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.
The new numbers for the Marcellus Shale and Point Pleasant-Utica Shale represent large increases from previous USGS assessments of both formations. Production and proved reserves in the Permian Basin’s Wolfcamp Shale and Bone Spring Formation are reaching new heights, and a new assessment from the US Geological Survey indicates the industry is just scratching the subsurface when it comes to what may be technically recoverable. Major oil discoveries by Armstrong Oil & Gas and ConocoPhillips have compelled the US Department of the Interior to reassess its estimate of undiscovered, technically recoverable resources in parts of Alaska. 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.
The new numbers for the Marcellus Shale and Point Pleasant-Utica Shale represent large increases from previous USGS assessments of both formations. A fracturing test site in West Virginia has quietly made a data trove available on the website of the Marcellus Shale Energy and Environment Lab. A drilling team has focused on increasing lateral lengths in the Marcellus Shale. The team determined which operational practices would need to be revised in order to drill and case laterals in excess of 18,000 ft. In this work, the authors perform automatic decline analysis on Marcellus Shale gas wells and predict ultimate recovery for each well.
This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained. This paper presents the design considerations, methodology, and results of two deepwater MPC operations conducted to cement production casing strings within a target operating window of approximately three-tenths of a pound. This paper presents lessons learned regarding design, testing, and installation of a completely integrated managed-pressure-drilling (MPD) control system on a deepwater drilling rig. This work focuses on the development of specific methodologies to support managed-pressure-dilling (MPD) operations implemented on real-time diagnostic software. This paper describes challenges faced in a company’s first deepwater asset in Malaysia and the methods used to overcome these issues in the planning stage.
New report offers guidelines for pressure pumpers of the future. A 3-year study of air quality, soils, groundwater, and waterways found few to no effects as a result of hydraulic fracturing operations in Surat Basin coal seam formations. Not everybody suffers when US oil producers slash production. Among the beneficiaries could be US gas producers who will benefit because less oil production will mean a lot less gas on the US market. A downhole compressor solution based on advanced magnetic technologies completed its first field trials in an unconventional gas well.
What Damage Is Wrought by the Rush to Shut In Wells? 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. Country had hoped to boost oil output and bring in much-needed revenues. This paper describes a coiled tubing gas lift (CTGL) technique successfully used to restart production from two pilot wells in a mature field in Pakistan that had been shut in since 2015. But the flow of ideas continues.
The merged companies will offer large-diameter coiled-tubing, directional drilling, snubbing, wireline services, and pressure pumping services. The amount of uncertainty related to directional drilling makes accurate drilling challenging, leaving much to human know-how and interpretation. Additionally, few path-planning methods in the literature consider the directional steering tool being used. This paper describes the analysis of sidetracks drilled in an open hole by an annular ledge formation method with a downhole motor in multilateral wells. Although multilateral and long-reach wells are common, the technological development is not complete.
The complete paper discusses an advanced matrix-stimulation work flow that brings reliability and flexibility to the acidizing of tight carbonate water injectors and has delivered injectivity improvements tight carbonate onshore reservoirs in the Middle East. This paper describes a coiled tubing gas lift (CTGL) technique successfully used to restart production from two pilot wells in a mature field in Pakistan that had been shut in since 2015. Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run. The papers summarized in this year’s feature demonstrate the application and versatility of coiled-tubing-based solutions to different phases of a well’s lifecycle, from exploration through production and, finally, to abandonment.
To optimize decision-making, minimize risk, and create value, oil and gas companies can turn to liberated, contextualized data. For exploration or drilling, liberated, contextualized data can help the upstream industry make trustworthy decisions that save time and costs. For surveying, exploration, analytics, and a whole host of processes, liberated, contextualized data tailored to the environments of E&P subsurface will empower confidence, speed, reliability, agility, and most importantly, innovation. This is how Aker BP is doing it. This article highlights a technology that helped one operator add $120,000 to its incremental gas recovery.
Help us make JPT more relevant to you. Please take 5 minutes to give us your feedback. Lingering low oil prices are forcing Occidental to mark down the value of its oil and gas assets again, making the burden of its staggering debt look even greater. Designed to be a “living” map, it focuses on the largest fixed infrastructure for crude oil and refined products such as trunk pipelines, refineries, and storage facilities. 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.
