Montney Part 3: Players, Type Curves & Maps

September 13, 2011 by

Editor’s Note: While VISAGE rebranded to VERDAZO in April 2016, we haven’t changed the VISAGE name in our previous blog posts. We’re proud of our decade of work as VISAGE and that lives on within these blogs. Enjoy.

(Part of a joint series combining the power of VISAGE visual analytics software with geoLOGIC’s value-added data live from the gDC)

Today’s blog will cover quite a spectrum of information including The Montney Players, the top wells, type curves and maps generated by taking VISAGE percentile information and plotting it in geoScout. So let’s jump right in….

The Montney Players

The top 12 companies (18% of the companies in the Montney) accounted for 90% of May’s production. Those same 12 companies have 79% of the producing wells. The chart below shows a breakdown of all of the producers with the following information being shown:  COMPANY (producing well count): (mmcf/day) % of Total production

Type Curves Part 1: Comparison of Well Profile Types

Normalized Comparison of Well Profile Types

Type Curves Part 2: Normalized Distribution of Initial Production Rates

Before we show any additional type curves of Horizontal Montney Wells it is important that we provide a context for what we will be looking at. The remaining horizontal well analyses will be for all producing horizontal wells that came on production in 2007 or later. This collection of wells has some massive producers that have the potential to significantly skew data results. therefore it is important when doing any of this analysis to support decisions that the collection of wells has been scrutinized by professional engineers and geologists familiar with the play. The follow chart identifies six anomalously large wells that fall outside the main distribution of initial rates (i.e. average of months 2 and 3).

 

 Type Curves Part 3: Comparison of Normalized Production Profiles by On Production Year

The best year for the Montney (in terms of average production profiles was 2007). Subsequent to that production profiles have tried to catch up to these rates, with 2011 looking to be the most promising. Something anyone analysing data needs to be aware for future analyses is that there was a temporary shut-in of production in May of this year. This will profoundly impact type curves as can be seen in the 2011 values in this chart.

Normalized Production by On Production Year

 

Type Curves Part 4: Percentile Trendlines

Another method for understanding the variability in production rates that make up a type curve are Percentile Trendlines (read about this VISAGE feature in our blog So What Is The Problem With Production Type Curves?). Here we can see that the average initial rate is about 2600 mcf/day, 80% of the values that make up this number fall between 331 mcf/day and 5295 mcf/day.

Maps: Taking VISAGE data and plotting it in geoSCOUT A picture is worth a thousand words … and two pictures are worth two thousand words or more? That’s why VISAGE and geoSCOUT compliment one another so nicely. VISAGE allows you to visually explore data with slice and dice capabilities using charts … while geoSCOUT lets you take the same data and view it in a geospatial context. The combination of the two can garner tremendous insights (I’ll be doing a future blog with someone who uses VISAGE to calculate remaining reserves and geoSCOUT to plot them on a map). So for this example we took 342 wells that we could get horizontal length and frac count from (derived in VISAGE) and plotted them on a series of charts. The one chart that seemed to present a (more) meaningful picture was a normalized type curve by Frac Spacing. The chart is shown below … click here to go to the gDC blog to see some map illustrations.
