Steven L. Garrettand cost. The particular structure of roller cone bit and the random breakage in heterogeneity rock make it difficult to study the problem of rock-breaking mechanism of roller cone bit under bottom-hole condition. Although, research on this topic has been carried out and drilling speed models under

and the reservoir properties are poor, which makes the reservoir development difficult. Block A is mainly located in the delta front subfacies deposit, and the reservoir is dominated by underwater distributary channel microfacies. In order to improve the development of the reservoir, this paper car

It is commonly believed that large-scale & multi-stage fracturing is an effective way to recover oil from thin, low porosity and ultra-low permeability tight reservoirs. However, the conventional horizontal well dual-packer multi-stage technology is not suitable

Steven L. Garrettpace is complex, the throat is fine and the sorting is poor. The average permeability of the reservoir is 0.01–100.00 mD, and the porosity is generally less than 19%. It is a low permeability reservoir. Based on the geological and engineering parameters of the reconstructed well and the post-fractur

Steven L. Garrettn gas reservoir. The Shanxi Formation reservoir in eastern Ordos Basin, extremely poor in physical property, belongs to a typical tight sandstone. The core samples measure a minimum porosity of 1.23%, a maximum porosity of 13.49%, and an average of 5.4%. In this paper, the development process of tig
