as US unconventional development.

To increase production, this development has required greater and greater resources be applied in terms of fuel, sand and fresh water. Our technology allows operators to obtain the same production with less resources (or greater production with the same resources) by utilizing acoustic sources at the surface to affect reservoir conditions at depth. The resulting effect lowers the amount of energy required during hydraulic stimulation to create optimal conditions for more effective completions and better wells.

Strong intellectual property foundation with a broad patent granted, comprehensive modeling completed to mitigate technical risks, a dedicated team established, and initial positive feedback received from industry stakeholders and potential customers.

CONCEPT

The proposed method involves deploying surface seismic sources to generate controlled energy during hydraulic fracturing operations.  The concept centers on creating stress waves that are orthogonal to the tilted natural fracture plane, typically oriented at 60 to 85 degrees in shale reservoirs. These waves induce dynamic stresses that promote shear slip along the fracture planes, enhancing permeability.

Additional details can be found in our white paper available below.

Drivers

Enhanced production performance:

  • Higher initial production: increase permeability with slip throughout the fracture network

  • More total recovery: increase extent of fracture network opened permanently with slip

Operational Benefits:

  • No risk to well integrity – no other equipment downhole

  • No major change in well operations

  • In resource or regulatory constrained areas, possible to decrease inputs (horsepower/fresh water/etc) and comparable results

WHITE PAPER

Unconventional shale reservoirs hold vast hydrocarbon resources, yet current recovery rates remain low, typically around 5%. This white paper explores a novel approach to enhance permeability and recoverable reserves by using surface seismic sources to generate constructive stress waves orthogonal to the tilted natural fracture plane during hydraulic fracturing. The method leverages dynamic stress interactions to induce fracture slip, increasing the near well bore fracture network.  This paper outlines the opportunity, describes the concept and method, provides a theoretical foundation using dynamic stress principles, discusses results of multidimensional finite element analysis modeling, and proposes a pilot well design to test the approach.
