New section milling technology designed for restricted IDs restores access to leached area of cavern in highly abrasive Texas salt dome

The Stratton Ridge salt dome in Brazoria County, Texas, has been used extensively by the industry for brining operations and for the storage of liquid hydrocarbons, refined products and natural gas. The shape of the dome has been defined by several hundred oil and gas wells drilled over the top of this highly anomalous geologic diapir structure. Cavern operations at Stratton Ridge are known to have experienced multiple problems, including severe lost circulation while drilling through cap-rock, sheared well casings, corrosion, shifting and encountering hydrocarbon products that appear to have escaped from the storage cavern...

Fire on closely spaced six-well pad illustrates heightened need for well control risk mitigation in pad drilling

Efforts to help reduce environmental footprint, infrastructure and development costs have led to an increased use of pad drilling. However, the close proximity of wells in pad drilling increases the risk of more severe consequences during well control incidents. In the case of a burning well, both radiant and direct heat can potentially ignite adjacent wells, threatening both human life and equipment and detrimentally affecting the immediate environment. This article describes challenges and lessons learned from controlling a multiwell pad blowout...

Open-hole, multizone completions drive development of single-trip sand control technologies

As operators continue to drill deeper wells in more remote offshore locations, the traditional wait-and-see approach to sand control is no longer an option in many cases. Operators have recognized that a proactive strategy is needed, and many are actually installing sand control equipment during the well’s initial completion, rather than waiting to do so only when sand production becomes a problem...

New digital age may disrupt traditional business models

By Linda Hsieh, Managing Editor The length and severity of this downturn have triggered a lot of discussion around the industry’s business model. Much of the discussion has centered around revising the traditional dayrate model to incentivize performance, but do such bonus schemes go far enough?

From automation to robotics, from data analytics to artificial intelligence (AI) – every day new technologies are pushing the industry ever closer toward changes that could significantly disrupt the business model as we know it. Numerous other industries have already undergone such disruptions, typically with new-to-industry “disruptor” companies coming out on top. “Uber is the world’s largest taxi company, ...
