Anti-channeling cementing technology for long horizontal sections of shale gas wells

Organic compounds in produced waters from shale gas wells.

A detailed analysis is reported of the organic composition of produced water samples from typical shale gas wells in the Marcellus (PA), Eagle Ford (TX), and Barnett (NM) formations. The quality of shale gas produced (and frac flowback) waters is a current environmental concern and disposal problem for producers. Re-use of produced water for hydraulic fracturing is being encouraged; however, kn...

Experimental Investigation of Silica Fume as a Cement Extender for Liner Cementing in Iranian Oil/Gas Wells

Model of Cementing Annulus Gas Channeling Based on the Lattice Boltzmann Theory

The phenomenon of the cementing annulus micro clearance gas channeling directly influences cement job quality and oilfield production, so accurately describing the flow rule of cementing annulus micro clearance gas channeling is the core and "bottleneck" problem of controlling gas channeling effectively. From the perspective of the micro particle motion and based on the lattice Boltzmann method...

Forecasting long-term gas production from shale.

Oil and natural gas from deep shale formations are transforming the United States economy and its energy outlook. Back in 2005, the US Energy Information Administration published projections of United States natural gas supply that stressed the need to develop an import infrastructure (1): by 2025, imports would account for almost one-third of United States consumption. When we compare those fo...

Identification and ranking risks of horizontal directional drilling for oil & gas wells by using fuzzy analytic network process, a case study for Gachsaran oil field wells

Risk ranking of Horizontal Directional Drilling (HDD) for gas and oil wells is a key criterion in the project feasibility, pricing and for introducing a risk management strategy that aims to reduce the number of failures in the installation phase and its negative consequences. HDD is currently widely used in drilling wells in Iran, but research in the area of identification and risks ranking of...
