请问在这个英语句子中
Experts estimate that ten times as much petroleum exists in such sources as tar sands,heavy oil,and perhaps even shale as in conventional reservoirs.
主Experts ,谓estimate,that引导宾语从句,问题就在that宾从的内部结构是怎样的呢?宾从的主谓各是什么呢?
翻译：专家们估计：在诸如油砂,重油甚至可能是页岩此类的资源中,存在着十倍于常规储库所储有的石油.
1.that所引导的宾语从句中的结构分析如下：
1）主干：主语petroleum,谓语exists,地点状语in such sources
2）ten times as much为定语,修饰主语petroleum；
3）as tar sands,heavy oil,and perhaps even shale为介宾短语做后置定语,修饰宾语sources.
such...as...意思是“像...这样的...”；
4）as in conventional reservoirs为比较状语从句,其中含有省略为：
as in conventional reservoirs
= as (petroleum exists) in conventional reservoirs
此句的as为连词,引导该比较状语从句,且和前面的ten times as...构成as...as的倍数比较句型：倍数词ten time + as + 形容词原级much + 名词petroleum...+ as.
该比较状语从句中,主语petroleum,谓语exists,都被加以省略（为避免和前面重复）,in conventional reserviors为地点状语.
