... of emulsified acid treatment and characterizing the physics of the flow inside is the objective of our study. The study was performed using vuggy dolomite cores that represent mainly the vuggy porosity dominated structure, while the homogenous cores represent the intercrystalline pore structure. Core flood...

... Good solubility in water and brine. An acid-release rate that was slow enough to allow the fluid to be placed satisfactorily but fast enough to allow the acid release to be complete within two days. The precursor should contain a high concentration of releasable acid. The acid released...

... Abstract There are many ways to stimulate an unlined openhole horizontal well using acid. The simplest way is to just pump acid into the well (i.e., bullhead) without placement control. However, this can often be ineffective. Although still used, such approaches can create massive enlargements...

...). These complex wells impose great challenges with respect to well accessibility for rigless well interventions. One of the initial well interventions, which follow drilling completion, is acid stimulation to remove formation damage. On the other hand, the recent advancement of coiled tubing (CT) enables rigless...
