摘要:
To improve or optimize a wellbore treatment operation, a target net treating pressure may be determined and the constant net treating pressure maintained to effectively enhance formation breakdown and fracture complexity as well as provide a reduction in wear and tear of equipment and completion time. The target net treating pressure may be based on one or more treatment parameters and these parameters may be adjusted during the wellbore treatment operation to maintain a constant net treating pressure at or about the target net treating pressure. The injection rate or pressure of a treatment fluid may be adjusted to maintain the constant net treating pressure. Measurements associated with the wellbore treatment operation may be compared to an operational constraint and adjustments to the wellbore treatment operation may be made based on the comparison. The wellbore treatment operation may be terminated based on a parameter falling below or exceeding a threshold.
