Equilibrium cannot be maintained because of differences in the transport rates for water and gas in shale gas reservoirs, so the standard equations must be modified. (eponline.com)
It is challenging to apply water flooding in tight oil reservoir due to low injectivity and poor sweep efficiency. (nature.com)
Here, we quantitatively investigate and provide preventions for the fracturing water pollution in the underground gas reservoir. (mdpi.com)
We study the effects of fracturing water pollution on reservoir permeability with core experiments. (mdpi.com)
The water passes through the hot, fractured rock and is collected and drawn up through another well on the side of the fractured area. (freethink.com)
Primary carrier fluid is the base fluid, such as water, into which chemical additives are mixed to form the hydraulic fracturing fluid. (watershedcouncil.org)
As much as 80% of the water that's used in conventional methods stays in the reservoir and most of the water that does flow back has to be disposed of safely. (energyindepth.org)
165 Water, and air or foam are pumped into the well to increase the pressure in the reservoir. (energyjustice.net)
Although most of these structures are saline water-bearing, eight gas fields with BSF reservoirs have been discovered to date. (earthdoc.org)

A "conventional" gas reservoir is produced from sands and carbonates (such as limestone). (teco-inc.com)

Their approach could characterize fracture parameters. (hindawi.com)

We deeply understand the ever-changing landscape of hydraulic fracturing and the corresponding need for fluid handling systems to evolve in step. (hydrotechtesting.com)

A mechanical earth model (MEM) is built from seismic attribute and drilling and diagnostic fracture injection test results. (hindawi.com)
Question: If the science of predicting the risks and mitigation of induced seismicity, figuratively speaking, was a glass of hydraulic fracturing injection fluid, would it be half full or half empty? (aapg.org)

Additional information, specifically regarding fractures, is crucial to unlocking the productivity of unconventional shale plays, such as the Bakken. (worldoil.com)
Coverage includes US, Canada and International Plays, from the Vaca Muerta In A new estimate from the U.S. Geological Survey finds that Colorado could actually hold 40 times more natural gas than previously expected. (tati.hu)
Overall Goal The overall goal of our study is to provide reservoir-specific geological and engineering analyses of the (1) emerging Green River Formation (GRF) tight oil plays (such as the Uteland Butte member, Black Shale facies, etc. (tati.hu)
Some of the algorithms and methods that he has pioneered have been applied for early appraisal of ultra-deepwater plays in the Gulf of Mexico and for characterizing natural fracture networks in conventional as well as unconventional reservoirs. (psu.edu)

Researchers studying artificial nanomaterials have developed new gas transport equations that need to be adapted to the complicated pore spaces that describe shale gas reservoirs. (eponline.com)
In the conventional reservoir, the gas is in interconnected pore spaces, much like a kitchen sponge, that allow easier flow to a well. (teco-inc.com)

The presence of natural gas fields demonstrates the capability of the various top seals to effectively seal significant gas accumulations over geological time-scales. (earthdoc.org)

In shale gas reservoirs, significant amounts of natural gas exist as conventional "free" gas in porous spaces as well as "adsorbed" gas on shale matrix. (metu.edu.tr)

These fractures can provide additional pathways for the gas that is locked away in the shale, once the hydraulic fracturing operation takes place. (teco-inc.com)

A workflow for co-processing and methods of analyzing reservoir changes using legacy surveys is developed. (mines.edu)
One of the widely used storage methods is underground natural gas storage (UGS) facilities that have been used since 1915. (metu.edu.tr)
The goal of this project is to develop a robust reservoir model to test possible oil recovery methods that do not use steam or a liquid capable of freezing for the Umiat and similar frozen reservoirs. (doe.gov)

The propagation mechanisms of hydraulic fractures in fracture-cavity reservoirs are different from conventional reservoirs on account of the stress concentration surrounding cavities. (techscience.com)
In this paper, we develop a fully coupled numerical model using the extended finite element method (XFEM) to investigate the behaviors and propagation mechanisms of hydraulic fractures in fracture-cavity reservoirs. (techscience.com)

LPG-an abundant by-product of the natural gas industry-is stored at ambient temperature. (energyindepth.org)

Unlike other fossil fuels, natural gas cannot be loaded on a ship or train for transportation from its source to the end user. (ukdiss.com)

It is located in a depth of 3000 m and lower, and the reservoirs keep large amounts of methane. (univie.ac.at)

It works best in places like California or Iceland, where there's a lot of moving tectonic plates or volcanic activity to create these reservoirs. (freethink.com)

A non-technical description of hydraulic fracturing helps explain the source of the recent productivity gains. (perc.org)

In this research, an integrated workflow from geomechanics to reservoir simulation is suggested to accurately estimate performances of a shale gas reservoir. (hindawi.com)
In the last decade, there have been a lot of researches to predict performances of shale gas reservoirs using a numerical simulation. (hindawi.com)
One method is to use only a reservoir simulation model, and hydraulic fracture (HF) parameters such as fracture height and half-length are considered uncertain parameters. (hindawi.com)
The other method is to integrate a HF simulation and the reservoir simulation model. (hindawi.com)
Simulation results show that a higher lateral stress coefficient can enhance the influence of the natural cavity, causing a more curved fracture path. (techscience.com)

Despite these challenges, the tight gas market continues to grow, driven by advancements in drilling technology and increasing demand for natural gas. (futuremarketanalytics.com)
