Recently I have been looking into making heat maps of options prices/open interest at different strike prices and expiry dates. I have automated the process and have a site here where the heat maps can be viewed.

Just made another flow calculator which takes as inputs the gas composition. It uses that information to calculate the gas density, ratio of specific heats, and uses the Redlich Kwong equation of state to calculate the compressibility factors. The compressibility factors are not bang on, I could switch to the redlich-kwong-soave equation later, comparing to the AER Directive 17 test cases, it is not always within the +/- 0.25% required, but it is close. You can access the flow calculator here. Expect to see an app coming out which replicates this functionality.

Just made an interface to see the structure top values in the Western Canada Sedimentary Basin from actual well data. All the wells are plotted on a map, you can click on a point to view the data from it. You can keep adding the points to view them side by side. You can access the interface here. The data is from here. Currently it is just the top values data sets, which would probably be the most useful for finding traps, and coming up with a stratigraphic section. It appears the data sets do not contain very old wells, but there are still alot (16086), so I apologize in advance if the interface is a little slow. I will optimize it later if it ever becomes very popular.

Just thought I would do a quick look at the optimal allocation of a persons savings when choosing between investing in Cash, Bonds, Canadian Equity, US Equity, or Global Equity. I found the following allocation had the optimum sharpe ratio:




CashBondsTSXUS EquityEAFEGlobal EquityStd DevExpected ReturnSharpe
0.450.394-8.198E-180.1562.479E-16 3.995E-18 0.0030.00050.172

A visual of the point in the portfolio distribution with the best risk/return is below:

This was created using a script from here. What I get out of that, is the equity markets are risky, which is illustrated by the line in the graph having a very low slope. The above was calculated with the maximum allocation in one entity allowed at 45%. If I change that to 100%, then, the best sharpe ratio occurs with 100% cash. This is extremely boring, I wish it were not true.

I used the AGA3 compressible fluid flow calculation for upstream pressure taps from here.. The actual calculator is available here. I have some values in there for a meter run with methane in it just for you to try out.
