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.
In the complete paper, the authors revisit fundamental concepts of reservoir simulation in unconventional reservoirs and summarize several examples that form part of an archive of lessons learned. 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.
The complete paper presents a large-scale work flow designed to take a vast amount of data into consideration. The work flow can be scaled for projects of any size, depending on the data available. 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.
The complete paper discusses the use of cumulative production ratio curves normalized to a given reference volume in time for different unconventional plays in North America to investigate the median trend for each play and the median ultimate recovery per play. 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.
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.

The course begins with the understanding of fundamentals associated with unconventional resources, which includes shale as well as tight and CBM formations. The course then focuses on shale resources development with the understanding that the same principle, with some modification of the methodology, can be applied to other unconventional resources. The course takes a "life cycle approach to shale resources development starting with exploration, appraisal, and moving towards development and production. Then, it looks at technology and means to rejuvenate shale resource." Participants will become familiar with the associated technologies needed to develop the shale resource in each of the five phases.
