Injection wells of Tomakomai CCS demonstration project

Abstract

The 1st large scale Carbon dioxide capture and storage（CCS）demonstration in Japan aiming for the practical application of CCS technology has been conducted by Japan CCS Co., Ltd.（JCCS）, commissioned by Ministry of Economy, Trade and Industry（METI）, New Energy and Industrial Technology Development Organization（NEDO）.

The demonstration facilities including two directional injection wells to offshore reservoirs were constructed in the port area of Tomakomai City, Hokkaido from FY2012 to 2015.

The CO₂ injection at scale of 100 thousand tonnes per annum was started from April 2016 and achieved initial target of 300 thousand tonnes cumulative injection on November 22, 2019.

This paper introduces the outline of CO₂ injection wells focusing on well completion.
