Hybrid Sand-Consolidation Fluid Offers Versatility in Treatment of Shallow Reservoirs

The Tunu giant gas field is in the Mahakam region of the South China Sea. Because of the maturity of the field, the producing layer has moved from the deep zone of consolidated sand into the shallow zone of unconsolidated sand. Hydrocarbon production from the shallow zone is unmanageable without primary sand control downhole. In this paper, a new type of sand-consolidation low-viscous binding material, based on a combination of inorganic and organic components, is presented.

Introduction

Tunu produces almost 40% of total gas production in the Mahakam region.
