能源部準(zhǔn)備了這個(gè)EA來(lái)分析提議的行動(dòng)可能產(chǎn)生的環(huán)境影響。貝格提出的試驗(yàn)將建立在一個(gè)油田的地下巖土特征的歷史數(shù)據(jù)上，并將使用德克薩斯州利伯提縣南利伯提油田現(xiàn)有的基礎(chǔ)設(shè)施來(lái)支持試驗(yàn)。在現(xiàn)有的一個(gè)井位上，貝格公司將在60天內(nèi)把二氧化碳注入德克薩斯州墨西哥灣沿岸Frio組含鹽砂巖中?，F(xiàn)有的兩口井將進(jìn)行升級(jí)，對(duì)注入二氧化碳的行為進(jìn)行長(zhǎng)達(dá)1年的監(jiān)測(cè)，得到的數(shù)據(jù)將用于改進(jìn)預(yù)測(cè)鹽水地層注入二氧化碳行為的模型?，F(xiàn)場(chǎng)試驗(yàn)將有以下目標(biāo):(1)證明二氧化碳可以注入鹵水地層，而不會(huì)對(duì)健康、安全或環(huán)境造成不利影響;(2)確定注入CO2的地下位置和分布;(3)對(duì)預(yù)測(cè)CO2行為的計(jì)算機(jī)模型有一定的了解;(4)演示鹽水注入CO2的監(jiān)測(cè)方法;(5)建立用于考慮地質(zhì)封存機(jī)會(huì)的知識(shí)庫(kù)。
DOE prepared this EA to analyze the potential environmental effects that would result from the proposed action. The test proposed by BEG would build on historical data covering subsurface geotechnical characteristics for an operating oil field and would use existing infrastructure of the South Liberty oil field in Liberty County, Texas, to support the experiment. At an existing well site, BEG would inject CO2 over a time period of less than 60 days into a brine-bearing sandstone of the Frio Formation in the Gulf Coast of Texas. Two existing wells would be upgraded to monitor the behavior of the injected CO2 for up to 1 year, and the resulting data would be used to enhance models for predicting the behavior of CO2 injected into brine formations. The field test would have the following objectives: (1) demonstrate that CO2 can be injected into a brine formation without adverse health, safety, or environmental effects; (2) determine the subsurface location and distribution of the injected CO2; (3) demonstrate an understanding of computer models for predicting CO2 behavior; (4) demonstrate methods for monitoring of CO2 injected into brine formations; and (5) establish a knowledge base for use in considering geological sequestration opportunities.
