Did You Know AppIntel
Is There Life After ASP?

After you’re done using great recovery technology like ASP, what’s left to try? Some companies just revert back to water flooding.

ASP can be used to flooding 19 API oil and boost recovery to 50% in conventional reservoirs.

ASP is used to combat fingering and improve sweep.

An ASP flood involves injecting a predetermined pore volume of ASP into the reservoir. Often the ASP injection is followed by an additional injection of polymer. Upon completion of the ASP and polymer injection, regular waterflooding behind the ASP wall resumes again.

AppIntel software can be used to examine the state of the art of ASP flooding comparing applications to field results. In this manner operators can avoid pitfalls experience by other oil companies in implementation.

The combination of the three chemicals is synergistic. Together they are more effective than as components alone.

Addition of a surfactant lowers the interfacial tension between water and oil which helps to reduce capillary pressure in the reservoir. This allows residual oil to be mobilized and produced from the formation.

The use of alkali adds many benefits to an ASP flood. The alkali reacts with elements of the oil to form in-situ surfactants. Additionally, it helps make the reservoir rock more water wet, thus increasing the flood effectiveness. As alkali is inexpensive, this helps to reduce the cost of an ASP flood.

Class Confusion

 Upon the recent revision of the ERCB’s Directive 051 - Injection and Disposal Wells - Well Classifications, Completions, Logging, and Testing Requirements finding D-51 applications can be tricky. The reason? There are now 14 application types through which to sort when looking for an application (see the list below).

The first five on the list below are only used for historical applications. However, the remaining 9 application types are in use today.

Directive 051 Application Types

Guide 51

Guide 51 - Disposal

Guide 51 - EOR

D51: Disposal

D51: EOR

Directive 51

ER - Class II and III

ER - Class II & III

ER - Class II and IV

ER - Class II & IV

Janet is an engineer in charge of several well projects in Alberta.

For a long time, she applied to the board more-or-less “blind” – she applied for what she needed, but wasn’t sure if it was more or less than the board was willing to grant. She often felt grounded in her efforts to maximise her well’s potential.

Then she discovered AppIntel, a database tool that gave her instant access to what her competitors were doing offsetting and nearby her well. Suddenly, she could see what other producers were applying for, and what the board was granting in her area.

Not only that, but AppIntel also alerted her via email whenever there was a new application submitted or approved near her, so she could keep up to date on developments near her project.

This new insight gave her the freedom to apply for – and obtain – the maximum potential for her well.

Now, with newfound wings, Janet soars above her project areas, scoping out who is applying for what, and how to get the maximum allowance for her wells.
