GASFRAC have successfully completed a Hybrid LPG fracturing treatment for Terrace Energy in the Eagle Ford formation in Maverick County.
"This successful use of hydrocarbon-based fracturing fluids represents a significant advancement in the development of the Eagle Ford Shale in the "black oil" window, which is defined by low gas-oil ratios found in the northern extension of the formation. Previous attempts, by other industry participants to develop commercial production in the black oil window of the Eagle Ford Shale, were made using high volume water-based fracturing fluids. This technique has generally not been commercially successful, despite the formation's rock properties and hydrocarbon content, because the formation's shallow depth and lower reservoir pressure make it difficult to recover and unload the large volumes of water used. Testing results to date indicate excellent formation productivity and there is no evidence that water resides within the formation."
