A step change is noticeable in the quality of papers from the previous 2 years. First, the papers have better technical content; second, they are pushing the boundaries of currently accepted technologies and mores. Perhaps this is because of a desire to produce from ever-more-difficult and -challenging wells. The current energy crisis and higher prices as a result have encouraged the application of new technology, which, in a low-energy-price environment, generally takes a back seat. This is a good thing for the technology junkies of this world.
A few technology areas are worth mentioning. Although ceramic sand screens have been around for a few years, this year there were more than the usual number of papers on this technology. For those interested in probing the operating limits and life span of these screens, paper OTC 31896 is worth reading.
Sand consolidation continues to be a subject of interest, perhaps because of its noninvasive nature. Besides, it is potentially low-cost and has been used widely with success. This year, there were 10 papers on the subject. An interesting paper worthy of mention is SPE 208808, which introduces a novel temperature-activated, “green” consolidation fluid.
In paper SPE 207193, the authors propose a fast and accurate machine-learning algorithm to predict the onset of sanding in sandstone formations. The algorithm uses 11 geological and reservoir parameters that directly affect sand production. The answer is binary (i.e., sand production will or will not occur). This could be a great tool for completion engineers.
Finally, there was extensive coverage of sand management in the topsides, an area often overlooked. This trend is encouraging. Paper OTC 31554 is thought-provoking. It discusses the first field installation of a patented device that modifies the flow profile to alleviate the impact of solids at critical points.
I hope you enjoy the papers.
