"The industry is caught between the engineering challenges of increasingly complex completions and the need to reduce overall completion costs to improve well economics," said David King, senior vice president, Halliburton's Completion and Production Division. "Halliburton has analyzed the challenges posed by water or gas breakthrough in order to simplify sand control completions while increasing reliability."
Wells are often drilled in formations prone to unwanted water or gas production, which displaces the flow of hydrocarbons. In conventionally completed wells, water or gas breakthrough is addressed through remedial treatments. Halliburton's proprietary EquiFlow Oil Selector valve helps to prevent unwanted water or gas from entering the production string. This enables operators to avoid down time and reduces operational costs associated with remediation and the handling and disposing of produced water.
Horizontal completions increase contact with the reservoir to help optimise production, but there is the risk of water or gas breakthrough, which may ultimately result in having to abandon the well. The unique design of Halliburton's EquiFlow inflow control device (ICD) helps operators capitalize on optimum reservoir contact with horizontal wells by delaying water or gas breakthrough to increase productivity and ultimate reservoir recovery.
The PetroGuard Advanced Mesh screen technology resists plugging in heavy oil and also in variable quality pay sands that would otherwise require the expense of more complex gravel pack installation. Unlike conventional oilfield screens that can plug rapidly, the unique construction of PetroGuard Advanced Mesh screen increases the application range of screen-only completions, thereby reducing overall completion costs.
