... Abstract This literature review summarizes the theory and application of chelating agents in acidizing both carbonate and sandstone formations, and in hydraulic fracturing. The objective of this work is to explain the key role that chelating agents play in stimulation. This paper reviews...

... Abstract Success of a matrix acidizing or fracture stimulation treatment depends upon complete coverage of all zones. The diversion process is used to help ensure that stimulation fluids are distributed across the entire interval to be treated. The diversion method best suited for a particular...

... fracturing and how to better manage them. The upper woodford is mostly brittle (see fig. 2 ), with poisons ratio ranging from 0.28 to 0.4. Hydraulic Stimulation in this area has posed little to no problems. Pads are cut short during treatments since loadings are moderate in the breaking of this section...

... Abstract Introduction Unaccounted for solids deposition in oil and gas wells can significantly impact production rates and overall well performance. This study evaluates the impact of including a solid slow-release scale inhibitor in the stimulation package as it relates to production...

... this, the total pressure above the CP is 13,694 psi (0.438 psi/ft × 13000 ft = 5694 psi (hydrostatic) + 8000 psi applied). The differential pressure that the CP is subjected to from the top or upstream side is 4,466 psi (13,694 psi – 9,228 psi). Maximum Differential during Stimulation This calculation...

... Abstract Diagnosing well performance problems before stimulation treatment is an important step to successfully improve a well's productivity. Normally, the method used to do this is well testing. Unfortunately, often no well testing is done in a well before planning a stimulation treatment...

... Abstract With the recent increases in price of a barrel of oil and the growing scarcity of easily exploited oil, efforts to improve productivity of older wells have intensified. Some options for accomplishing this include re-stimulating the well and/or adding laterals that extend past...

... are compared. Well A was treated with a waterfrac design and Well B with a hybrid design. Reflected in the table is that it took 35.9% more fluid at a rate 26.8% higher to pump 47.6% less proppant to fracture stimulate Well A than Well B. Further cost differences between the jobs are a result of higher...

... well stimulation plays a major role in achieving the optimal target production from these reservoirs. Unconventional gas reservoirs require the formation to be fractured by hydraulic means to improve the formation productivity by providing a conductive path and joining the existing fractures and cleats...

Given the volume of fresh water required for hydraulic fracturing during well development, reclaiming produced water as the base fluid for fracturing not only may alleviate the impact of fresh water shortage, it also may lower the cost of well stimulation treatment.

... Abstract The Morrow gas sand reservoirs in southeast New Mexico have permeability values that can range across three orders of magnitude. The best wells are completed naturally; the poorer quality rock usually needs to be fracture stimulated to produce commercially. Early attempts to fracture...

... Abstract For many years, local industry consensus and various authors 1 , 2 , 3 have concluded that with few exceptions 4 , fracture-stimulation of the Morrow sand series in southeastern New Mexico is best undertaken utilizing fluids containing [at least] CO2, KCl, and methanol...
