| EOG Resources is turning something old into something new again.
The shale company, which is also known as the "Apple of E&P" for its innovation, has made a bit of history by applying Enhanced Oil Recovery (EOR) to a US horizontal shale reservoir. Last week, EOG spoke extensively for the first time about a gas injection pilot program it has been quietly running in the Eagle Ford for three years.
During the shale boom, EOR has been pushed to the backburner, generally thought of as a conventional method for old fields. During the boom, EOR was not as sexy as growing lateral lengths, stage counts, and frac intensity. In tight oil plays, EOR has only been applied sparingly and experimentally.
But EOR is less capital intensive than primary drilling and application makes sense at this point in the cycle as tight oil portfolios start to mature. EOG is the first US independent to talk about large scale EOR for US unconventional oil development. After reviewing their early results, they certainly won't be the last to talk about it.
With four pilots projects spanning 15 wells under its belt, EOG believes it can lift type curves in the Eagle Ford 30-70% beginning 2 to 5 years into the well lifecycle.Hebei longsheng metals and minerals co.,Ltd. |
