Borrowing from many years of experience with interwell tracing, several families of non-radioactive chemical compounds were identified that could potentially be placed in segmented portions of the frac ,fluid, so as to more directly measure the ,flowback, efficiency of each ,fluid, segment. Armed with this ,flowback, profile data together with the net pressure history of the frac treatment, it was believed that much could potentially be learned both about the dynamics of segmented ,fluid, …

Initially, the oil or gas is allowed to flow from the well along with the majority, of frac fluid,, referred to as, flowback fluid., The, flowback fluid, is separated from the natural gas or oil and stored at the wellsite. The well can flow (or produce) for years, but the, flowback, of, fluid, only occurs over days or months. The carefully recovered, flowback fluid, is either reused for another well or disposed in government …

The loss of prop pant during the ,flow back, process in hydraulic ,fracturing, treatments has been a problem for many years. The effectiveness of the fracture treatment is reduced. A well cleanup is often required to remove the unwanted proppant from the

Water for hydraulic fracturing - PetroWiki
Water for hydraulic fracturing - PetroWiki

15/1/2018, · Hydraulic fracturing is the process of pumping fluid into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.

Before putting the well on flowback, the induced fractures are occupied by the compressed fracturing fluid. Therefore, analyzing the produced fracturing fluid should in principle be able to characterize the induced fractures, and complement the production data analysis. We develop a rate transient model for describing the fracturing fluid flowback.

The fracturing fluid is flow out from the, wellbore, through the, oil nozzle, when the flowback begins. Taking the wellhead as the research object, and according to the Bernoulli equation and continuity equation, the fracturing fluid flowback velocity in the oil nozzle at the moment of t n is derived.

The ,fracturing, takes place at the start of the wellbore's life cycle. The injected ,fluid, is often water, and it usually contains various chemical additives and a proppant, like sand, to keep the fractures open so oil and gas can flow to the well.
