Sand Management

According to the US Energy Information Administration, West Texas Intermediate (WTI) annual average oil prices have fluctuated between $93.2 and $43.3/bbl between 2014 and 2019. The price was $76.4/bbl (WTI spot price) at the beginning of October 2018, dropping approximately 41% to $45.4/bbl on 1 January 2019, reached a peak of $66.3/bbl on 23 April 2019, and then depressed to today’s (15 August 2019) $55.1/bbl.

The lower and unstable oil prices since 2015 have continuously pushed operators and service companies to reduce costs and improve capital efficiency in all aspects of business, including sand management. This is reflective of the industry’s attention on fundamental and proven sand-control practices. This year, many published works have focused on standalone screens as the most cost-effective solution when compared with other more-expensive approaches such as gravel packing or frac packing. Screens are reliable for sand control when properly designed and used in suitable sand-prone environments. The latest technologies in this area have featured developments focusing on mitigating plugging and erosional damage.

While sand control in production wells catches much attention, water-injection wells also are subject to sand-control problems triggered by water hammer, crossflow, and backflow. Newly developed screens for water-injection wells have been demonstrated with promising results in the latest field trials in preventing formation sand from flowing back and, therefore, maximizing injectivity.

In this issue, I have selected a variety of papers with more emphasis on cost-effective sand-management practices and operations. Please read the following three paper synopses with the recommended additional readings for more information, and do not forget to attend the upcoming SPE Annual Technical Conference and Exhibition scheduled for 30 September through 2 October in Calgary.
