... streams. In the oil plays, the Delaware had the lowest decay, with 17% for proppant and 12% for fluid. By contrast, the Bakken had 54% decay for proppant and 37% for fluid. The gas plays and some gas production streams of oil plays showed increasing impact through time of completions design...

... Background The pioneering shale gas plays -- the Barnett and Fayetteville -- have become increasingly mature and today are several years past their prime. From a peak of 5.7 Bcfd in 2012, the Barnett has declined to 3.5 Bcfd of natural gas production (wet) in early 2017. Similarly, natural gas...

... shale gas plays over the 2008–2015 period shows that the aggregate production of the three major gas plays (Barnett, Haynesville and Marcellus) has not stopped increasing. Over the past two years, and with 4 times less operating rigs, this growth has been even more significant than that observed before...

...). In this section we use two examples from North America to show how the same simulation codes, with some modifications, can be used to make useful predictions in shale plays. In the first example we show how a 28-layer 3D petroleum system model of the Haynesville shale gas play was able to provide a spatial...
