shut-ins
-
Based on the early results from mass shut-ins of shale wells, it did not harm long-term production and it paid a short-term dividend with more oil flowing in the days after restarting. -
Oil sands producers predicted they could reduce production by 300,000 B/D by turning down steam injection. This will test methods to reduce, rather than stop, injection to avoid the damage caused by rapid cooling in some wells.
-
When oil demand vaporized, oil sands producers cut 300,000 B/D of production from wells using steam injection to produce bitumen. It is a huge test of something they have long been reluctant to do—turn down in-situ production when prices plunge. -
The good news is 95% of the oil companies in Texas are expected to survive 2020, which means there is a lot of bad news to endure.
-
The Permian Basin is now influencing the upstream water market on the way down, while many questions swirl around the implications of unprecedented shut-ins.
-
New commentary from the SPE Reservoir Advisory Committee (RAC) provides key high-level insights on the potential consequences of long-term shut-ins on conventional and unconventional reservoirs.
-
The silver lining for those overseeing the unprecedented shut ins of tight-oil wells is the potential to acquire a wealth of reservoir data. But first, petroleum engineers need to monitor these wells and use the right analysis toolbox.
-
The industry has very limited experience in shuttering production on a large scale in unconventional reservoirs. Many questions remain on how stimulated, nanodarcy shale reservoirs may respond. George King discusses the paradigm shifts needed in the industry.
-
A technical synopsis of major considerations for unconventional wells facing prolonged shut-ins. The review includes deciding factors for kill fluid selection and risks of incompatible fluid mixing.
-
As tight-oil producers move to curtail production, hard-to-answer questions are being raised about how shuttered wells will come back. The issue reveals key uncertainties about the delicate flow paths that define unconventional reservoirs.
-
Oil companies are considering whether shutting in a well for a month or so may mean stronger production later by allowing more time for water to soak into the rock, which gets it out of the way of the oil and gas. But this is not always effective, and additional work is needed.
