Well Evaluator Case Study

Benchmarking the Eagle Ford play

Investors want to know: why is one operator underperforming versus its peers?

As institutional investors' demands for E&P capital discipline intensify this year, upstream companies have reined in spending and softened aspirations for production growth. Underperformers are at top of mind as investors assess financial risks.

We benchmarked an underperforming Eagle Ford operator to analyse:

  • Well spacing
  • IP per foot vs proppant per foot
  • Subsurface layers

Our team of upstream experts regularly guide customers who need to gain a clear, concise and comprehensive view of why their investment is floundering. Lately, customers expressed growing concerns surrounding an under-performing operator in the Eagle Ford. Customers want to know why it has underperformed versus its peers and why debt is growing.

We've utilized Wood Mackenzie Well Evaluator to help our investor customers with peer benchmarking. Here's a look at how we did it.

Step 1: We filtered for the criteria that best fit the operator's acreage and drilling activities in the Eagle Ford

i)                 Hawkville Condensate and Maverick Condensate subplays

ii)                Dimmit and Webb Counties

iii)               Top 5 area operators

Step 2: Next, we refined the previous filter to only include completions from the last two years

This helped us narrow down the most recent production performance, which showed the operator's assets are falling short compared with their nearest competitors.

Step 3: To further assess the underperformance, we decided to take a look under the hood of producers operating in the same areas

First we evaluated their well spacing – the bulk of their wells are on 660-foot spacing, versus the underperformer's 330-foot spacing. To correct underperformance, the operator has promised to upspace wells, so there's hope that the corrective steps will improve future results.

Step 4: In the next step, we filtered down further into the operator's corrective steps – are they actually working?

While some wells are now up to 660-foot spacing, the company continues to complete older sections that were drilled on 330-foot spacing.

We drew up the results of the operator's initial production (IP) per foot vs proppant per foot, in case the previous type-curve analysis didn't fully reflect the new wells. The results weren't promising – the operator's performance is low compared with its closest competitors in the same region.

Step 5: In our final step we pondered – is geology to blame?

It's possible. The nearest competitor's acreage is in an area with higher total organic carbon (TOC) compared to that of the under-performing operator. 

Wood Mackenzie Well Evaluator subsurface layers show Eagle Ford acreage TOC.

Well Evaluator's new subsurface layers helped us dive into the TOC in the underperformer's acreage. 

Our conclusions? It's likely that the underperforming producer will be challenged to make significant improvements. We'll continue to watch as fresh production data emerge to see if they can turn this ship around.
