The Gulf of Mexico, and more precisely the Wilcox trend, has long been considered as challenging area for developing profitable hydrocarbon fields. In fact, the safe drilling of deep offshore wells needs to take into account the geological and geomechanical complexities, generated by the different sedimentological and tectonic events that accompanied the development of the Wilcox trend. In the case of Buckskin field, located in Keathley Canyon protraction (Figure 1), and in order to overcome those challenges, we developed a workflow that ranks all the parameters related to the geometry, the geology, the rock quality and the geomechanics characteristics of the reservoir. The core of the workflow is articulated around a probabilistic method that will assess the uncertainty of the productivity index, based on experimental design and Monte Carlo simulation. The proposed workflow allowed the optimization of the PI of the well thanks to a highly deviated reservoir section at a depth below 24,000', combined with an optimal fracking job.
Murphy Oil to Buy Deepwater US Gulf Assets for up to $1.625 Billion The El Dorado, Arkansas-based Murphy has quickly found a home for some of the cash it will receive from the sale of its Malaysia business. The company has been rapidly expanding its US gulf footprint while simplifying its portfolio and targeting more oil. The pact, which builds on the firms’ current partnership on the Buckskin project, covers four Keathley Canyon blocks including the Leon and Moccasin discoveries. BP announced four discoveries in the Gulf of Mexico near existing platforms. It use advanced seismic imaging to identify resources in deepwater locations that can be developed cost effectively using platforms nearby.
Phase 1 production from the deepwater US Gulf of Mexico field is expected to reach 30,000 BOPD. The field contains an estimated 5 billion bbl of oil in place. LLOG’s subsea pipeline tiebacks and structures connecting the Stonefly development to the Ram Powell platform are scheduled to be installed in Q3 2019.
Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253. Operator Talos Energy now believes Zama’s gross recoverable resource lies in the upper half of its pre-appraisal estimate of 400–800 million BOE. The consortium is working toward a 2020 final investment decision on the project. The deal consists of stakes in nine shallow-water producing fields covering 108,000 gross acres in 10–50 m of water. The new well control rule is evidence that memories of the Macondo blowout remain a powerful force for caution.
The firms are now partners on multiple blocks in the North Argentina Basin. Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253. Production from the Hibernia platform was shut down again on 17 August after its second oil spill in a month, while Husky Energy began to ramp up output from the White Rose field following the largest-ever spill off Canada’s easternmost province. The discovery marks London-based Tullow’s first operated contribution to a long list of discoveries since 2015 in the emerging petroleum province. Anchored by the Khaleesi-Mormont and Samurai fields, the King’s Quay FPS will receive and process up to 80,000 B/D of crude oil.
Phase 1 production from the deepwater US Gulf of Mexico field is expected to reach 30,000 BOPD. The field contains an estimated 5 billion bbl of oil in place. After suffering major setbacks, Chevron’s massive Big Foot project finally achieved first oil last November in the US Gulf of Mexico. With the setbacks in the rear-view mirror, project personnel spoke about the challenges. BP and partners have sanctioned the Azeri Central East project, the next stage of development of the giant Azeri-Chirag-Deepwater Gunashli oilfield complex in the Azerbaijan sector of the Caspian Sea.
The subsea tieback is expected to start up in 2021. This is Shell’s second major development on a tieback in the US Gulf of Mexico, following Kaikias’ startup in May. The Bureau of Safety and Environmental Enforcement reported about 14% of oil production and about 14% of natural gas production remains shut in following Tropical Storm Barry. Offshore personnel are reboarding Gulf of Mexico platforms, oil and gas production begins recovery. Operators' reports of evacuated personnel remain unchanged from yesterday.

Is Optical Gas Imaging the New Solution for Methane Detection? Thermal imaging helps operators maintain regulatory compliance on methane-emissions requirements. Optical gas imaging technology may be an answer in allowing for faster, more efficient inspections, but there are hurdles to its adoption. How can its widespread use become a reality?

In a $60 to $70 oil environment, the subsea market is poised to grow around 7% annually up to 2025. But a significant portion of this activity is at risk if the price of Brent crude falls to $50 per barrel. The subsea operations company said its most recent campaign is the first fully unmanned offshore pipeline inspection completed “over the horizon,” surveying up to 100 km from the shore. One of the largest industrial projects in the UK in recent years, Mariner marks Equinor’s first operated field on the UK Continental Shelf. It is expected to produce 70,000 BOPD at peak rates.
