Overview

Montney Domain Areas

Not all Montney is Created Equally

• The Montney resource play covers approximately 130,000 km2 stretching from west central Alberta to NE British Columbia.

• There are more than 4,100 horizontal wells with multi-stage completions within the Montney.

CDL has defined three key parameters

• Geological Facies

• Reservoir Temperature

• Reservoir Pressure

Basis of Comparison

• Segregating the Montney into 26 discrete domains or pods makes an effective basis of comparison

Domain Parameters

• CDL has identified 4 distinct geological facies

Shoreface

Coquina

D5 Subcrop

Distal Facies

• Reservoir temperature has 4 regimes

< 60 ⁰C

60-80 ⁰C

80-100 ⁰C

>100 ⁰C

• Reservoir pressure has 6 regimes

Deep Basin

• < 8 kPa/m

• 8-10 kPa/m

• 10-12 kPa/m

• > 12 kPa/m

Aquifer

• < 8 kPa/m

• 8-10 kPa/m

The domain parameters determine what type of production be predominant in an area: dry gas, liquids-rich gas & condensate, liquids-rich gas or oil.

MONTNEY SPOTTER

Probabilistic Type Curve Development

• Within each domain or area of interest the producing Montney wells are identified.

• These are individually reviewed to select those wells that are “typeable” (min 6-mo consistent production history)

• Assignment of terminal decline characteristics

• Probalistic analysis is run on the typeable well group to generate PTCs (P10, P20, P30, … P90)

• By-products are added as a ratio to the primary produced fluid:

for oil wells, GOR (scf/bbl)

for gas wells, estimated free liquids recovery and yield (bbl/mmscf)

BOE Type Curve

• Boe type curve

Focus Domains

1. Kakwa-Karr

• Rich Gas

• Storm-Dominated Shoreface

• Deep Basin 10-12 kPa/m

• 80-100 ⁰C

2. Beg/Town

• Rich Gas

• Distal Offshore including turbidites and submarine fans

• Deep Basin >12 kPa/m

• 60-80 ⁰C

3. Swan-Elmworth

• Rich Gas

• Distal Offshore including turbidites and submarine fans

• Deep Basin 10-12 kPa/m

• 80-100 ⁰C

4. Stoddart

• Oil

• Distal Offshore including turbidites and submarine fans

• 10-12 kPa/m

• <60 ⁰C

Montney EURs

• CDL has forecast EURs for each Montney producer

• A type curve is appended to the last stable production from each well

• Forecast is run out to terminal rate

• Highlights areas of best expected performance

Company F’s costs were 58% higher, They can expect recovery 4.7 times greater.

Actionable Analysis

Rigorous type curve development and reliable EUR data combined with detailed completion information provides operators with parameters to adjust programs and materially improve results.
