Class II injection wells are widely considered to be the best method for disposal of produced salt water from the oil and gas industry. Unlike other direct disposal techniques, injection wells return the produced salt water to deep formations within the earth from which they were produced. Returning the produced water to similar formations from which it came is the most logical step in the natural process of releasing natural gas and oil from those formations.

June 18, 2019 -- What does the reconstruction of Huffman Street, just off Wells, have to do with the tunnel? The stone crushed and pulled out of the tunnel by MamaJo is the perfect fill for a road project and prevents us from spending extra to buy the fill rock. Huffman had a sewer separation project and this week; crews are reconstructing the street that was torn up for restoration. The first photo is looking west from Wells Street, and the second is looking east from Short Street.

The Tunnel Works Program represents a major part of Fort Wayne's efforts to implement the 2008 Long-Term Control Plan and associated Consent Decree with the US Environmental Protection Agency. The premier project - the deep rock tunnel - will be constructed in the bedrock deep below the city. The tunnel will collect and transport sewage from the combined sewer system to the sewage treatment plant. This sewage would otherwise discharge (overflow) into the rivers when it rains.
DEEP ROCK GALACTIC is a procedurally generated first person co-op shooter for up to 4 players, developed in Unreal Engine 4. As a team of veteran dwarven space miners, you must go on missions for your corporate overlords and venture into the deepest, most dangerous cave systems of the most hostile planet ever discovered.
Deep Rock Galactic is a first-person co-op shooter. You play as one of four Dwarves mining deep underground, where you will face off against a variety of giant creepy crawlies in procedurally generated caves. The game has been well received by fans, and was touted for its fun co-op action.
Deep rock mass possesses some unusual properties due to high earth stress, which further result in new problems that have not been well understood and explained up to date. In order to investigate the deformation mechanism, the complete deformation process of deep rock mass, with a great emphasis on local shear deformation stage, was analyzed in detail. The quasi continuous shear deformation of the deep rock mass is described by a combination of smooth functions: the averaged distribution of the original deformation field, and the local discontinuities along the slip lines. Hence, an elasto-plastic model is established for the shear deformation process, in which the rotational displacement is taken into account as well as the translational component. Numerical analysis method was developed for case study. Deformation process of a tunnel under high earth stress was investigated for verification.
With the global growth in population and subsequent growth in industrial activities, projects are shifted to an increasingly underground depth. In engineering fields, such as transportation, oil and gas extraction /storage, and mining activities, there has been a growing number of projects occurring in deep rock formations. Deep rocks are under high in situ stresses, and excavation, tunnelling, and drilling all result in unloading external disturbance during and after construction. Abnormal failures of surrounding rocks (cracking, rock burst, spalling, slabbing) are frequently being reported in deep rock engineering structures and could potentially be disastrous for the safety of underground equipment and working staff. The mechanisms of such rock instabilities are worthy of investigation.
There is increasing interest in investigating the characteristics and mechanisms of deep rock failure by means of experiments and numerical simulations. In addition, the energy storage, consumption, and distribution phenomena always exist in rock fracturing progression. Rock fracturing can be essentially regarded as a progressive failure process driven by energy. Thus, more and more researchers are paying attention to the energy evolution behaviours in rock destruction and deformation, and a more comprehensive and in-depth understanding of rock failure. Hence, it is important to better characterize various types of rocks under simulated in situ stress conditions.
This Special Issue will be focused on publishing original research articles and reviews on the latest findings concerning the mechanical characteristics of rocks under various construction and storage environments. Among the topics to be highlighted are the mechanical properties and fracture behaviour.
The long period of uncertainty had forced us in Sweden to consider alternativesfor the back end of the fuel cycle. Reprocessing of HEU was studied as wellas final disposal according to the Swedish deep rock repository method.
The Swedish system for final direct disposal of spent nuclear fuel, KBS-3[2],is based on storage of the fuel without reprocessing at large depth (around500 m) in solid crystalline rock. The same concept has also been studied insome other countries, Finland, Canada and Switzerland. The spent fuel will beplaced inside canisters in boreholes. A layer of betonite clay will isolatethe canisters from the groundwater and also in case of a mechanical failureof the canister it will form a barrier to radionuclide migration. The canisterswill be made of stainless steel and they will be clad with thick solid copperor in the AECL case titanium layer.
The R&D on deep rock repository has been going on for over a decade afterSweden abandoned the reprocessing option. As is shown in the latest annual reportfrom SKB [2] the work has covered a wide variety of technical items to solvethe safe long time disposition of radioactive waste. The repository is the finaldestination of the back end system, so first systems for transport and intermediatestorage of the fuel has been developed and built. Under development and evaluationis then the final step with encapsulation and transport to the deep rock repository,where the canisters are placed in the boreholes, which are then filled withbetonite. When all spent fuel is taken care of the whole repository is backfilledwith quartz sand and/or crushed rock.
The main effort in the development of the system has been in the geosciencefield, the structure and behaviour of the rock, coupled with the chemistry ofthe water in the fractured rock. This research has been concentrated to theÄspö Hard Rock Laboratory, which consist of a tunnel system reachingdown to 450 m. Here the hydraulic conditions for water movement is studied togetherwith the hydrogeochemistry of the water at that depth. The investigations haveresulted in mathematical models for the rock stress in a thermal-hydro-mechanicalmodel. The thermal conditions are important as the repository will gain thedecay power from the spent fuel.
All research shows that the integrity of these systems are high with an expectedlifetime of the canister of several thousands of years. The only significantmigration of the activity to the surface is considered to be through the slowmotion of the groundwater in the sparsely fractured rock.
Two fundamentally different approaches have been made for storing the spentpower reactor fuel. The first method involves encapsulation and storage underdry condition. This condition can be found in desert areas and salt mines. Theseareas have been dry for long periods even in a geological time scale and shouldthus form an excellent environment for storing the spent fuel for 100,000 yearsor more. The second method is based on storage in deep rock. In that case thespent fuel have to be caned and isolated from the ground water that penetratesthe rock. This method will be used for final direct disposition of the Swedishpower reactor spent fuel and has also been chosen in a couple of other countriesas preferred disposal method[3].
In connection with the conversation studies for the introduction of LEU fuelat the R2 reactor in 1988 there was also a study of the possibility to makea direct disposal of the aluminium clad U3Si2 fuel using the current Swedishmodel, KBS-3. The main conclusion of the study was that further research hadto be performed. The uncertainties were mainly on the corrosion rate of thecladding and subsequent leaching rate of the fission products and the transuraniumelements in case of a groundwater intrusion into the canister. Some concernwas also raised on the risk for a secondary criticality if the dissolved uraniumis concentrated in some rock cavity. The investigation stopped at that point.
The present take back of spent MTR fuel will expire in May 2006 after thatthe back end of the MTR fuel cycle has to be solved by other means. There arethree ways to go, reprocessing ( with storage of High Level Waste), final storageunder dry or deep rock conditions. In some countries the deep rock repositoryhas been developed to a probable way of storing the power reactor fuel. It wouldbe an advantage to use the same concept for MTR fuel. 041b061a72
