Ryckman Creek will have interconnections with five interstate pipelines, all of which are connected to the Opal Hub, including Questar, Ruby and Kern River in addition to Northwest and Overthrust. Gas injections from the various pipeline interconnections will follow in phases as each interconnect becomes operational, until reservoir commissioning and pad gas injections have been completed this summer.
Instead of such result the MGCR is expanding through Poland to Moravia only in the form of the outer Rhenohercynian and Sub-Variscan molasse, overthrust on the Bruno-Vistulian foreland (Havlena, 1976; Dudek, 1980).
On the Moroccan side, for example, there are believed to be promising prospects of a deep "Rocky Mountain" type overthrust play.
* Bi-directional meter stations added to the existing Kern River, Questar and Overthrust pipeline interconnects
Despite the southern border of the Branna group is clearly bounded to an overthrust, the eastern border is not clear yet.
Customers will have access through backhaul and displacement arrangements to the Opal trading hub which will provide access to the Northwest, CIG, Overthrust and Ruby pipelines.
The Ryckman Creek Resources project will offer its customers the ability to interconnect with five interstate pipelines, including Kern River, Questar, Overthrust Pipeline, Ruby Pipeline and Northwest Pipeline, which mirrors the Opal Hub.
In places, without any justification, the boundary between the Carboniferous and the Cretaceous was interpreted as an overthrust (see Gierwielaniec and Radwanski, 1955) what in consequence became a basis for some compilations (Cech and Gawlikowska, 1999), or even of structural models of the Middle Sudetes (Cymerman, 2004).
Ryckman Creek has interconnects with Questar Gas Pipeline, Kern River Transmission and Questar Overthrust Pipeline.
The role of compaction of Miocene molasses underlying the overthrust flysch nappes should also be taken into account, since these figures range from 200-300 m to 500 m, respectively, from the early Pliocene and the early Sarmatian onwards (Oszczypko et al., 1993).
While the deflections in [z.bar] start into positive figures and thus express impulses showing subsidence in SE in respect to NW block, the general trend suggests an overthrust fault of the SE fracture block in the wall to NW.
