Using Advanced Geomechanical Analysis to Define Practical Cut-offs for Sand Management Decisions
Includes a Live Event on 06/04/2020 at 9:00 AM (EDT)
This presentation demonstrates how a series of pragmatic cut-offs and decision support charts can be derived for credible sand management and completion selections. Sanding (or solids production) has multiple adverse effects on well productivity, integrity and can pose safety and environmental hazards. Sanding has a geomechanical root and it can be managed: “avoided; mitigated, controlled or handled”. An effective sand management strategy starts with the geomechanical characterisation of the target formations and sand production assessments. Once the field-calibrated geomechanical sand production prediction model has been established, using limited data such as a log-derived rock strength profile, decision flowcharts can be developed to assist well engineers for completion and sand control decisions by considering the well-life risk of sanding and borehole instabilities. Such decision charts enable well and production engineers to follow a quick, cost-effective and holistic approach for sanding assessment and completion selection. This contrasts with alternative methods, which can be either overly simplistic or excessively complex. Two case studies are presented which cover the development and use of practical cut-offs for real-time sanding assessments and completion selections. In both cases, the methodology has contributed to reduced well costs and alleviated production losses due to sanding and sand control complexities.
