Methods comprising: injecting into a wellbore in a subterranean formation a multi-particle lost circulation material composition comprising a base fluid and a particle blend comprising substantially cylindrical particles and substantially spherical particles and wherein said particle blend comprises: degradable particles of at least three different sizes and wherein a first-sized particles and a second-sized particles are substantially cylindrical and a third-sized particles are substantially spherical.

Methods of using multi-particle lost circulation material in highly porous or fractured formations

An integrated hydraulic fracture design model that utilizes elastic fluids with high proppant suspension and low required power for injection into a hydrocarbon-bearing, subterranean formation. The integrated physics-based approach utilizes a hybrid friction model to compute viscous and elastic behavior to estimate pressure losses at different pumping conditions coupled with a novel geomechanical model capable of modeling proppant transport with elastic fluids in planar hydraulic fractures and natural fractures. An integrated process to optimize hydraulic fracture design evaluates and quantifies the proppant-carrying capacity of elastic fluids and its impact on the proppant transport process, and low water requirements.

Application of elastic fluids in hydraulic fracturing implementing a physics-based analytical tool

The disclosure pertains to the increasing the amount of stimulated efficiency and production from a given well area by determining a number of diverter slugs and the timing for the injection of the slugs for the given well area. A number of data sets are determined using Monte Carlo analysis, each data set including a quantity of diversion slugs and the timing for the injection of the diversion slugs. A simulation is performed on a plurality of the data sets to determine the production outcome of employing the data set in a stimulation job. The results of the simulation are used to determine the optimized data set for the stimulation job.

Systems and methods for optimization of the number of diverter injections and the timing of the diverter injections relative to stimulant injection

The disclosure pertains to the determining the efficiency of stimulation operations in a hydrocarbon well. Stimulation is performed in a hydrocarbon well and various data is obtained therefrom. The data is used to develop a simulation of fluid flow in the well and the simulation is used to model a synthetic tracer log, which corresponds to a modeled level of efficiency. Numerous synthetic tracer logs may be generated in this way so that tracer logs are available for a variety of different stimulation efficiencies. In order to determine the efficiency of an actual stimulation, the real tracer log of the stimulated well may be compared to the synthetic tracer logs in search of a match. When the real tracer log matches a synthetic tracer log the modeled efficiency of the synthetic log may be used as the actual or true efficiency of the real well stimulation.

Systems and methods for evaluating and optimizing stimulation efficiency using diverters

The disclosure pertains to the design and implementation of a diversion procedure for geologic openings. Embodiments involve performing a screening analysis to determine if a well or formation is appropriate for stimulation. If a well is appropriate, a modeling analysis is performed to determine candidate parameters for a diversion procedure. The analysis is divided into two segments, a dry analysis of jamming and a wet and full-physics-based analysis of plugging. The jamming analysis provides candidates to the plugging analysis to reduce the work of the more intensive wet full-physics modeling.
