... Different mechanisms, such as multi-ion exchange ( Lager A, Webb K 2007 ) and double-layer effects ( Ligthelm et al. 2009 ), are proposed to explain the mechanism of oil recovery by smart and low water injection. hybrid methods are recently studied and proposed to improve the performance of smart...

During hydraulic fracturing with slick water a consistent rise in the injection pressure is recorded whereas sudden fluctuations...

.... In the 2-way fully coupled dynamic-geomechanics modelling, geomechanical analysis is conducted to evaluate the field behaviour including reservoir compaction, seabed subsidence, fault stability and caprock integrity. With the change in the pressure and temperature, either by production or injection...

... and injection facilities. To maximize economies of scale, new CCS systems are being developed as industrial ‘clusters’ or ‘hubs’ ( Brownsort et al., 2016 ; Kahlke et al., 2010 ; Brunsvold et al., 2011 ) where emitters of diverse industries (cement, fertilizer, steel, refinery, power, H 2 production, etc...

... sequestration being implemented. The industry is well-versed in gas injection in reservoir formation for pressure maintenance and improving oil recovery. However, there are striking differences between the injection of CO 2 into depleted hydrocarbon reservoirs and the engineered storage of CO 2...

... Abstract Most of the fields in Ecuador are considered "mature." Water injection is a well-known solution for mature fields. Water injection projects require a source of clean water. Traditionally, minimum specifications are achieved by surface treatment facilities. However, in the Ecuadorian...

..., and consequently fluctuation of injection pressures is anticipated. Given this, it is required to ensure that fluids flowing via the surface workflow from the pumping set to the wellhead are always pure liquid. In the event of accidents, contingency measures shall be taken correspondingly, depending...

... Under the limitation of platform life, in order to exploit as much oil as possible in the limited platform life, we propose an efficient development model of offshore oil field, which is "early water injection, water injection is polymer injection". Three oil fields were selected for polymer...

... the injectivity of steam ( Buckles 1979 , Vittoratos 1986 ). During CSS, high temperature and high pressure steam in the range of 10 to 12 MPa is injected into the reservoir which is typically higher than the reservoir fracture pressure. Such high injection pressure of steam forms fractures in the reservoir...
