Innovative Remedial Sand Control: Maximising Barrel Output with Retrofit Techniques

Sand production continues to be a significant challenge in the oil and gas industry, especially as more output is derived from aging and mature fields. This issue often arises due to the failure of primary sand control measures or the onset of sand failure, which can be attributed to reservoir depletion and increased water production. Reservoir depletion reduces the formation pressure, leading to the destabilisation of sand grains within the reservoir rock. Concurrently, increased water production can exacerbate the problem by further weakening the formation and facilitating the movement of sand particles into the wellbore. To address sand production, operators typically manage it at the surface, implement downhole sand control measures, or use a combination of both strategies. Remedial solutions aim to minimise sand production while maintaining the productivity of existing wells. Furthermore, these solutions must be both cost-effective and reliable, ensuring minimal downtime and avoiding frequent retreatment or reinstallation. The selection and design of downhole sand control measures require meticulous consideration of reservoir characteristics, production conditions, and economic factors. Various downhole remedial solutions are available, including mechanical and chemical methods that can be deployed through existing well completions. Examples include through-tubing sand control, sand consolidation, and agglomeration techniques.

From this session, we can gain valuable insights into downhole remediation solutions, comprehensive overview of various techniques and strategies used to address sand production issues in the oil and gas industry covering Selection and Design Processes, Execution: Results Analysis, Sharing New Technologies and Case Histories.
