Abstract
A disintegrable oilfield chemical composite includes a core containing an oilfield chemical and a disintegrating agent containing at least one of a phase change material or a gas-producing material; and a shell encapsulating the core. A method includes introducing into a subsurface formation a treatment fluid including the disintegrable oilfield chemical composite; heating the disintegrating agent to cause the phase change material to expand, or to cause the gas-producing material to produce a gas, or a combination thereof to break the shell; and releasing the oilfield chemical from the disintegrable oilfield composite.
