Gas Migration Control and Risk Evaluation
DrillPlan by Schlumberger offers a comprehensive suite of gas migration control solutions, providing reliable and cost-effective well cementing options. The company's gas migration control suite enables thorough risk evaluation, allowing for the selection of tailored action plans customized to specific applications. The CEMENTICS Gas Migration Analysis module software plays a critical role in this process, evaluating the severity of gas migration risks based on the pressure decay limit. This limit measures how far the cement slurry setting process can progress before hydrostatic pressure drops below reservoir pressure, potentially allowing gas to migrate into the annulus. Integrated with CEMENTICS zonal isolation software, the Gas Migration Analysis module provides detailed evaluations, automatically identifying the zone with the highest risk level when multiple gas zones are under assessment. Following risk identification, Schlumberger's engineers advise on risk reduction strategies, including placement process design, pumping schedules, and the formulation of suitable slurry and additives.
Gas Migration Control Additives Portfolio
Schlumberger's gas migration control additives portfolio includes specialized products such as D620 GASBLOK, D500 LT GASBLOK, D168, and D193. These additives are designed to address gas migration and fluid loss issues, offering effective solutions for unique cementing requirements. The D620 GASBLOK and D500 LT GASBLOK additives specifically target gas migration control, providing enhanced performance and reliability in cementing operations. Additionally, the D168 and D193 additives offer solutions for fluid loss and gas migration control, contributing to optimized well cementing outcomes. Each product in the portfolio is tailored to meet the diverse needs of well construction projects, ensuring efficient gas control and cementing success.
Related Resources and Case Studies
In addition to its gas migration control solutions, Schlumberger provides a range of related resources and case studies that highlight the effectiveness of its products. For instance, the UNIFLAC Universal Fluid-Loss Additive product sheet offers insights into fluid-loss management strategies, complementing the gas migration control solutions. Furthermore, case studies like Lukoil's cost savings of USD 6.8 million through the use of extended-reach intelligent TAML 5 multilateral wells showcase the practical benefits of Schlumberger's innovative approaches. The elimination of sustained casing pressure by Dragon Oil and the efficiency of products like the D256 Liquid FLAC Cement Fluid-Loss Additive further emphasize the company's commitment to delivering high-quality solutions for well construction challenges. By accessing these resources and case studies, industry professionals can gain valuable knowledge and insights to enhance their cementing operations.
