Formation fractures occur when the injection is performed at a pressure exceeding the in situ stresses and fissure propagation occurs.

Induce fracture pneumatic fracture granite.

The mineralogical mechanical and hydraulic properties of this granite can be found in ji et al. Fracturing experiments on shale and granite using fluids of different viscosities show that sc co 2 can induce a shear dominant fracture with more branches and generate cracks extending more. Petropedia explains induced fracture induced fracturing is performed with the help of hydraulic fracturing technique in shale formations where the hydrocarbons are tightly packed between the non permeable rocks under great pressure and. 1b in two cylindrical core samples without visible cracks on the sample surfaces.

These geologic for mations however often contain interconnected fractures or fault zones on a continuum of scales bonnet et al 2001 caused by cooling and or tectonic processes. Thereby creating fractures or fissures in soil or rock formations. Ji and others published overpressure induced fracture slip triggering in granite find read and cite all the research you need on researchgate. We investigate mixed mode fracture initiation and propagation in experimentally deformed granite and sandstone.

Typically pneumatic fracturing is used in formations where the fractures will remain open for a long time without support hence propping agents to hold fractures open are not commonly employed. 2019 we prepared a sawcut fracture fig. Line rocks such as granite basalt tuffs etc have been suggested as suitable sites for the construction of nuclear waste repositories in many countries. 1a and a natural fracture fig.

We performed a series of asymmetric loading tests to induce fractures in cylindrical specimens at confining pressures up to 20 mpa. The observations in the single flawed sample sw 1 is used to prove that the pre existing fractures can be propagated. Loading was controlled using acoustic emission ae feedback control which allows studying quasi static fracture propagation for several hours. Bukit timah granite is a triassic igneous rock sourced from the central region of singapore island.

In this pioneering study injection induced fracture propagation tests were performed on the single flawed and double flawed granite samples receptivity. Pneumatic nitrogen injection system source navfac pneumatic fracturing uses air or other gas to induce and propagate fracturing. Hydraulic fracturing is used to induce the fractures in the formation so as to enhance oil or gas production.
