Workshop Overview

Sand production from (relatively) unconsolidated reservoirs is a frequently encountered, costly operational problem which has a significant impact on the case of well operation and the economics of oil or gas production. It is usually associated with shallow, young formations, but has also been encountered at depths greater than 4000m. Other types of unstable formations also show similar production problems -i.e. they allow “pieces” of the formation to break away and enter the perforation or wellbore. Soft chalks, shales, siltstones and rubble zones can all flow particles, undergo plastic failure or slough particles due to mechanical formation failure the stresses imposed by well production.

Program Focus

The rock mechanical process that lead to sand production
What institutes a sand production problem from a production operator’s point of view
Indicate the operational measures taken to identify a sand problem well
The various types of sand control. These include sand consolidation and the mechanical methods: screens/prepacks/gravel packing/frac packing
The completion operations required for the installation of sand control
Introduce the new approach to stand alone screen (through tubing and through casing)

Benefits of Attending


The impact of an incorrect decision of whether to allow for the installation of sand control during the original completion design
The reasons for the lack of definition of “what constitutes a sand problem In the field”
State measures taken to modify completion/surface facilities to “live with” sand production
A methodology for predicting sand failure
The various rock mechanical measurement that may help with this prediction
Identify and contrast the advantages/disadvantages of the various sand control options (none, sand consolidation, bare screen, internal and external gravel packs, “Frac and Pack”)
Open hole completions design and drill-in fluid selection
Characteristics and functions of the fluid and proppant used in a gravel pack
How to design a gravel pack be selecting the optimum gravel pack size and fluid for a gravel pack operation

Who Should Attend?


  • Production supervisors
  • Production engineers
  • Completion supervisors and engineers
  • Reservoir engineers
  • Geologists
  • Drilling supervisors and engineers
  • Workover and well service supervisors
