Over the past few decades, hydraulic fracturing, a well-stimulation technique commonly used for extracting hydrocarbons within unconventional reservoirs, has played a significant role in transforming the energy industry. Multiple studies and field trials have proven that an effective, efficient, and economical approach is critical for such operations. However, even after numerous fracturing jobs conducted across the globe, they are still related with high risk. Moreover, the exploitation of such reservoirs is water- and resource-intensive as compared to conventional reservoirs. This is crucial, especially in offshore operations and arid regions. A comprehensive investigation through a traditional fracture design process was conducted for a candidate Middle Eastern reservoir. Through the construction of strategically constrained cases in the presence of complex natural fracture sets, this novel investigation allowed the model to successfully isolate and characterize the key fracture design parameters that influenced fracture geometry for the candidate field and in turn the requirements with respect to water usage and resource consumption. The results indicate that for the given field conditions, fluid and proppant optimization is critical to achieving maximum recovery. The influence of natural fracture is highly critical and greatly influences the overall productivity. Simulations further indicate water requirements for the candidate field ranging from 3.5 to 5.8 million gallons of water per operation, which is significant in water-scarce regions. The findings of this study and the proposed workflow can assist to better understand the distinct contributions of key fracture design and operational parameters that are critical under the current volatile market conditions.

Since its introduction almost 50 years ago, hydraulic fracturing has been the prime engineering tool for improving well productivity either by bypassing near-wellbore damage or by actually stimulating performance. Historically (and in many instances erroneously), the emphasis for propped fracturing was on fracture length, culminating in massive treatments for tight-gas sands with several million pounds of proppant and design lengths in excess of 1,500 ft. More recently, the importance of fracture conductivity has become appreciated. This has led to exciting "new" applications of propped fractures in better-quality reservoira as illustrated by North Sea wells, stimulations in Prudhoe Bay, and "frac-pack" operations in the Gulf of Mexico and Indonesia, Wldle better understanding and new technologies are being used today, the actual application of fracturing to higher-permeability formations is not new. During early development of fracturing, nearly all applications were for moderateto high-permeability zones (becimse low-permeability rock was of little interest at oil prices of $3/bbl).While tremendously succeaatirl at increasing productivity index (PI), these early high-permeability treatments were doing little more than bypassing damage. More recent development of improved, artificial proppant, cleaner fluid systems, and new technologies have changed this, makhtg it possible to alter reservoir flow and stimulate production from moderate-to high-permeability reservoirs. The primary new tool in the engineer's arsenal is the development of tipscreenout (TSO) fracturing. WMle higher-permeability formations provide the new applications, the actual philosophy shift for fracturing occurred with the massive tight-gas stimulations. Traditionally applied to fracturing of poor quality reservoirs, these treatments represented the first engineering attempts to aher reservoir flow in the horizontal plane. The development of TSO fracturing to allow creation of extremely wide, highly conductive fractures has extended this ability to alter reservoir flow to better formations. However, creation of artificial, highly conductive flow paths in the earth also creates an ability to alter reservoir flow in the vertical plane, opening the way for propped fracturing to evolve from a stimulation technology to a total reservoir-management ted This paper uses field examples to trace the history, development, and application of TSO fracturing to high-permeability formations, including fracturing to increase P]. as well as appl icatiorrs aimed at improving completions in unconsolidated sands. Potential applications of fracturing to bypass the need for sand control are explored. Finally, the use of fracturing as a reservoir-management tool is examined through use of a propped fracture to alter the vertical flow profile of a well to maximize reserves. This particular use of fracturing leads to cases where careful design of both fracture length and conductivity is required: i.e., too much conductivity is as damaging to reservoir management as too...

“…According to the calculations [3,4], the maximum operational benefit (incremental oil production) is achieved in terms of maximum fracture length (in the considered intervals). However, on the other hand, a condition imposing a limit on the fracture length includes the economic criteria defined by the cost of materials and related works when carrying out hydraulic fracturing [5][6][7].…”

The article analyzes the economic performance of wells with hydraulic fracturing. The effectiveness of using hydraulic fracturing technology in the development of the oil reserve area with the low-permeability zone is defined in terms of its economic feasibility. To do this we studied the dependence of the net profit value of the enterprise, accumulated during the billing period, from the fracture length and the oil prices on the international market. As the estimates for calculating, we used the economic activity data of one of the oil-producing enterprises of Tatarstan. The dynamics of growth of the accumulated net profit value was studied taking into account the options and different fracture lengths in the low-permeability zone. It was found that the greater the fracture length is near injection wells in the low-permeability zone, the lower the accumulated net profit value is, and vice versa.
