This paper provides perspective on the current state of multizone completion technology and issues encountered in the industry with developing a system that offers increased capabilities to meet the increasing challenges presented by the Lower Tertiary in the Gulf of Mexico. The lower tertiary formation found in the pre-salt layers of the Gulf of Mexico has become a proving ground for extending what is possible when completing multistage fracturing in ultradeepwater wells.
The Apollonia tight-gas chalk play is located in the Abu Gharadig Basin in the Western Desert of Egypt. This has long been ignored as a gas play in the overburden, while the Jurassic and Cretaceous oil fields deeper in the basin have been explored and developed. Large areas of the North Sea contain Cretaceous sediments, which form a massive hard layer of chalk that historically has presented a major drilling risk and expense to operators in the area.
Sourcing water for hydraulic fracturing, and disposing of produced water, are constraints and significant cost items in the Permian Basin. Some of the produced water can be treated and reused by using a water life cycle approach.. The $10-billion deal will add liquefaction and export capabilities to the existing facility in Sabine Pass, Texas, according to a Reuters report. Golden Pass currently handles up to 2 Bcf/D of natural gas imports to North American markets. A deal with the UK-based energy and chemicals company could fetch up to $3 billion for ConocoPhillips, which is transitioning out of the North Sea to focus on US shale operations.
Producers in Texas have claimed an economic victory with their transition to local sands that they once avoided using in horizontal wells due to their low-quality. Driven by a recovery in well completions and increased proppant loading per well, the market for raw fracturing sand is expected to grow by more than 4% annually through 2021, an industry research study says. Permian Basin producer Callon Petroleum is attributing its data-driven approach to a routine completions practice to improved proppant placement and higher oil production. Carbo Ceramics is making big strides in the use of ceramic proppant. Although Saudi Arabia has plenty of sand, it took some ingenuity by Saudi Aramco and Schlumberger to figure out how to use it effectively as proppant.
Unconventional development has made it clear to Erdal Ozkan that conventional theory overlooks a lot of potentially productive rock. He talks about looking for ways to do better as part of JPT’s tech director report. The industry has figured out how much opportunity lies in the Permian Basin’s Delaware subbasin, and the Delaware play is now dominating US unconventional oil activity, Citigroup’s Jeff Sieler told the SPE Gulf Coast Section reservoir group recently. Unconventional Resources: Will Shale Oil Ever Make Money? This well-established oilfield consultancy explains why 2020 might be a big year for the unconventional sector.
Another reminder that it costs more to coax the same amount of oil from new wells as for older wells nearby, with a closer look at the big plays and how the wells are completed. ProPetro closed its deal to purchase Pioneer’s pressure pumping fleet, boosting its services in the Permian Basin. How Close Is Too Close? The ideal well spacing is in the eye of the beholder. The decision depends on so many factors that machine learning is now trying to determine the best combination of ingredients.
Billion-dollar valuations for these companies in the near future could become a reality. Frac water disinfection experts become De Nora service arm in the unconventional oil and gas market. Three papers selected from 2018 SPE ATCE look at the challenges and approaches to the treatment of increasing volumes of produced water. Sourcing water for hydraulic fracturing, and disposing of produced water, are constraints and significant cost items in the Permian Basin. Some of the produced water can be treated and reused by using a water life cycle approach.. Water management for unconventional projects continues to evolve at a rapid pace.
After a long cooling off period, this dry-gas shale play is once again red hot. Ghawar vs. Permian Basin: Is There Even a Comparison? While some try to put the two enormous oil producers toe-to-toe, the best thing to do might be to understand why they are different. Machine-learning methods have gained tremendous attention in the last decade. The underlying idea behind machine learning is that computers can identify patterns and learn from data with minimal human intervention.
