During the exploration and development of unconventional oil and gas resources, the magnitude and direction of in situ stresses are key parameters for sweet spot forecast, stimulation parameters selection, horizontal well arrangement and borehole stability analysis (Olsen et al., 2009; John, et al., 2011). In situ stresses have been previously focused on, but unfortunately they are not well understood when stimulation and completion decisions are made.展开更多

Elastic property of shale is useful for seismic profile explaining, brittleness estimation, completion and hydro production design (Arjun et al., 2013). For the reason of different mineral components, shale samples from different reservoir or different layers in the same reservoir have different elastic property generally (Homby et al., 1994; Joshi et al., 2012), it is thus necessary to study elastic property of shale, especially in complicated structure region.展开更多
