Excessive sand and fines production could reduce well productivity, induce well mechanical integrity degradation, affect flow assurance and HSE. An integrated sand management plan which entails designing and implementation of a proper subsurface sand control completion and surface sand production monitoring and handling, shall be developed as a key part of field development and well and reservoir management plans.
This session will discuss experiences in managing sand issues from an operator’s perspective.
This session will focus on key factors influencing sand production and the associated risks from the geo- or rock- mechanics perspective. The sanding behaviour, including timing of sand production, is dependent on a number of factors such as formation strength, in-situ stress distribution, drawdown pressure as well as impact
of flowing fluids – which is particularly relevant to depleted wells with high water cut. The session topics may include rock mechanics and physics, sand onset prediction, formation failure modes, sand amount estimation and various predictive modelling approaches to assist in the overall sand management strategy.
This session will focus on key factors in selecting the optimum sand control option: avoiding the sanding conditions, excluding downhole or co-producing the sand to surface. Once the critical conditions and risks are identified, sand management decision will be based on the severity & timing of sanding, the overall well productivity & reservoir
management, facility requirements and erosion risks. Session topics include challenges in sand volume estimation, transport modelling and monitoring, surface handling issues, near real-time decisions and case studies.
This session will focus on sand management and sand control in depleted reservoirs. Depletion results in an alteration of the reservoir stresses that can trigger sand production, lower frac gradients and cause compaction. Session topics and case histories include sand management in wells completed without sand control, passive sand control solutions, managing fluid leak off and completion integrity.
This session will focus on solid control on challenging formation. Session topics and case histories include the review of current approaches for sand control on extreme laminated sands as well as the handling of water sensitive zones. The session expands to solids control on unconventional resources as seen in Coal Seam Gas and the challenges associated with it.
This session will focus on repairing sand producing well using chemical consolidation. Three applications of consolidation technology will be discussed. The first will presents epoxy consolidation for remedial sand control in a low value asset. The second topic centers around the repair of failed open hole screen installation.
The session finishes with a presentation of an alternative consolidation method aimed at inhibiting fines migration while increasing the maximum sand free rate. This session will interest anyone working in brown fields where unforeseen sand production occurs.
This session will examine the optimum sand management/control completions for long term injectivity of water injection wells. Related topics will include:
Case histories of sand control installation and long term performance will be given.
Intelligent completions with sand control are some of the most complex completions the industry performs. They have been carried out in both cased and open holes. This session will look at the current state of the art technologies for intelligent wells with sand control through a combination of case histories and theoretical discussions. This session should be of interest to anyone interested in combining flow control (both passive and active) with sand control in either cased or open hole.
Despite advances made in the matter of hot spot prediction, screen size selection and sand control design criteria, sand control failures are still reported. Preventive (flux limitation) and reactive (choking) methods can reduce sand production but also affect well productivity.
To tackle this, various remedial sand control solutions have been developed; examples include through tubing screens, through tubing gravel packs and chemical injection. This session will examine the different options and their applicability depending on initial lower completion, reservoir properties and operational capacities.
As sand management and control applications extend into increasingly challenging environments, the industry has to look more closely at historical practices while working on new technology and methodology to address future needs. This session focuses on developments in understanding the methodology and technology that are challenging conventional practices, helping to expand the sand control application envelope; these developments address the future for long term, cost-effective sand control solutions.
