Thanks Gwen. First, I'd like to thank our global team of employees for providing innovative solutions, integrity, and superior service to our clients. The team's collective dedication to servicing our clients has been very visible during the current challenges, and it's the foundation of Core Lab success. Turning first to reservoir description. For the third quarter, revenue came in at $79 million, up slightly sequentially. Operating Income ex-items was $8.6 million, up 14% sequentially and operating margins ex-items improved to 11%. The segment improvements occurred despite disruptions caused by Gulf Coast storms and the global pandemic. By the nature of the business reservoir description's performance historically has lagged directional changes in client activity. As industry activity recovers, reservoir description will respond more slowly than say oilfield service companies with direct exposure to well construction and other early cycle client spending. As we look ahead, we see the growing international rig count is a harbinger of an improving landscape for reservoir description. A trend that we project will play out throughout 2022 and beyond. Now to some operational highlights. During the third quarter of 2021, Core's Advanced Technology Center in the United Kingdom launched an analytical program to provide both Core and Fluid Analysis on a client - for a client operating in the North Sea. Conventional core was recovered from sandstone strata in the targeted reservoir interval. Once the core reached the rig floor upon recovery from the subsurface, they were stabilized using proprietary Core Lab techniques that ensured that the natural rock fabric and pore fluids were retained during handling and transportation. Upon arrival at the laboratory, the core was scanned using Core's proprietary non-invasive testing and reservoir optimization technologies branded as NITRO, NITRO includes proprietary dual energy, computed tomography and high resolution spectral gamma logging. The results quickly provided Core's clients with lithologic information as well as a wide range of critical petrophysical parameters for pay delineation. NITRO deliverables are normally available within a week of receiving the core. These initial analyses are being utilized in conjunction with Core's recently expanded machine learning artificial intelligence algorithms to refine and accelerate sample selection for the traditional time honored physical measurement program. Single phase subsurface reservoir fluid samples from the same North Sea well were also brought to the Advanced Technology Center for testing. The analyses included detailed determination of contamination levels from the drilling mud, compositional profiling of the hydrocarbons, speciation of sulfur compounds, and measurement of physical properties including density, viscosity, gas oil ratio and bubble point. Quick turnaround on the resulting rock and fluid analytical data sets allowed Core's clients to make timely decisions supporting two upcoming sidetrack appraisal wells. In other international areas, Core's Laboratory in Rio de Janeiro is now offering an expanded range of testing capabilities, including many of Core's proprietary and patented technologies that are in high demand throughout Core's global client base. These proprietary offerings include Core's dual energy CT Rock Evaluation Technologies, and Core's Automated Digital Imaging System which robotically captures high resolution images of core material. The CT datasets and photographic images are being delivered to the clients via Core's proprietary web enabled data management system known as RAPID. These technologies and the RAPID data management system were utilized in the third quarter on Brazilian projects, including a fully integrated study of Brazil's Northeastern offshore basin. This multiclient study incorporates stratigraphy, geochemistry, reservoir geology, and seal rock analysis across several offshore depo centers. With the RAPID data management system, multidisciplinary teams located around the globe are efficiently accessing data and collaborating on analytical results. Moving now to production enhancement or Core Lab strengths in both energetic systems and completion diagnostics, help clients optimize their well completions. Revenue for production enhancement came in at $39.2 million, down 3% sequentially. That was driven by lower international sales compared to the second quarter, plus some supply change or hurdles and the suspension of rig operations tied to weather events in the Gulf of Mexico. Operating income ex-items was $5 million, up 29% sequentially; operating margins was 30% for the third quarter of 2021, up over 320 basis points sequentially. Now for some operational highlights, Oriented Perforating Technology is gaining widespread acceptance among US land operators as the preferred method to optimize frac stimulation. Testing shows that well performance is highly correlated to perforating gun alignment accuracy. Moreover, downhole images have shown suboptimal results from perforating systems that require manual alignment of guns in the gun string. During the third quarter, Core's production enhancement team was engaged by a Permian Basin operator to deploy Core's innovative patent pending Oriented GoGun. This next generation design provides a plug and play system that removes inaccuracies associated with the manual alignment of the guns, as is required with other gun system offerings. In addition, the Oriented GoGun eliminates the need for orientation sub-assemblies, greatly lowering assembly time. The innovative Oriented GoGun design results in the highest degree of alignment accuracy among externally Oriented Gun System offerings, both from gun to gun and from stage to stage. As a result of superior gun alignment and expedited string assembly, the operator adopted the system for all the wells in their multi well drilling pad. Also in the third quarter of 2021, Core's Completion Diagnostic Services were called upon by a Permian Basin client to assess a new approach to cementing operations for their horizontal unconventional wells. It's often difficult to maintain stage containment, when non uniform cement placement has occurred, resulting in channels behind pipe. Frac fluid can move along these channels and migrate between targeted intervals. As a consequence, channels behind pipe can result in sub targeted intervals being under stimulated. The client wanted to evaluate if casing rotation while cementing would eliminate channels behind pipe. Core utilizes its proprietary SPECTRASTIM tracers, and SPECTRASCAN logging technologies to compare the degree of frac fluid containment in a horizontal well, in which casing rotation was employed during the cementing operation. That well was then compared to adjacent wells, in which no casing rotation had been deployed. Core's Completion Diagnostics engineers were able to confirm more uniform cement placement and better containment of frac fluid when pipe rotation was employed. In comparing oil production between the rotated pipe well, and the wells in which no pipe rotation had been performed, the client observed an increase of 800 barrels of oil per 1000 feet of treated well, in just the first 80 days of production from the rotated pipe well. With these favorable results, the operator elected to implement pipe rotation in subsequent cementing operations. Core's Completion Diagnostic Technologies are an invaluable tool for assisting operators in their assessment of innovations and completion techniques. That concludes our operational review. We appreciate your participation, and Debbie will now open the call for questions.
