Main methods of casing-head gas utilization in oil-gas condensate fields development was examined. It s shown that in the difficult of access remote oil producing regions it is possible to pump casing-head gas in a porous stratums for the purpose of temporary storing and subsequent using as a first stage of the casing-head gas utilization. Outlined proper porous stratums for the creation of temporary underground casing-head gas storages. Complex of technologies, which was developed and approved in underground gas storage is examined. It is shown application of these technologies in rational oil-gas condensate fields mining and temporary storing of casing-head gas.
