... Abstract As an oilfield matures, the economics of continuing production are heavily influenced by the day-to-day lease operating expenses (LOEs). One major component of LOEs can be the artificial lift. The objectives of this case study were to evaluate the economic improvement of a brownfield...

... the unique challenges of geothermal drilling, ensuring safe and efficient operations by providing stability, lubrication, and hydraulic control within the wellbore. This review explores the role of optimized drilling fluids in geothermal drilling, covering the benefits of geothermal energy, the specific...

... Abstract In drilling operations, deploying a real-time monitoring and detection model to identify early kick and loss events is essential for ensuring safety and achieving operational success. The model presented has the capability to accurately recognize various phases of the drilling process...

... corrective action is not taken, the accumulation of rock material spalling into the hole from breakouts of significant size can also impair drilling and completions operations, and in extreme cases, the hole can be lost due to packoff leading to stuck pipe (Zoback et al. 2003; Blanton and Teufel 1985...

... Friction reducer (FR) is a chemical additive utilized in hydraulic fracturing operations to minimize friction between the fracturing fluid and the wellbore walls. Its purpose is to overcome tubular drag during high-flow-rate pumping in stimulation treatments. In recent years, there has been a growing...

... The proposed methodology aims to accurately estimate fracture half-length during hydraulic fracturing operations by integrating real-time FDIs and post-stage fall-off analysis. This integrated approach allows for a comprehensive understanding of well interference and enables the identification...

... degradation. The reaction between calcium carbonate and iron sulfide with HCl can produce an elevated amount of CO 2 and H 2 S, respectively which are not present in normal operations. Additional safety measures taken in these operationally induced sour conditions are detailed in this paper. Through...

..., including plunger fall, gas injection, pressure buildup, and production. First, the GAPL well production history was analyzed to evaluate the well operating condition. Then, a transient simulator was used to model the well flow behavior and production performance with GAPL. The study demonstrated the GAPL...

... Abstract In the past ten years, hydraulic fracturing technology and strategies have made major improvements in the operational efficiency and economic performance of shale well completions. Much of this advancement was derived in the past three years as a response to the global downturn in oil...

... to minimize nonproductive time (NPT). Frac plugs plays vital role in hydraulic fracturing in isolating the multiple zones of the wellbore for operations up to 10,000 psi pressure and 250°F temperature. In this paper advanced computational analysis is conducted to optimize the composite frac plug design...

... such as the laws of thermodynamics and conservation of momentum. The coupling of constitutive equations with first principle physics is adequate for a specific array of operational conditions. However, they give unsatisfactory results when developed in dissimilar conditions ( Saputelli et al. 2003...

... Abstract "Gas migration" has been the catch phrase of the Appalachian Basin in the northeastern part of the US for years. As demonstrated in a previous study, optimal displacement efficiency can be obtained by rotating casing during the entirety of the cement operation, providing uniform cement...

... and quaternary amine combination These wells flow into centralized compressor stations. Treatments were prioritized during the annual station maintenance shutdowns to both minimize lost production and increase residence time of biocide. The operations group decided to do the follow-up testing and all future...

... Abstract Management of produced water from conventional plays and shale and tight oil and gas plays is driving subtle yet potentially consequential changes in certain regions and Underground Injection Control (UIC) formations. UIC operation topics of interest include induced seismicity (from...

... Abstract Characterization of the lateral heterogeneity of reservoir properties is an important consideration during the design of horizontal completion operations in unconventional plays. Traditional geometric designs do not differentiate adjoining rocks based on lateral heterogeneity...
