Exploration practice of lithologic reservoirs in LS sag

LS sag is a faulted basin with a "ditch+slope+fan" deposition pattern in west slope during MYF deposit period. In view of the sedimentary background, comprehensive technology and methods are applied in LS lithologic reservoir exploration, such as high-resolution sequence stratigraphy, sedimentary facies analysis and reservoir prediction and description. Therefore a set of low sand fans favorable for oil and gas accumulation was developed, and then a new exploration field with the same deposition background and accumulation mechanism was revealed.
