The chart shows US Lower 48 gas well connections for four regions: Appalachia, Rockies, Mid Continent & Permian, and GOM & Gulf Coast.

The chart shows rig count forecast in the main producing areas.

Appalachian gas production is predominately lower-cost development from the Marcellus and Utica shales. Appalachia’s rig count dropped significantly in 2015–2016.

US Gulf Coast (USGC) and Gulf of Mexico (GOM) gas production is a mix of conventional (mostly offshore) and unconventional onshore (tight and shale gas) as shown on the map. The USGC includes the South Texas region with liquids-rich Eagle Ford shale gas and East Texas/North Louisiana (ET/NL), which includes Haynesville shale gas.

The map shows new gas well initial productivity distribution for Eagle Ford.

The map shows new gas well initial productivity distribution in Haynesville.

The Rockies region consists of the Green River, Piceance, Uinta, Powder River, and San Juan basins.

Figure shows dry gas production change between 2005–2016 and 2017–2030. Green represents low full cycle cost, yellow represents average full cycle cost, and red represents high cost.

Chart on left shows all Marcellus well IPs.

• Plays are not homogeneous.
• IPs range from 1 MMcf/d to 16⁺ MMcf/d (dark red dots).
• Most productive areas are drilled first as they will generate highest producer returns.
• As highest productivity areas are exhausted, less productive and higher-cost areas are targeted.
• Solomon’s supply forecast methodology:
  • Historical well data are collected, filtered and formatted to ensure quality and consistency. Then, estimated ultimate recovery (EUR) is calculated for each well using traditional decline analysis. In each basin, all wells are plotted in a map based on their initial productivity (IP) or EUR. A contour is used to group wells into ranges based on their IP. These groups of IP/EUR ranges are called bins. Accordingly, the total area associated with different bins is estimated. After that, GIS analysis and data reported by producers (lateral length, frac width, etc.) are used to calculate well spacing for each bin. The number of potential drilling locations in a bin is estimated from the total bin area divided by the area per well. Total resources per bin is then obtained by multiplying well EUR by the number of drilling locations for that particular bin. There is a full cycle cost associated with each bin calculated per unit of production. Thus, areas with higher productivity within a play will have lower full cycle cost.

Chart shows the steps to put a well on production (adding to gas supply):

• Start drilling a well (spud)
• Finish drilling (rig release)
• Completing the well
• Connecting the well to a gas plant via a gathering pipeline system

Technology revolution is an important lever; however, its impact on costs has been masked by the large effect of reserve size changes and cost inflation. Figure shows some changes of this decade including:

• Exploration – High frequency seismic with seismic processing, natural fracture identification by seismic.
• Drilling – Coiled tubing and top drive rigs, horizontal and multilateral wells, multi-well locations, multi-well pads and programs, real-time data, geo-steering with near bit sensors, under-balanced drilling, slim hole wells, monobore wells/expandable casing & tubulars, new bit designs, high pressure & high temperature wells, and automation (such as pipe handling).
• Completions – Multi-zone completions, optimized, standardized programs, non-damaging low polymer fluids, ceramic proppants, micro-seismic for fracture propagation detection, re-fracturing, re-completions, soak time.
• Production – Automated controls, remote well telemetry, optimizing well spacing and production, choke initial production increases EUR.
• Pipelines – Smart pigs, high pressure pipe, improved compressor efficiency.

1. DEWATER/DEPRESSURE: Water is pumped from the fracture and cleat system in the coal.
2. DESORPTION: Coal formation pressure falls, natural gas, which is absorbed on the surface of organic material, is desorbed from the organics and diffuses through the coal to the cleat and fracture system.
3. GAS FLOW: As more water is pumped out, more gas and less water are produced.
4. With further gas production, the rate of desorption falls (less gas remains absorbed on the surface of the organic material) and gas production falls.
5. Water production and disposal is expensive, lower cost (shale) gas is being developed; CBM production is declining.

