ASP flood quadrupled

To celebrate, one operator quadrupled his ASP flood

There are two $50 oil points. WTI passed the first point on the way down. The other we just passed last week on the way up.

The first $50 oil point was seen with pessimism and fear.

The more recent $50 oil point was a day of cheering and optimism.

One operator is even quadrupling an ASP flood. His application contains his work on injectant composition and his injection pattern.

Without AppIntel, how would you find out how others are improving their ASP floods?

You can see his proposal to the AER by ordering his application from AppIntel. Just click the button below.

Polymer is expensive

Injecting polymer into a floods is much more expensive than just injecting water. Even if the polymer shuts off some water and encourages more oil production, the additional cost of injectant can seriously mar the flood economics.

Polymer or ASP?

Most polymer floods in Canada are now ASP floods. The staged ASP strategy amplifies recovery. But ASP is even more expensive than polymer floods.

The P in ASP stands for polymer. The polymer is expected to set up and plug areas in the reservoir where water has already swept. The polymer also increases the viscosity of the injectant to reduce fingering and increase recovery.

S is for Surfactant. Surfactant changes the wettability of the system which causes more oil to be mobile. Then the oil can be pushed by the polymer.

A is for Alkali. Alkali pretreats changing the acidity of the formation water so the surfactant can do its job. In the reservoir, the Alkali also creates a polymer soap -- a natural surfactant.

Get the real ASP story from applications

A, S and P chemical manufacturers all claim superior results. But the best way to be sure is to study results in others' fields.

If you can find a field that is under ASP flood, you can study the success (or failure) for yourself. You can look at the production results. You can determine how much the reserves increased. You can decide how much the water cut dropped.

Applications have a much more trustworthy story about the success and failure of ASP than any other source. Better than sales literature. Better than technical papers.

Every application is ground-truthed to an actual well location in UTM or Lat/Long. You can follow up your reading of an ASP application with an actual look back at the production history before, during and after the ASP injection.

Better than technical papers

Applications are a much better source of information than technical papers for two reasons. First, applications are adjudicated by a picky regulator rather than a peer reviewer. The regulator is interested in increasing reserves, not in exploring science.

Second, applications explore both the benefits and also the problems and difficulty with ASP. Technical papers usually only focus on one dimension of field or lab results.
