Heavy Oil

Industry Challenge:

Recovery from heavy oil reservoirs in Canada’s oil sands using primary production techniques is typically on the order of 5 to 10% of original oil in place.

Operators seeking to increase this recovery rate have considered a variety of enhanced oil recovery techniques such as water, polymer floods and even steam injection.

One of the key challenges is that the primary recovery process, usually referred to as Cold Heavy Oil Production with Sand (CHOPS), consists of producing...

Industry Challenge:

The use of horizontal wells in primary heavy oil operations offered the promise of higher flow rates due to the much greater length of reservoir exposure offered by the horizontal section of the well.

Unfortunately, this also introduced the challenge of transporting the sand produced with the oil along the horizontal section.

Typically, flow rates within the wellbore were generally too slow to transport the sand during normal production.

In addition, during well shutdowns,...

Abstract

Many wells producing medium or heavy oil from unconsolidated sandstone reservoirs experience high water production while still at relatively low recoveries. Water production causes numerous operational problems leading to increased operating and capital expenditures for higher volume artificial lift systems and water handling facilities. The recent development of Downhole Oil/Water Separation (DHOWS) systems has provided operators with an alternative approach to contend with increased...

The Industry Challenge:

Canada has demonstrated the ability to economically produce heavy oil using a non-thermal method referred to as Cold Heavy Oil Production with Sand (CHOPS).

Operators from around the world are interested in using CHOPS to develop their heavy oil reservoirs; however, they do not have sufficient expertise in this recovery technique to determine if it is feasible.

How We Help:

C-FER can review the reservoir characteristics of a heavy oil reservoir to determine if it is...
