Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Carbon dioxide has been proved to be an effect agent to enhance oil recovery. CO2 huff and puff is a very appealing technique in tight fields where water flooding is difficult. Two horizontal wells in a tight field in Northeast China received carbon dioxide injection. One well achieved good results, but the other well failed to show positive response. Possible causes of failure are analyzed, and suggestions are made for future projects. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
