Hydraulic
fracturing is a well stimulation process performed at reservoirs with low
permeability to improve the flow of hydrocarbon into wellbore. Certain
chemicals would be injected with a very high pressure into the well by using
sand as a proppant agent because of its efficiency in removing the obstacles.
Sudan, a north-African nation has abundant silica sand sources that may wellact as an agent in Hydraulic fracturing in Sudan.
The
process requires an array of specialized equipment and materials; it is
involves injection of frac-fluid at a high pressure into a selected section of
wellbore; this fluid pressure creates a fracture extending into the rock medium
which contains oil or gas.
When the fluid pumped into a well, necessarily the
pressure rises, and at some point something breaks (either the rock or the
equipments); as the rock is generally weaker than steel, the formation will
breaks, resulting in wellbore fracturing along its axis. To maintain fracture
opening during the production life of the well, solid substance with specific
characteristics (known as proppant) injected to the fracture to suspend the
fracture. Read more.................
