Dapsone is used in the treatment of infections and inflammatory diseases. The dapsone hypersensitivity syndrome, which associated with a reported mortality 9.9%, develops about 0.5 to 3.6% persons treated drug. Currently, no tests are available predict risk syndrome.We performed genomewide association study involving 872 participants who had received as part multidrug therapy for leprosy (39 syndrome 833 controls), using log-additive single-nucleotide polymorphisms (SNPs) imputed HLA...
Deep coal seams show low permeability, elastic modulus, high Poisson's ratio, strong plasticity, fracture initiation pressure, difficulty in extension, and proppants addition. We proposed the concept of large-scale stimulation by network, balanced propagation effective support network fracturing design developed extreme massive hydraulic technique for deep coalbed methane (CBM) horizontal wells. This involves injection with pumping rate + high-intensity proppant perforation equal apertures...
Summary Two-phase flow is generally significant in the hydraulic-fracturing design of a shale-gas reservoir, especially during flowback period. Investigating gas- and water-production data important to evaluate stimulation effectiveness. We develop semianalytical model for multifractured horizontal wells by incorporating two-phase both shale matrix fracture domains. The complex-fracture network, including primary/hydraulic fractures secondary/natural fractures, modeled explicitly as...
Summary Coalbed methane (CBM) has emerged as one of the clean unconventional resources to supplement rising demand oil and gas. Analyzing predicting CBM production performance are critical in choosing optimal completion methods parameters. However, conventional numerical simulation challenges complicated gridding issues expensive computational costs. The huge amount available data that been collected field site opens up a new opportunity develop data-driven approaches rate. Here, we proposed...
Abstract A complex fracture network is generally generated during the hydraulic fracturing treatment in shale gas reservoirs. Numerous efforts have been made to model flow behavior of such networks. However, it still challenging predict impacts various transport mechanisms on well performance with arbitrary geometry a computationally efficient manner. We develop robust and comprehensive for real shales non-planar network. Contributions complexity productivity rate transient are...
Summary Multistage hydraulic fracturing is widely used in developing tight reservoirs. However, the economic and environmental burden of freshwater souring, transportation, treatment, disposal operations has been a topic great importance to energy industry public alike. Waterless one possible method solving these water-related issues. Liquid nitrogen (LN2) considered promising alternate fluid that can create fractures by coupled hydraulic/thermal loadings and, more importantly, pose no...
To address the high rock strength and low drilling rate issues in deep oil/gas geothermal exploitation, we performed mechanical property tests on three kinds of samples (granite, shale sandstone) subjected to liquid nitrogen (LN2) cooling conducted rock-breaking experiments using LN2 jet. Rock-breaking characteristics mechanisms jet, heat transfer features between thermal stress evolution were analyzed. A novel high-pressure jet assisted method was proposed accordingly. The study results...
Producing complex fracture networks in a safe way plays critical role the hot dry rock (HDR) geothermal energy exploitation. However, conventional hydraulic fracturing (HF) generally produces high breakdown pressure and results only single main morphology. Furthermore, HF has also other problems such as increased risk of seismic events consuption large amount water. In this work, new stimulation method based on cyclic soft (CSS) liquid nitrogen (LN2) fracturing, known LN2 is explored, which...
The Stinger PDC cutter has high rock-breaking efficiency and excellent impact wear resistance, which can significantly increase the rate of penetration (ROP) extend bit life for drilling hard abrasive formation. knowledge force response mechanical specific energy (MSE) is great importance improving cutter's performance optimizing hybrid design. In this paper, 87 single tests were conducted on granite. A new method precisely obtaining rock broken volume was proposed. influences cutting depth,...
