...Greg Stephenson Technology Focus Since I began writing this feature 2 years ago, I have purposely avoided discussing the elephant in the room, but it seems that now the time is right to give the topic its due. Just as the unconventional revolution has transformed our industry during the past decade...

...Martin Rylance Technology Focus Measured-pressure approaches (drilling, cementing, and completions) have offered much promise for some time but have been slow to reach widespread application. A spate of technical developments, deployments, trials, and applications, however, recently has pushed...

...William Bailey Technology Focus The original realm of this Technology Focus was reservoir simulation, but the scope has been expanded to include all simulation. This is, indeed, a broad sweep, and I fear that I may not be able to do full justice to technical domains in which I am not fully...

...Simon Chipperfield Technology Focus The charge of a JPT Technology Focus reviewer is not only to select the best SPE papers encountered over the past year but also to identify potential ways in which these papers, and the technology contained therein, can assist the growth of industry professionals...

...Sunil Kokal Technology Focus In my last two Technology Focus columns, I discussed CO 2 -enhanced oil recovery (EOR) and the challenges it faces in conventional oil reservoirs. In this entry, my focus is on its applications in unconventional reservoirs. Oil and gas production from unconventional...

...Frank Chang Technology Focus The fourth industrial revolution is taking the oil and gas business by storm. Many companies have increased resources for developing and using big-data analytics and machine learning to catch the wind that could bring the fragrance of the new economy. In a conversation...

...Stephen Goodyear Technology Focus In the March edition of JPT , a series of articles looked at professional pride. Reading them made me reflect on my own career and consider what have been my best moments in the industry (to date!). Back in the 1990s, I was part of an EOR group providing technical...

...Alex Crabtree Technology Focus During the past several years, lean philosophies, methods, and techniques have been applied steadily and increasingly within the upstream segment of the oil and gas industry. Perhaps one of the more notable areas for this growth has been in unconventional well...

...Zillur Rahim Technology Focus As gas development focuses more on tight and ultratight formations, the challenges to produce economically become diverse and more intense. One main challenge faced while fracturing a well is a high fracture gradient. This can be caused by near-wellbore tortuosity...

...Bernt S. Aadnøy Technology Focus When students ask me about the most important way to maximize recovery, my answer is long directional wells. These wells have revolutionized the oil industry and are drilled under conditions never imaginable years ago. One outstanding example is the Troll field...

...Gunnar DeBruijn Technology Focus Cementing and zonal isolation are critical through the life cycle of the well. As I read through the cementing papers that were presented this year, I observed discussions on cementing and zonal isolation during drilling, completion, and abandonment activities. I am...

...Morten Iversen Technology Focus Deepwater capital expenditure has nose-dived since the oil-price crash of 2014 and has not quite recovered because of the high level of breakeven prices required, but some oil companies maintained their interest in the sector and went ahead with big-ticket projects...

...John Hudson Technology Focus When I was a chemical engineering student, my cohort joked about the relative merits of McCabe-Thiele and Ponchon-Savarit (graphical distillation design methods) and which of these they liked better. Perhaps as a petroleum engineering student, you did the same...

...Doug Lehr Technology Focus Are You There Yet? For the optimal completion system, does “there” mean customization, standardization, or component modularity? Does it mean maximum reservoir contact or maximum surface contact? More or fewer clusters? Does it mean a completion that uses many...

...Alexandre Emerick Technology Focus Machine-learning methods have gained tremendous attention in the last decade. These methods are tackling and solving complex problems with impressive results in many different areas. Buzzwords such as “big data” and “deep learning” are now part of our everyday...

...Ehsaan Ahmad Nasir Technology Focus To cater to the seasonal highs and lows in demand throughout a year, natural gas is stored in underground storage facilities. The need for such facilities arose because increasing (or decreasing) gas production to mirror changes in demand is neither practical nor...