The chart provides our forecast for East Coast gas production.

Alaska

• Alaska Government in 2007 approved the proposal submitted by TransCanada Pipeline (TCPL) under the Alaska Gasline Inducement Act (AGIA). Gas would be transported to Alberta and tied-in to the TCPL system & includes an option to build a line to transport gas to Valdez for LNG.
• Decision made in 2014 that the pipeline project to Alberta was not economical.
• Alaska Gasline Development Corporation (AGDC) signed agreement with BP PLC and ExxonMobil to help advance the 43.4B USD LNG project to be built in Nikiski on the Kenai Peninsula south of Anchorage. This project includes the construction of a 1,300 km pipeline from the North Slope.

Mackenzie Delta

• Mackenzie Valley Pipeline designed for 1.2 Bcf/d.
• Cost details: pipeline, field development & gathering system, gas plant & liquids pipeline.
• March 11, 2011 – NEB issued a certificate of public convenience and necessity following federal cabinet approval.
• Dead, a victim of the technology revolution.

• Many plays have been evaluated; few plays live up to early promise and quietly drop off the radar.

Anadarko basin has liquids-rich gas, mostly in southern portion of the basin, and tight oil and the north.

• Hydrates are solid, crystalline, ice like substances containing methane/water with methane trapped in in a water-ice lattice.
• Form under moderately high pressure at temperatures near freezing, in permafrost areas, sea bottom or under seabed.
• Shows data for US and Canada only.

The chart shows Western Canada gas production to 2030 by gas type and the growth needed to meet LNG export demand.

Montney tight-gas production will continue to grow as evaluation and development continue, expanding after 2022, when gas supply will be needed for LNG export markets.

Montney is a tight-gas play with lateral facies variations of fine-grained sedimentary rocks leading to areas of non-commercial, low-gas-rate production.

The chart shows gas well connections to 2030. Well connections peaked at more than 18,000 in 2006 and declined significantly thereafter as gas prices plummeted and producers increased high-productivity horizontal well drilling.

The chart shows the average new gas well IP in Western Canada to 2030.

The figure shows the location of the Deep Basin tight-gas plays in Western Canada as well as the dry-gas production forecast for Notikewin-Falher, Wilrich, and Spirit River. Production from these formations uses the same technology that is used in Montney and Duvernay development: multi-well pads, horizontal drilling, and multi-stage fracing.

Producers have focused on developing the northern portion of the condensate-rich sweet-gas play, which has one of the lowest break-even gas prices in North America due to significant NGL uplift. Development of the southern area (Willesden Green) started a few years ago. Duvernay East area is an oil play with high associated-gas content.

The chart shows Western Canadian dry-gas production per play. In 2030, most production will come from Montney BC.

The figure illustrates Solomon assessment of Duvernay NGL yield distribution based on well and processing plant data allocated to the particular wells.

The figure shows locations of wells drilled in 2018 in Western Canada. Almost all wells were drilled in Montney, Duvernay, and Deep Basin Cretaceous.

The chart shows Montney and Duvernay well connection forecast to 2030.

The figure shows dry gas production for major US gas basins to 2030. The solid blue area represents production from gas wells drilled before 2018; the hatched blue is Solomon‘s forecast of production. In 2018, US natural gas production growth and development is primarily focused in three basins: Marcellus, Utica, and Haynesville.

The chart shows North American dry gas production to 2030 by gas type: Associated (Solution), Conventional, Coalbed Methane (CBM), and Shale & Tight Gas.

• North American gas supply is demand driven.
• North American gas supply mix is “Unconventional” Gas—the new conventional gas.
• Higher-cost conventional gas production will continue to decline.
• Shale and tight gas growth will come mostly from liquids-rich areas of Utica, Marcellus, Haynesville, Montney, and Duvernay.
• Associated gas will increase mainly because of the growth of tight oil production in Permian, as well as in Bakken, Eagle Ford, and Niobrara.

