Perforation: is the process of creating pathways connected between the wellbore and the class produced by the hole cavities through pipes and cement packaging envelope surrounding them.
Punching require special equipment operations, you create cavities minutes during the wrapping pipes and cement Ocean and any other barrier between the class and the wellbore.
There are several types of termination techniques have been developed, and the method of selecting the appropriate method on the properties and the class site.
The main cause of damage to the wellbore and productivity decline in the completion of any perforation process is invasion crushed rock Balhabibat class that generates the restriction (broken area of low permeability).
When the process is done effectively, the perforation allows the flow of hydrocarbons to the bottom of the well to reduce the invasion of fragmented debris.
What is the balanced perforation:
The pressure difference between the wellbore and the reservoir former perforation process can be described as (under equilibrium - balanced - over the balance), wants the situation to be a balance under hydrostatic pressure inside the well envelope is less than the pressure in the class.
Recent studies have shown that the use of low-weight very fluid in the termination in conjunction with the drilling process can increase the dynamic process under the balance in the well to regulate the amount of assistance in cleaning after the perforation process, and resulting in reduced damage to the cortex, as well as increased productivity.
Density Near realizable conventional fluids of the well is about 6ppg, giving her the limits of use in perforating the reservoir depleted, as the intensity level may continue to pressure led to a state above the balance.
And put the well under equilibrium process is necessary and considered a substitute commonplace for the completion of cleaning the well operation, which imposes additional costs that may be undesirable or not an operational process, and in such cases, the reduction of the drilling fluid density with no harm to the chemical properties can offer an alternative effective.
