What is it about?
The reservoir was usually treated as horizontal distribution, whereas the sloping reservoir was not considered. In this study, based on currently available geological data from field measurements in Shenhu area of the South China Sea, the effects of formation dip on gas production were investigated through depressurization using a horizontal well.

Why is it important?
The sloping formation is not conducive to free methane gas recovery, which results in more dissolved methane produced at the horizontal well.
Perspectives
The development of the favorable well completion method to prevent water production is significantly important for realizing large scale hydrate exploitation in the future.
