Dual zone gravel pack completions, mostly the preferred sand control mechanism of choice in unconsolidated stacked reservoirs, can be quite expensive in marginal field environment, particularly in the Niger Delta region due to high logistics and security costs associated with rig costs. This cost escalation (Rig spread, logistics, security and associated costs) progresses from land to swamp and ultimately offshore locations. Conventional techniques for such completions involve multiple trips in and out of the hole with gravel pack and isolation tools, with pumping stages and a wireline trip to set the sump packer. This process typically takes between 12-14 days and has often resulted in border line economics, when this technique is applied in a marginal field.In this paper, we present a different sand control technique for carrying out a cost-effective completion for a two zone well in a marginal field, situated in the Niger Delta. This technique involves the use of Multi Mesh Screen (MMS) and can eliminate the use of gravel pack pumping treatments for several applications. It has specific design criteria for enhancing sand control and has found great application as standalone screen in cased hole.The proposed system involves the combination of a special MMS with engineered electric-line deployed perforating technique. The entire deployment of a two zone completion required only about four days of rig time. Post completion, the deeper interval has been producing at an average oil rate of 220 bopd and associated gas production of 0.35 MMscf/d while the shallow interval has average production of ca. 500 bopd with associated gas production of 0.35 MMscf/d. Both intervals have performed at an order of magnitude higher than the predicted sand-free production rate without any or other conventional sand control methods. Overall, the use of this adaptive completion technique resulted in some 50% cost savings to the operator compared to the conventional gravel packing of both zones. This has greatly enhanced the economics of the well. The details of the installation design, field procedures along with an analysis of the production data and an economic comparison to the alternatives are presented herein.