Solomon calculates initial productivity (IP) as the average of raw gas peak month production for all gas wells per basin.

The figure shows average initial raw gas productivity of gas wells since 2010; dark-red bars are history, red bars are Solomon‘s forecast.

In this low-price capital-constrained environment, producers drill only the best (i.e., highest productivity wells), so IP increases.

The figure shows the rig count over the forecast period (2018–2030).

• Appalachia’s rig count dropped significantly in 2015–2016 due to low regional gas prices and pipeline and processing infrastructure constraints. Also, due to significant improvements in well productivity and reduced drilling times, fewer wells are required to sustain or increase production.
• Haynesville rig count started to climb in 2016. Eagle Ford gas rig count also increased starting the fourth quarter of 2017. The total rig count will continue to grow during the forecast period mostly due to increased drilling in Haynesville.
• The Mid Continent and Permian region shows a stable rig count during the forecast period. Currently, there is only one rig operating in Fayetteville, three rigs in Barnett, and six rigs in Arkoma Woodford. There is no new gas drilling in Granite Wash and Woodford Cana.

The figure presents the supply-demand balance for the Appalachia region. Overall demand growth (2.0% per year) is expected to be outstripped by supply (7.3% per year), creating a need to move excess supply to regions outside of the US Northeast.

• The North American pipeline grid is interconnected and responsive to changes in Henry Hub pricing.
• In 2017, the region had net outflows of natural gas on an annual basis.
• Marcellus and Utica gas will continue to grow, backing out Rockies, Western Canadian, and US Southwest gas supply.
• As infrastructure enhancements are completed, excess supply will look to flow to high-value LNG markets* and those markets along the eastern seaboard.
• Gulf Coast and Midwest markets will provide the least value for Appalachian natural gas supply in excess of demand.

*Cove Point in Maryland shipped its first LNG export cargo in March 2018.

The figure shows the variation in dry non-associated gas production trends between strategy areas, the forecast for dry-gas production to 2025 based on gas demand, Deep basin strategies in BC and Alberta will remain the fastest growing production areas in Western Canada.

Central Alberta, Southern Shallow, and Northern gas production will continue declining, with limited development of mature, high-cost conventional gas, and coal bed methane (CBM).

The figure illustrates Solomon’s assessment of the Duvernay natural gas resource geographic distribution using initial well productivities (IPs). Average Duvernay well dry-gas initial productivity in 2017 was 2.2 MMcf/d.

Solomon maintains proprietary models for key plays and basins in North America which are used to forecast annual average production based on:

• Allocation of aggregate demand for natural gas to the regions with the lowest relative gas supply cost first then the next lowest cost using gas resource-cost curves bearing in mind that producers will continue drilling to keep their infrastructure full (or optimized) and to fulfill contractual obligations.
• Drilling and completion activity trends considering availability of cash flow for capital investment, NGL content, play maturity (well density and remaining potential resource) and availability of equipment.
• New well initial productivity (IP); projected from recent trends and linked to Solomon’s gas resource mapping, considering play maturity.
• Production decline rates are applied to new and existing wells considering the age of the wells.

The models generate a raw-gas production forecast, which is converted to dry gas using shrinkage factors calculated from public sources and previous Solomon analyses.

This figure illustrates Solomon’s view of the distribution of North American ultimate potential natural gas resources subdivided by region and by break-even gas price. The size of the pie area corresponds with the regions’ ultimate natural gas resource potential. Ultimate potential resource is the amount of resource that is thought to be technically recoverable, without regard to the economics of extraction.

This figure shows Estimated Ultimate Recovery (EUR, measured in Bcf per well) for major North American Gas Basins in 2010, 2017, and 2025.

