More Oil, More Water: How Produced Water Will Create Big Cost Problems for Shale Operators
If crude prices, rig counts, and tight oil production demonstrate a stronger upward trend in the months to come, US shale operators may find themselves with more produced water than they bargained for.
New Numbers Highlight Permian Bonanza
This week the US Geological Survey (USGS) reported that the Wolfcamp shale holds 20 billion bbl of technically recoverable oil. This builds on other active formations in the Permian Basin, where nearly half of US active rigs are operating.
Completion and Well-Spacing Optimization for Horizontal Wells in Pad Development
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.
The Role of Induced Unpropped Fractures in Unconventional Oil and Gas Wells
On the basis of production data, diagnostic methods, and field observations, it is becoming increasingly clear that induced unpropped fractures created during the hydraulic-fracturing operation play a critical role in determining the success of fracture treatments.
Abundant Supplies A Lingering Problem
Mass layoffs and rising bankruptcies haven't put an end to abundant supplies.
The Reason to Expect Prolonged USD 30–60/bbl Oil
A fairly stable set of conditions coalesce to make a strong reason to expect the oil price to range between USD 30/bbl to USD 60/bbl for the foreseeable future.
Shift Toward Permian Drives Rising Rig Count
The US rig count has inched up recently, and the driver has been the old reliable of onshore oil production, the Permian Basin. With surging production, the Permian is the only major US oil shale play to grow since crude prices began to fall.
Engineered Shale Completions Based on Common Drilling Data
In this study, the authors demonstrate a reliable, cost-effective methodology that empowers shale operators with reservoir data on every well.
Boosting Shale Fracability With Positive Ions
A long-time energy industry executive and chemical engineer has built a new water treatment system that he says can increase recovery rates from shale wells without using chemicals and will recycle all the water used in the process.
Drilling Slump in North Dakota Allows Rapid Flaring Reduction
The amount of natural gas flared has plunged in North Dakota, a region that has been the leader by far in gas wasted because gathering systems could not hook up the wells fast enough.
Upon Further Consideration, US Gas Reserves Look Bigger
The list of the biggest gas plays in the US is being revised as the US Geological Survey creates new estimates based on additional drilling results and available rock samples. New at Number 2 is the Mancos Shale on the Western Slope of the Rockies with 66 Tcf in recoverable reserves.
Shell Stays Committed to Shale Opportunities
Shell has reaffirmed its commitment to the shale business and views it as a growth opportunity moving into the 2020s
New-Frontier Reservoirs I
With the current changes in the industry, are we seeing the demise of unconventional developments? No, clearly not. The unconventional industry is adapting to deliver the energy demands of the future despite the low oil price.
CO2-Based Enhanced Oil Recovery From Unconventional Reservoirs
In this study, detailed petrophysical and geological field models focusing on the middle and lower members of the Bakken Formation were developed.
EOR-For-Shale Ideas to Boost Output Gain Traction
The low recovery rates observed in most shale reservoirs has prompted a number of research projects to develop new enhanced oil recovery methods.
DNA Sequencing: A New Diagnostic Tool for Shale Wells
For the past 2 decades, the use of DNA sequencing technology has largely been relegated to the domains of criminal forensics and the healthcare industry. One company is betting that the shale industry soon will join that list.
Unconventional Measures For Shale Reservoirs
One of the biggest ways to lower the cost of production from shale would be to identify zones that are productive, or not, before fracturing them.
Shale Completions Improve, Despite Shrinking Number of New Wells
Two places that illustrate the mounting challenges facing the shale business are the Bakken Shale in North Dakota, where the number of working rigs is one-third what it was a year ago, and the Fayetteville Shale in Arkansas, where there are no more working rigs.
Surviving the Downturn: Oil Executives See Continued Tough Times Ahead
Holding little back, speakers at the annual IHS CERAWeek conference in February discussed how the industry has been shaped by the disruptive impact of North American shale production and predicted that many more months of financial pressure will spell the end for some companies.
Drawdown Management Critical To Mitigating EUR Losses in Shale Wells
In drawdown management, operators can exert control over the downhole flow pressure, reservoir pressure, and choke size to avoid estimated ultimate recovery (EUR) losses.
Designing an Optimized Surfactant Flood in the Bakken
The Bakken’s ultratight, largely oil-wet nature limits the potential of waterflooding. As an alternative, an optimally spaced well-to-well surfactant-flooding technology is proposed.
Water Management: Lessons Learned and Considerations for a Shale Play in Argentina
This paper discusses aspects of water logistics necessary during the well-completion phase, fracture-treatment designs applied in Vaca Muerta, and laboratory studies performed on flowback and produced water to help evaluate the potential for water reuse.
Digitizing Core Scans Brings Old Methods into 21st Century
Pulled directly from the reservoir rock, core samples provide critical data used to determine how exploration should proceed. Until recently, core analysis remained old school, however, there is an ongoing transition to bring the process of core description into the digital age.
Halliburton Reveals Refracturing Strategy
Although refracturing is a topic that has gained a lot of interest, many shale producers have been sitting on the sidelines because early results did not justify the spending
A Practical Simulation Method Capturing Complex Hydraulic-Fracturing Physics
To understand production from shale reservoirs, the role of hydraulically induced fractures, natural fractures, and their interaction in a formation must be captured.
Artificial Lift Experts Warn of Long-Term Production Issues in Horizontal Wells
A panel of experts says US shale producers need to rethink their drilling and completion designs as problems mount for horizontal wells when they go on pump. Hanging in the balance is whether long-term production from many shale wells will be achievable.
