Special Issue Information

Dear Colleagues,

The rapid development of unconventional resources and energies has led to the use of hydraulic fracturing technology in petroleum engineering. Hydraulic fracturing stimulates a natural gas, oil, or geothermal well to maximize extraction.

It is one of the key methods of extracting unconventional oil and unconventional gas resources. In recent years, many researchers and scientists have made great achievements in this field. However, some urgent problems, such as geomechanical and huge environmental problems, still need to be solved. Therefore, it is necessary for us to find a suitable and innovative way to develop this technology. Numerical analysis and modeling of hydraulic fracturing is helpful in identifying tight oil/gas formations and providing accurate solutions for optimizing well spacing for the design of zipper-frac wells.

This Special Issue covers a comprehensive array of manuscripts and research papers that explore various aspects of hydraulic fracturing, including early design, modeling, field practices, and characterization.

During the hydraulic-fracturing process, stress interference occurs among multiple wells and fractures, potentially affecting the trajectory of hydraulic fracture propagation. Previous studies have largely overlooked the influence of proppant support stresses on the trajectories of fracture propagation. This paper establishes a mathematical model, grounded in the boundary element method, designed to compute the propagation of multiple fractures, considering both proppant support on the fracture surface and dynamic perturbations within the local stress field. The findings of this research reveal that the stress field induced by hydraulic fracturing exhibits dynamic evolution characteristics, necessitating a comprehensive study of the fracture initiation and extension across the entire fracturing time domain. The effect of the residual fracture width under proppant action on the in situ stress field cannot be ignored. During simultaneous fracturing, hydraulic fractures are inclined to propagate in the direction of the maximum horizontal principal stress, particularly as the in situ differential stress escalates. Staggered fracturing between wells has been proven to be more effective than head-to-head fracturing. Simply increasing the well spacing cannot solve the problem of inter-well fracture interference. In zipper fracturing, adjusting the fracturing sequence can inhibit the fracture intersections between wells, thereby controlling the trajectory of fracture propagation. The aforementioned research has considerable significance in guiding the control of fracture morphology during hydraulic-fracturing processes. Full article

High pressures during drilling with the aim to obtain hydrocarbon formations (oil and natural gas) can cause an uncontrolled eruption. Therefore, it is necessary to look for warning signs of kicks and control the formation strength. The aim of this article is to show a real process of fracture pressures during a gas kick and their possible solutions. The evaluation of the lithological structure of formations and the correct evaluation of seismic measurements are closely related to the issue of fracture pressures. The contribution also includes software data for detailed analysis and calculations of formations pressures. We point out the incorrect calculation of the geological lithology and employ a casing shoe; it is a risky decision to use a formation integrity test as opposed to a leak of the test. Based on theoretical knowledge, we compared and verified the recalculation of pressure coefficients during the gas kick. In our case, we propose possible solutions for cracking a casing shoe. We point out the importance of correct calculations for a safe and economical purpose. In this post, a theoretical example was shown where the system of casings was correctly designed, and based on this, we obtained ideal values of the fracture pressures. In the end, we proposed an algorithm to simplify work procedures during well control to minimize formation pressures against the deposit and casing shoe. Full article