• Western Canada Conventional EUR on an average basis is very low, which makes the unit cost of adding reserves very high.
• The bright spot in Western Canada is the Montney tight-gas play in the NGL-rich part of the play.
• Appalachian EUR includes the Marcellus Shale; East Texas, North Louisiana EUR includes the Haynesville Shale; GoM Coast EUR includes the Eagle Ford Shale. 

This figure shows a schematic cross-section of the Ultra-Deep play and a map showing its relation to the Deepwater plays.

• The Deep Shelf lies more than 15,000 feet below the outer continental shelf, in water depths ranging to 1,000 feet.
• Much of the Deep Shelf could access existing Shelf infrastructure, saving development costs.
• The region is mature with today’s technology—3D seismic has been very successful in delineating shallower prospects, and production has declined since 2002.
• Potential remains for the pre-Miocene (productive onshore and in Deepwater) of the Ultra Deep Shelf (20,000 to 30,000+ feet), as demonstrated by McMoRan’s Davy Jones discovery.
• Advanced drilling technology is needed for these high-pressure, high-temperature Ultra Deep wells, which can cost over 100MM USD.

This figure shows the relative areal extent of key US shale plays; the Utica is a little smaller than the Marcellus. Note: The maps are sized to the same distance scale.

• Maps show initial productivities (IPs) used in Solomon’s production forecasting.
• The highest gas well productivity is shown in red, the lowest in dark blue.
• Wells are ranked based on their IPs; polygons with different ranges of initial productivity are generated; and the area of each polygon is calculated.
• Well density is calculated for each basin and each range of IP.
• Well connection forecasts are constrained by well density and maximum number for each range of IP.

This figure illustrates the hydrocarbon distribution in the Montney play ranging from dry gas (blue) to the southwest and oil (olive green) to the northeast. The figure also identifies the three core areas—BC North, BC South, and Alberta—which are further subdivided based on the hydrocarbon type.

• Condensate: over 80 bbl/MMcf
• Rich: 25–80 bbl/MMcf
• Wet: 10–25 bbl/MMcf
• Dry: less than 10 bbl/MMcf

Tight gas is not defined in Canada; Solomon defines it as:

• Laterally continuous, generally thick sands, conglomerates, and carbonates with low matrix permeability.
• Saturated with sweet gas and often liquids rich.
• Includes Greater Sierra (Jean-Marie) and the extended Deep Basin.
• Excludes Eastern shallow gas and the Foothills.
• Consistent need for large fracture stimulation to connect pore space to the well bore.
• Jean-Marie peaked at 520 MMcf/d in 2004; wells commonly horizontal and underbalanced.

Extended Deep Basin

• A thick section of Mesozoic low-permeability sands and conglomerates.
• Economics are improved by natural gas liquids (NGLs), using existing infrastructure, and commingling production.

• The two key technology advances for unconventional gas (and oil) are horizontal drilling and fracturing.
• Horizontal wells rapidly became the majority of gas wells drilled. The well is drilled vertically, but then, at the producing zone, the drill bit is steered until the well bore is horizontal. Drilling continues horizontally until the end of the well is reached. The horizontal section can be up to 5,000 ft long, and a number of horizontal sections may be drilled from the same vertical well.
• Horizontal wells increase the reservoir volume, which is in contact with the well so the well will produce at higher rates. Though horizontal wells cost more to drill than vertical ones, the higher cost is usually more than offset by the higher production. Pad drilling—multiple wells drilled from a single surface location—reduces the environmental footprint and costs.
• The figure presents a horizontal well schematic and the multi-stage hydraulic fracture stimulation that have been key to surging Shale Gas production and the growth of some Tight Gas plays. Each of the eight frac stages depicted in the figure is carried out sequentially, starting with the one furthest from the vertical part of the wellbore. Now over 2 dozen fracs can be done. The flow from an unconventional well mainly reflects the money invested in fraccing, not a natural flow rate, so we refer to it as a “manufactured” well. The initial rate is high, but drops off.
