Case Study: Illusion® Frac Plug Helps Eliminate High-Risk Millout Operations

Operator removes risk of intervening in a depleted wellbore when milling out composite plugs CHALLENGE – For upcoming high-density well-spacing trials, the operator primarily wanted to remove the risk of intervening in the depleted wellbore when milling out composite frac plugs. Those risks, unmitigated, can put higher-density drilling programs at risk due to the steep costs and time delays created when millout challenges are encountered. SOLUTION...

Tech Paper: Offshore Coiled Tubing Interventions Maximized the Value of Watered Out Mature Fields…

Coiled tubing helps sustain production in deep sandstone formations Saqqara is a very challenging field in the Gulf of Suez in the Red Sea area, producing from the deep sandstone Jurassic formation. This formation can sometimes be watered out, with a combination of high H2S and CO2 levels in the production. High sand quality has developed high horizontal and vertical permeability, which challenges any water shutoff...

We Can Help Maximize the Value of Your Mature Fields in this Market Downturn

The Halliburton collaborative framework for mature fields’ diagnoses challenges, designs solutions to improve production and increase recovery, and delivers these solutions to enable you to maximize the value of your assets. In a recent project, we found potential for a client to increase their total production by over 250%, with a rate of return of over 200%, within a matter of months. These benefits were forecasted...

Tech Paper: Advanced Geosteering Technology Promotes the Accuracy of Well Placement in the Thin Reservoirs of China Mature Oilfield

Safely and efficiently maximize reservoir exposure in mature fields After more than a decade of producing oil from the thick marine sand reservoirs in the HaDeXun oil field in the Tarim basin of western China, focus has shifted to the challenges of drilling thinly laminated reservoirs. To maximize efficiency and production, geosteering services, as well as bottomhole assembly (BHA) and bit optimization, were used for the...

Tech Paper: Developments in Sandstone HF Acidizing: HF Fluid Compatible with Na or K Brines and Carbonate-Laden Mineralogy for High Temperatures (360°F)

Aminopolycarboxylic acid chelating agent helps with the removal of mineral buildup in sandstone formations Using hydrofluoric (HF) acid for the removal of clays and silica minerals impairing permeability in sandstone formations requires fluids free of sodium or potassium ions. High temperatures (> 300°F) further limit HF acid use and its effectiveness because of potentially damaging effects to the formation and its corrosivity. This paper discusses laboratory testing of...

Well-considered perforation strategies can enhance mature field production

Using an optimized hydraulic fracturing perforation strategy to maximize production may increase cash flow by accessing missed pay. (Hull, 2015) Well-designed perforations are vital to a well’s completion because they are the connection between the wellbore and the formation. To avoid cuts to incremental production, operators should consider the challenges involved in correctly perforating. For example, maintaining high static differential pressure (underbalance) is required to prevent...

Tech Paper: Alternative Technologies in Drill-In Fluids for Depleted Reservoirs

Designing the right drill-in fluid system can help minimize productivity impairments Induced losses occur when the drilling fluid density, required for well control and to maintain wellbore stability, exceeds the fracture resistance of the formations. Depleted reservoirs present a particular challenge. As the reserves decline, the pore pressure decreases, which weakens hydrocarbon-bearing rocks. Nearby or interbedded low permeability rocks, however, may maintain their pore pressure. This scenario...

Mature Field Rejuvenation with Infill Drilling

In this tough economic climate, efficient mature field rejuvenation has become a major challenge for operators looking to balance the books. The most successful mature field rejuvenation projects are ultimately driven by a solid understanding of the existing infrastructure, reservoir geometry, and remaining hydrocarbons in place. Most large mature fields were initially developed long before many of the technologies we use today were available, such as permanent reservoir...

Riding the Tide During Troubled Times With Mature Fields Management

Mature fields management through integrated asset teams and purpose-driven technology deployment Energy in its various forms is the perennial building block that keeps this world ticking. The oil and gas industry is one of the most significant contributors to the ever evolving growth we see in everyday life. The impact of the current oil price on the global economy has been profound, with crude prices currently trading at...
