Oil and gas exploration in Songliao basin has gone through three stages

i.e.

structural

non-structural

and current deep reservoir exploration.During the practices if deep gas reservoir exploration

discoveries have been achieved in well Xushen-1

Changshen-1 and Yaoshen-1

and a gas industry base begun to take shape in the basin.Exploration activities in the basin prove that for obtaining breakthrough in deep gas exploration

deeper geologic understanding and creative exploration idea are the basis

application of the advanced engineering technique is the key

and consistency and cooperation in exploration and enforcement in management are the guarantee.Generally speaking

Songliao basin remains largely unexplored and there are plenty of opportunities for further exploration activities.Three direction of explorations are volcanic rocks

clastic rocks

and the Carboniferous-Permian marine facies.It is safe to say that more discoveries of larger scale will be achieved through strengthening exploration in these three directions.
