Proppant Chemistry
Proppants are a great tool
when stimulating and fracturing formations. The following
explanation provides an outline of generalized steps taken when
fracturing a formation.
|
In a producing formation, hydrocarbons are
produced from the formation into the pore spaces. Over time,
the pore spaces become plugged with hydrocarbon deposits, scales,
and other material. |
|
Pressurized liquid and gases are injected into
the pore spaces which open these spaces (lengthen, widen, and
splinter). Liquids clean and remove debris to further open
pore spaces. |
|
Once the spaces have been cleaned and expanded,
proppants are introduced to keep the pore spaces open once the
chemicals have been released. |
|
Cleaned, widened, and lengthened pore spaces will
provide increased production now that the |
Chemicals are used to create
proppants, pressurize formations, clean pore spaces, to ultimately
restore oilfield production.
