There are a lot of options in the production chart....what do they do?

You can make nearly 65,000 charts using this one tool. Let's dive into the details and make sure you know how to make the chart you want.

The production chart in WellDatabase has been the cornerstone of our analytics since the beginning. The chart capabilities have grown exponentially, all from users requests. Here we'll take a deep dive into the production analytics and show you how to get the chart you want.

Production Analytics Time Chart

X-Axis Options

Moving left to right, the first option allows you to define your X-axis.

Production Analytics Time Chart X Axis Options

The options here are :

  • Time - Total production, aggregated by the group you selected, over the time it was produced
    Production Chart Time Two
  • Type Well - Production normalized by month number. 
    Production Chart Time
  • CUM - Rate vs Cumulative production chart where the X-axis is the cumulative production
    Production Chart Cumulative
  • Forecast - Existing production, like the Time option, but with our pre-computed production forecasts appended to the chart
    Production Chart Forecast

One thing to note is that these chart options do not change the way the data is aggregated. That is very important to note for things like Type Well & CUM options. Luckily, that's the next set of options.

Aggregation Settings

Aggregating the production data can be done in many ways. If you're looking for an operators total production, then Sum would be the proper option. If you're looking for a type curve of the average well, then Average make sense. If you want to get more detailed on the percentiles, P10, P50, and P90 are perfect.

Production Analytics Time Chart Aggregate Options

Here is a run-down on the options here:

  • Count - Simple count of wells producing.
    Production Chart Count
  • Min - The minimum production value at each step. Note, this is not just the lowest producing well, but the lowest producer over each period dictated on the X-axis.
    Production Chart Min
  • Max - The max production value at each step. Same note applies as the Min option.
    Production Chart Max
  • Average - Average production for each period along the X-axis.
    Production Chart Average
  • Sum - Total values for each period. Especially useful on the Time option.
    Production Chart Sum
  • P90 - Data here is in the 90th percentile. This means that the 90% of the wells in our group will be at or higher than the values in this chart.
    Production Chart P90
  • P50 - The data in this chart is the median value for each period. While close to the average many times, it is different.
    Production Chart P50
  • P10 - Data here is in the 10th percentile. This means that it represents the top 10% of wells in this group.
    Production Chart P10
  • P10-P90 - The P10-P90 option helps to show the variance between the top 10% and the bottom 10% for an operator. It naturally will be a higher value for periods of high production. This chart helps to show consistency with the wells in the group.

  • Swanson - Sawnson is a weighted average of P10, P50, & P90. The formula used is P10*0.3 + P50*0.4 + P90*.03.

Volume Type

The next option is how you choose what volume you want to analyze. We won't show images of each of these since they tend to be pretty self explanatory. 

Production Analytics Time Chart Volume Option

The options here are :

  • Oil (bbl/m) - Monthly oil production (this is how it is reported to all regulatory agencies)
  • Oil (bbl/d) - Daily oil volumes calculated by simple division of monthly production and days in the month.
  • Gas (mcf/m) - Monthly gas production 
  • Gas (mcf/d) - Calculated daily gas volumes
  • Water (bbl/m) - Monthly water production 
  • Water (bbl/d) - Calculated daily water volumes 
  • BOE (6:1) - Monthly BOE volumes using the standard energy ratio of 6:1 - mcf Gas : bbl Oil
  • BOE (20:1) - Monthly BOE volumes using a financial ratio of 20:1 - mcf Gas : bbl Oil
  • BOE/D (6:1) - Daily BOE volumes using the 6:1 ratio
  • BOE/D (20:1) - Daily BOE volumes using the 20:1 ratio
  • GOR - Gas oil ratio values for each period

Normalization Options

In the world of unconventional plays, normalization of production numbers has become a requirement. With varying amounts laterals, proppants, and more, normalization helps you create a better apples to apples comparison.

Production Analytics Time Chart Norm Option

Each of these options does the same simple division. It is production volume divided by the option you select. The options are :

  • None
  • Lateral Length
  • Lateral Length / 1000 ft
  • Perf ft
  • Perf ft / 1000 ft
  • Proppant lbs
  • Proppant Lbs / 1000 lbs

Rate vs Cum Option

A very basic option that can be applied to any chart you have built is plotting the rate vs the cumulative. This can be very useful when you're comparing things like type curves.

Rate - This option shows the value you selected as-is. This means that the combination below, Type Well showing Average Oil (bbl/m), shows the values per period.

Production Chart Average

CUM - The CUM (or cumulative) option will show you the values using a running sum. Each period's value is added to the previous to roll up to the cumulative number.

Production Chart Cum

Type curves naturally have many dynamics at play. Initial production numbers, initial decline numbers, the b-value of the decline, and more. This chart can be more helpful to see what the net effect of everything together ends up being. 

This also makes a great segue to the next option, the Log button.

Log Scale

Production data is usually viewed on a log scale. The decline from the initial months to the tail is just too drastic to be able to view it on a numeric (non logarithmic) scale. However, in the case above using the Cum option on a type curve, the data gets too muddy to discern what is happening. This is where the turning off the Log scale can help.

Production Chart Cum Non-Log

Now we can more clearly see where the production profiles diverge from each other and glean additional insights.

Chart Type

Finally we get to the last set of options and that is the chart type. By default (and in every sample here), we use the line chart. The data just lends itself nicely to it. However, the other options do have their roles. Let's see what they look like.

Production Analytics Time Chart Vis Options

  • Column - Can be useful to better compare specific data points. Can also get very messy with too much data.
    Production Chart Column
  • Column Stack - Great for visualizing the total dataset while being able to easily break out which groups account for what piece of the total production.
    Production Chart Column Stacked
  • Line - Very useful just about everywhere and the default for a reason.
    Production Chart Sum
  • Line Stack - Back to comparing the individual groups vs the whole.
    Production Chart Line Stacked
  • Area - Somewhat like the column chart. Area has some level of transparency so you can still see the data series underneath others.
    Production Chart Area
  • Area Stack - Another good one for viewing trends within the whole.
    Production Chart Area Stacked
    This one is pretty popular with the vintage look.
    Production Chart Vintage Stacked Area
  • Percent - Perfect for answering the specific question of exactly what percent of the whole does a group account for.

So six years later, we're done. Congrats if you made it this far. As you can see, the production charts can do a little bit of everything. Hopefully it helps you make the exact visualization you need.
