Abstract A new family of water-based drilling fluids that contain nano-particles has been tested to evaluate its interaction with shales. It was shown in an earlier paper dramatically reduce the flow water into a shale formation. In this study we have developed and commercially available can be used drill Drilling formations offers some tremendous environmental economic advantages. To date use such limited hard shales as Barnett. lab applied much broader range Water-based formulated...
Abstract Experimental tests have been performed to investigate the applicability, effectiveness and engineering of various wellbore strengthening techniques which increase mud weight window by adding lost circulation materials (LCM) drilling fluids. The experimental include fracture sealing known apertures simulated two plates, induced or natural fractures in a sandstone shale block with borehole, transparent cylindrical LCM particles transport cell, allows visualization how seal is formed...
Abstract Interface engineering is an efficient strategy to create high‐performance electrocatalysts for water splitting. In the present work, CeO 2 @CoSe nanoneedle on carbon cloth (CeO /CC) demonstrates high efficiency oxygen evolution reaction (OER) and with abundant O vacancies facilitates adsorption of OH − boosts reconstruction CoSe into CoOOH at lower potentials. The in situ generated active @CoOOH heterointerface upshifts d‐band center Co site, thereby decreasing free energy...
In this study, the output energy in topological insulators (TIs)-based Erbium-doped fiber laser (EDFL) was improved using two strategies: bidirectional pumped cavity and saturable absorber (SA) with high damage threshold large modulation depth. Using chemical vapor deposition (CVD) method, Bismuth Selenide (Bi2Se3) film synthesized to a SA. Employing CVD-Bi2Se3 SA an EDFL, bright bright-dark soliton operations were achieved. The average power/pulse 82.6 mW/48.3 nJ 81.2 mW/47.5 nJ,...
Isothermal and thermomechanical fatigue of 63Sn/37Pb solder is studied under total strain-controlled tests. A standard definition failure proposed to allow inter-laboratory comparison. Based on the suggested criterion, load drop per cycle, Young’s modulus ratio maximum tensile compressive stresses remain constant, response stable before failure, although cyclic softening was observed from beginning. Experimental results isothermal tests for a strain range 0.3 3 percent show that log-log plot...
We demonstrate the generation of versatile mode-locked operations in an Er-doped fiber laser with indium tin oxide (ITO) saturable absorber (SA). As epsilon-near-zero material, ITO has been only used to fashion a as nanoparticle-polyvinyl alcohol SA. However, this type SA cannot work at high power or ensure that materials can be transmitted by light. Thus, we covered end face uniform film using radio frequency magnetron sputtering technology fabricate novel Using new SA, single-wavelength...
In this study, a double-end pumped high-power passively mode-locked erbium-doped fiber laser (EDFL) was realized by employing few-layered In2Se3 flakes as saturable absorber (SA). Herein, the uniform large-scale were synthesized physical vapor deposition (PVD) method. The PVD-In2Se3 SA exhibited remarkable damage threshold of higher than 24 mJ/cm2. Meanwhile, had modulation depth and intensity 18.75% 6.8 MW/cm2, respectively. Based on SA, stable bright pulses emitting at 1559.4 nm with an...
Abstract As an industry, we are still in the early stages of learning curve for shale gas drilling although many wells have been drilled recent years. Data from over one thousand Maverick basin since 2003 were retrieved internal database. Among them two hundred horizontal Eagle Ford play by 31 different operators between 2008 and 2011. The analyses performance data these offer establishment general practice guidelines recognition opportunities improvement drilling. Oil-based fluid, or "mud"...
Abstract Although key shale gas plays vary considerably in terms of reservoir pressure, temperature, mineralogy, and in-situ stresses, the principal drilling-related issues are wellbore stability, inhibition, hole cleaning rate penetration. Because many reservoirs either environmentally sensitive or densely populated areas, stricter environmental regulations will require new types environment-friendly water-based drilling fluids. The traditional inhibition method through chemical use invert...
The wide applications of terahertz (THz) wave technology in the ∼1-3 THz range has resulted a surge demand for performance improvement detection technique.

Moreover, to effectively increase signal-to-noise ratio low range, beam isolation enhancer proposed and its effect verified. minimum detectable...
Abstract Natural gas production from organic shale is one of the most rapidly expanding trends in North America's onshore oil and exploration today. In some areas, this has included bringing drilling to regions that have seen little or no activity past. Advances horizontal technology hydraulic fracturing made gas/oil economically viable. Haynesville Marcellus plays are among active United States. The potential for these plays, coupled with other unconventional predicted contribute...

Abstract Drilling waste disposal using hydraulic fracturing is often the preferred management option because it can achieve true zero discharge without being limited by drilling location. This particularly for operations in remote and challenging areas such as offshore Sakhalin Island there no established infrastructure management. paper presents a case history of managing uncertainties risks related to drill cuttings re-injection (CRI) project Island. Although are with CRI this case,...
Summary In April 1998, a program for continuous deep disposal of drill cuttings and open pit materials was initiated on the North Slope Alaska. This ongoing injection project is commonly referred to as GNI, or "Grind Inject." Accumulated drilling mud slurry are injected into receptive Cretaceous soft sandstone in three wells: GNI-1, GNI-2, GNI-3. Typical operations involve injecting one wells continuously number days then switching another well. The average rate approximately 30,000 B/D. As...
