The difficulty in applying traditional reservoir-simulation and -modeling techniques for unconventional-reservoir forecasting is often related to the systematic time variations in production-decline rates. This paper proposes a nonparametric statistical approach to resolve this difficulty. In this work, the authors perform automatic decline analysis on Marcellus Shale gas wells and predict ultimate recovery for each well.
Decisions in E&P ventures are affected by Bias, Blindness, and Illusions (BBI) which permeate our analyses, interpretations and decisions. This one-day course examines the influence of these cognitive pitfalls and presents techniques that can be used to mitigate their impact. Bias refers to errors in thinking whereby interpretations and judgments are drawn in an illogical fashion. Blindness is the condition where we fail to see an unexpected event in plain sight. Illusions refer to misleading beliefs based on a false impression of reality. All three can lead to poor decisions regarding which work to undertake, what issues to focus on, and whether to forge ahead or walk away from a project. Strategic thinking and planning are key elements in an organisation’s journey to maximise value to shareholders, customers, and employees. Through this workshop, attendees will go through the different processes involved in strategic planning including the elements of organisational SWOT, business scenario and options development, elaboration of strategic options and communication to stakeholders. Examples are provided including corporate, business unit and department case studies. This seminar will teach participants how to identify, evaluate, and quantify risk and uncertainty in everyday oil and gas economic situations. It reviews the development of pragmatic tools, methods, and understandings for professionals that are applicable to companies of all sizes. The seminar also briefly reviews statistics, the relationship between risk and return, and hedging and future markets.
The current presentation date and time shown is a TENTATIVE schedule. The final/confirmed presentation schedule will be notified/available middle of October 2019. If we have learned anything from the North American experience, unconventional resources cannot be exploited by small incremental projects. If we are to be successful in developing these types of reservoirs, we have to make project scale operations work to bring these resources to market in a timely manner. A number of Eastern Hemisphere unconventional gas projects have raised interest, neared completion or are commencing deliveries.
On September 13, the Delaware River Basin Commission voted to begin the process to ban hydraulic fracturing near the river to protect the drinking water of 15 million people. A 7-year moratorium on natural gas development near the Delaware River would be replaced by a permanent ban under a proposal that’s being developed by the agency that oversees the water supply of more than 15 million people.
A professor, whom the EPA charged with reviewing its 2016 study on hydraulic fracturing’s possible effects on drinking water, shared her observations on the process that led to the agency’s final conclusion. On September 13, the Delaware River Basin Commission voted to begin the process to ban hydraulic fracturing near the river to protect the drinking water of 15 million people.
The combination will operate and share ownership of midstream gas assets in the Utica and Marcellus Shale plays. CPPIB financially backs operator Encino Energy, which last year acquired Chesapeake Energy’s Utica assets. The high level of dissolved iron commonly present in the Marcellus waters of Pennsylvania and West Virginia adversely affects the ability of scale inhibitor to inhibit calcium carbonate scale.
When methane is found in water wells near an unconventional well, fingers point to fracturing as the likely suspect. But a study of wells in the Utica Shale named other sources. The Texas Supreme Court ruled late in April that the Railroad Commission of Texas, the state’s oil and gas regulator, does not have exclusive jurisdiction over environmental contamination cases, which can be settled in court.
A recent study found that female mice exposed during prenatal development to chemicals used in unconventional oil and gas operations had abnormal mammary glands in adulthood. A professor, whom the EPA charged with reviewing its 2016 study on hydraulic fracturing’s possible effects on drinking water, shared her observations on the process that led to the agency’s final conclusion.

The oil industry will be able to draw water from the Little Missouri State Scenic River for hydraulic fracturing after North Dakota officials lifted an 8-week-old moratorium on industrial water permits, raising concerns from some conservationists about the effect on the Badlands.
A producer in the Marcellus Basin selected Edge Gathering Virtual Pipelines 2 to capture and liquefy gas from its stranded wells in Tioga County. Initial operation is underway and is set to be ongoing until at least 2022. Researchers at Texas Tech University have released a study into wastewater production and disposal in the Marcellus Shale, proposing disposal hubs across the state of Pennsylvania that could reduce trucking distances. As part of a revised strategic plan, the Spanish company says it will invest more than $9 billion on its overall operations by 2020, with much of it going to its upstream business unit. Predictive models may help in the estimation of produced water volumes and the optimization of the locations for water recycling and disposal facilities to reduce truck hauling distances.
Please take 5 minutes to give us your feedback on JPT and the technical topics of interest to you. Due to the impacts of the COVID-19 pandemic, the SPE and SEG will host the event in Houston, Texas. Denbury Resources needs enhanced debt reduction. The company that does enhanced oil recovery using carbon dioxide it produces and transports has skipped a payment to creditors while it seeks a deal that would reduce its debts. An independent study pegged the cost of the project at about $2.6 billion, 80% of which Norway’s government planned to fund.
