Description

This lunch presentation will discuss two novel reservoir stimulation technologies ExxonMobil has developed that enable the rapid delivery of numerous high-quality stimulation treatments within a single cased wellbore.

Reservoir stimulation in the forms of proppant fracturing, matrix acidizing, and acid fracturing is often required when well performance is restricted by the "as-drilled" wellbore. Unique stimulation challenges can arise when hydrocarbon resources are comprised of multiple vertically distributed discrete reservoir intervals or resources are contained in long productive intervals. These challenges are characterized by the need to effectively manage a balance between the number of stimulations performed, the quality of each stimulation, and the associated stimulation cost. Within the context of current stimulation technology capabilities, the management of this balance can result in operators intentionally bypassing less attractive hydrocarbon intervals, incurring lower production due to poor stimulation effectiveness, or labeling resources as uneconomic based on the cost required to adequately access the reserves.

These technologies were developed for the purpose of improving, or enabling, economic hydrocarbon recovery from formations that contain multiple stacked reservoirs intervals or require the stimulation of long productive intervals.

These technologies:

1) Enable the stimulation of multiple target zones via a single deployment of downhole equipment.

2) Enable selective placement of each stimulation treatment so that they may be designed specifically for each individual zone to maximize well productivity 

3) Provide positive isolation between zones to ensure each zone is treated per design and previously treated zones are not inadvertently damaged; and

4) Allow for treatments to be pumped at high flow rates to facilitate efficient and effective
