... on tight gas formations. Over 50% of the patents filed have been made through the Patent Cooperation Treaty (PCT) route indicating the assignees' intent to practice these technologies globally. Schlumberger is a key player in the tight gas recovery area focusing on hydraulic fracturing and slick water...

... Abstract Unconventional reservoir has become the hotspot of development in petroleum industry. In shale reservoir, some fracture is only propped by a monolayer 100mesh proppant. Fracture width is very small and under the condition of low rock hardness and high effective closure stress...

... the impedance value in any location using the electrical circuit analysis approach. We observe a reasonably accurate analogy between these two methods. Fracture and Wellbore Impedance Analysis Figure 4 shows the schematic of a transmission line. Figure4.a shows a transmission line, often...

... Abstract A hydraulic fracturing stimulation campaign has been successfully conducted in Rimau block. The stimulation was applied in tight KTLS sandstone formation with permeability within the range of 5-10 mD and also conducted in medium permeability multilayer LTAF sandstone (>10 mD...

... Abstract Hydraulic fracturing stimulation is one of the key technologies for shale gas development. The recent advances in micro-seismic data acquisition and processing suggest that hydraulic fracturing stimulation has often resulted in complex fracture network due to the pre-existing natural...

... Abstract The application of horizontal well drilling and multi-stage fracturing has become a norm in the industry to develop unconventional resources from ultra-tight formations. A complex fracture network generated in the presence of stress isotropy and pre-existing natural fractures immensely...

... Abstract Advanced hydraulic fracturing has become a complex and investment intensive operation; hence, predicting its performance has become more important than ever. Robust prediction of production profiles for hydraulically fractured wells is imperative for optimizing the fracture scheme...

... Second, by comparing the measured post-treatment J fD to the theoretical J fD max ( N p ) for that treatment, it is possible to assess the overall effectiveness of the fracture simulation, materials selection and fracturing operations. This will be discussed in greater detail below...

... from 8000 bbls to 11,500 bbls depending on the theoretical maximum productivity of each well when pumped off. The Spring Creek field produces out of the fractured Tensleep sandstone, and the fractured Phosphoria carbonate. The main drive mechanism is bottom water, but reinjection of produced water...

... Abstract From decades ago till now, most oil wells in Iran produce using their natural flow potential and they don’t need to be fractured. This is why few cases of hydraulic fracturing are recorded in the history of Iranian oil industry. This paper reviews the three cases of acid fracturing...

... Abstract In the western desert region of Egypt, previous propped multiple-fracture treatments were performed using conventional methods (i.e., perforate, frac, set mechanical/zone isolation, and repeat cycle). Although the resulting treatment efficiency was satisfactory, other methods were...

... in a wide range of reservoirs compared to only using the conventional open hole log suite. The high resolution quality of image data compared to the basic open hole data, for example will allow for fracture visualization down to 2mm. Other petrophysical analysis using basic open hole data will average out...
