Injection of treated coal seam gas co-produced water into deep Precipice aquifer in Surat Basin, Queensland, Australia.

This collection represents the hydrochemical data collected for samples from a field-scale aquifer injection trial and a number of laboratory sorption experiments conducted with aquifer sediments. The field trial was carried out at a site located in the Surat basin, Queensland by injecting treated coal seam gas (CSG) co-produced water into deep Precipice Sandstone formation (>1,300 mBGS). The laboratory experiments were conducted to determine the arsenic sorption characteristic of the sediment under varying geochemical conditions.

本数据集收录了野外规模含水层注入试验的样品水化学数据，以及以含水层沉积物为对象开展的多组实验室吸附实验数据。本次野外试验位于昆士兰州苏拉特盆地某场地，将经过处理的煤层气（CSG）采出伴生水注入地下深度超过1300米的悬崖砂岩地层（>1,300 mBGS）中。本次实验室实验旨在探究不同地球化学条件下沉积物对砷的吸附特性。
