Forum: Just How Safe Is ‘Fracking’ of Natural Gas? - Yale E360

Put simply, ,shale gas, — a form of natural ,gas, — is a fossil fuel, and fossil fuels are dirty fuels. This is not to say that there is no role for ,shale gas,. There is. But that role is far more limited than the hype suggests. Used, for example, to power existing, underutilized ,gas,-fired power plants as a way to immediately supplant aging, highly destructive coal-fired power plants in the near term, ,shale gas, makes some sense.

natural gas from within the dense shale can flow into the well and be collected for processing. As well as the valuable natural gas, fluids from the process also flow back up the well to the surface due to the pressure gradient. These can be from the shale formation itself or leftover fracturing fluids from the initial

Using a high-pressure phase equilibrium apparatus and vibrating-tube densimeter, phase transition pressures of CO2 (1) + acetic acid (2) binary systems with x2 = 0.000, 0.107, 0.163, 0.222, and 1.000 were measured under temperatures from 308.15 to 338.15 K. Besides, the densities at the same composition and temperature under pressure from 15 to 45 MPa were also detected, and the volumes of ...

Recovering Valuable Byproducts from Oil and Gas Wastes
Recovering Valuable Byproducts from Oil and Gas Wastes

The first step in treating drilling ,fluids, at the rig is to run the fluid recovered from the hole through a vibrating screen known as a shaker screen or ,shale, shaker. This screen separates most drill cuttings, which are then stored for disposal or to be treated for reuse. Photograph 1 – Backyard Drill Rig

CHAPTER 1 Introduction and Overview: the Role of Shale Gas ...

As noted, horizontal drilling and hydraulic ,fracturing, are the two technologies that together have the potential to unlock the tighter ,shale gas, formations. Hydraulic ,fracturing, (also known as “fracking”) is a well-stimulation technique which consists of pumping a fluid and a propping agent (“proppant”), such as sand, down the wellbore under pressure to create fissures in the hydrocarbon-bearing rock.
