Benchmark Helps Select Best Technique for Sand Control in Field Development

This paper shares the engineering approach used to determine where and when sand control was needed in offshore Malaysia on the basis of geomechanical sand-free critical-drawdown-pressure (CDP) evaluation for the selected well type, configuration, and completion. The decision to implement a proper method of sand control can be made by comparing the CDP with the minimum drawdown pressure (MDP) required to meet the target production rate. Sand-control-method selection was based not only on the sand-particle-size distribution, well life, and mode of well production but also on maximizing oil and gas recovery per well.

Introduction

The challenge in Malaysia was to design and implement a sand-control completion that could maximize well productivity with a stable wellbore under perceivable changing offshore production conditions implemented at the lowest cost.

The objectives of setting up the sand-control benchmark for the Malaysian field were

  • To reduce the sand-control completion costs by greater than 50%
  • To drive a sand-control well-design culture change for developing cost-effective well completions for sandstone reservoirs
  • To determine selectively where, when, and what sand control is needed in the developing reservoirs
  • To enable well-placement and reservoir-penetration-trajectory design to maximize sand-free‑production drawdown pressure
  • To optimize the use of expensive sand-control methods
  • To estimate sand critical erosion pressure drawdown
