... of the unconstrained growth with relatively high reservoir permeability, the created fractures potentially are of limited length and of relatively good conductivity. According to a semi-analytical bi-linear production model, these parameters are nearly optimal for the particular reservoir. Preference for highly...

Paper Number: SPE-191423-18IHFT-MS
... Abstract The performance of acid fractured wells depends on the conductivity distribution along the acid penetration length, which is a function of reservoir properties, treatment design and execution. The previously published models for fractured well performance assume constant fracture...

... unless artificially propped open in some fashion. The advantage of combining the two approaches (acid+proppant) is not only an improvement in the natural fracture conductivity through the acid etching, but also yields a longer lasting conductivity in the main fracture from the emplacement of the proppant...

... in the formation is competing with the flow in the fracture even though the fracture is highly conductive. Fig. 4 shows the required acid volume for 15 wt% HCl and 28 wt% HCl to breakthrough at different injection rates. The total injected acid volume required to breakthrough for 28 wt% HCl is always less...

Paper Number: SPE-191433-18IHFT-MS
... Abstract In naturally fractured carbonates, the efficiency of acid fracturing stimulation can be hindered due to the decreased effective length and conductivity of created fractures, and acid loss into natural fractures is one of the main reasons for the reduced efficiency. At the same time...

... "The production rates of many fracture-stimulated wells globally are curtailed because of sustained proppant-flowback issues. As proppant produces out of the fractures along with the produced fluids, fracture conductivity diminishes with time and closure stress as the fracture width decreases...

... Abstract The overall success of hydraulic fracturing treatments is determined by proppant placement, pay zone coverage, and conductivity sustainment. Common strategies to maximize fracturing success are to increase concentration and use high-strength proppants. Conventional low-viscosity fluid...

... and displacements during fracture closure will impact the overall conductivity, especially for acid fracturing treatment, where flow paths are supported by the roughness of unevenly acid-etched fracture walls. In this paper, we present a new approach to model acid fracture conductivity by allowing combined normal...
