致密气、低渗透油藏在有效完井和泄油方面面临着巨大的挑战。假设目标储层可以有效增产，水平井裸眼封隔器完井提供了一种经济高效的方法，可以进入整个水平段。与常规的套管井、固井和有限进入射孔完井相比，裸眼完井面临的挑战是理解和控制水力裂缝的几何形状；具体来说，就是压裂起裂点的数量和位置，以及压裂液进入储层近井区（NWB）的流量。
Tight-gas, low-permeability reservoirs offer a tremendous challenge with respect to effectively completing and draining a target reservoir. Openhole-packer completions in horizontal wells offer a cost-efficient means of accessing the entire lateral section, assuming the target pay can be effectively stimulated. The challenge with openhole completions compared to more conventional cased, cemented, and limited-entry perforated completions is understanding and controlling hydraulic-fracture geometry; specifically, the number and location of fracture-initiation points and the fracturing-fluid flow into the near-wellbore (NWB) area of the reservoir.
