“…Leakoff is simulated by using a pressurerelated expression and proppant transport is not considered. Lee et al [182] developed a fixed grid finite element algorithm named HYFFIX. Remeshing and solution interpolation between mesh configurations are avoided in the fixed mesh scheme, but the fracture front needs to be explicitly tracked with a separate method.…”

Along with horizontal drilling techniques, multi-stage hydraulic fracturing has improved shale gas production significantly in past decades. In order to understand the mechanism of hydraulic fracturing and improve treatment designs, it is critical to conduct modelling to predict stimulated fractures. In this paper, related physical processes in hydraulic fracturing are firstly discussed and their effects on hydraulic fracturing processes are analysed. Then historical and state of the art numerical models for hydraulic fracturing are reviewed, to highlight the pros and cons of different numerical methods. Next, commercially available software for hydraulic fracturing design are discussed and key features are summarised. Finally, we draw conclusions from the previous discussions in relation to physics, method and applications and provide recommendations for further research.

“…Mendelsohn (1984) reviewed both coupled fluid/solid three-dimensional fracture models in linear elastic fracture mechanics applicable to the growth of fractures. Lee et al (1994) reformulated a three-dimensional hydraulic fracture simulator by using the finite element methodology and a newly adapted fixed grid. Adachi and Detournay (2008) described the solution of the plane strain problem of a hydraulic fracture propagating in a permeable, linear elastic medium.…”

Ceramsite is a porous engineering material with some basic mineral constituents, and has advantages of low density, high sphericity and high flow conductivity. It should be a good attempt to be adopted in hydraulic fracture, but related researches are really weak. In this paper, laboratory experiments are conducted on ceramsite, coated ceramsite and other typical proppants, which indicates that the coated ceramsite is the best proppant. Then, a coalbed methane well located in the soft coal area in Qinshui basin of China is selected as the research object, numerical simulations and statistic analyses are both conducted to obtain the granularity proportion and parameter optimization by using coated ceramsite. Some findings are achieved. Numerical simulation indicates that the granularity proportion for coated ceramsites of 40/60, 16/40 and 12/20 mesh should choose 1:6:2, which can receive a biggest proppant concentration and strongest flow conductivity. Construction parameters are all optimized for a best fracture performance. Micro seismic monitoring indicates that the actual fracture performance matches well with the simulated result. Drainage performance comparisons reveal that coated ceramsite is suitable for soft coal areas, and can achieve good drainage performances.

“…The complexity of the problem seriously restricts the application of classical models like KGD (Perkins and Kern 1961;Nordgren 1972) and PKN (Geertsma and De Klerk 1969;Khristianovich and Zheltov 1955) in optimizing the fracture design. Currently, the prevailing methods for simulating hydraulic fracture propagation include displacement discontinuity method (Varahanaresh and Ahmad 2015;Dharmendra and Ahmad 2016;Wu and Olson 2016;Zhou et al 2015), discrete element method (Deng et al 2014;Conny and Heinz 2015) and finite element method (Zhang et al 2010;Wang et al 2012Wang et al , 2015Mahdi and Kamy 2015;Gonzalez et al 2015;Wang et al 2016;Feng and Gray 2017a;Lee et al 1994). …”

Multilayered tight sandstone gas reservoirs with low porosity and low permeability are usually developed by two kinds of hydraulic fracturing techniques, including general fracturing (simultaneously fracturing multiple target zones) and separate layer fracturing (sequentially fracturing the target zones from the bottom-up). However, fractures from different target zones are likely to communicate in the fracturing process which detrimentally causes the waste of fracturing fluid and proppants and finally affects the efficiency of fracturing treatment. Therefore, investigation related to hydraulic fracture configurations under different fracturing stimulation treatments is necessary with the objective of optimizing the fracturing design and predicting the production rate. In this paper, a 3D finite element model is established to simulate the propagation of multiple hydraulic fractures in the vertical well, and fracture configurations under different fracturing techniques and formation properties are analyzed and compared. The results indicate that, in vertical wells, stress interference between the fracture tips will accelerate the communication of adjacent vertical fractures along the height direction. And separate layer fracturing is preferable for stimulating multilayered tight sandstone gas reservoirs. Also, adjacent pay zones and barriers with high in situ stress contrast, high tensile strength contrast and low elastic modulus contrast are able to effectively prevent the communication of fractures along the height direction and lead to the increase of fracture length and width, and so does the barriers with large thickness.
