A rigless chemical frac-hit remediation process was designed to address the damage mechanisms of capillary phase trapping, reduced hydrocarbon relative permeability, paraffin deposition, and minor scale deposition.

The US producer also closed its acquisition of assets in the Permian through a deal with Primexx.

Lagoon becomes a multibasin player in water management while WES locks down assets that could drive future deals.

Canadian midstream giant adds key US oil export capacity via private-equity exit.

The authors write that cyclic gas injection enhanced oil recovery for Eagle Ford volatile oil can yield substantial increases in estimated ultimate recovery.

The deal follows investor pressure shared across the US shale sector to reduce leverage and capital outflows.

Though shelved by low oil prices, the plan to execute the largest enhanced oil recovery program of its kind offers insights into what it may take for the shale sector to escape pilot mode and scale up gas huff ’n’ puff operations.

The complete paper presents a large-scale work flow designed to take a vast amount of data into consideration. The work flow can be scaled for projects of any size, depending on the data available.

Production data from the oldest horizontal wells in the three largest oil plays in the US show that annual decline rates remain relatively high for a long period of time. This challenges assumptions held about production after 5 years and directly affects reserve and ultimate recovery estimates.

According to a new report from the EIA, the volume of natural gas reported as flared reached its highest average annual level in 2018, 1.28 Bcf/D. With production soaring in the Bakken, Permian, and Eagle Ford plays, North Dakota and Texas accounted for more than 80% of that total.
