Casing Drilling

The evolution of casing while drilling (CwD) illustrates the economic, efficiency and health, safety and environment benefits achievable with the seamless integration of downhole tools and surface drilling equipment. However, several technology gaps have restricted CwD from reaching its full potential to optimise the well construction process. This paper describes the integrated development and application of a retrievable Enhanced Casing Installation (ECI) system, engineered to take directional (Level 3) casing drilling technology to another level and further expand the functionality of both specialised and standard land drilling rigs. The system, which enables directional drilling with composite casing and standard mud motors, differs from typical Level 3 CwD methodologies in that the composite option allows bottom hole assembly (BHA) placement inside the shoetrack, thus helping reduce vibrations and wear on the reamer and other downhole tools. Along with increased well stability and allowing simultaneous logging/measuring while drilling, the ECI device is configured with a comparably lightweight BHA, requiring fewer components, such as jars and roller reamers, making it easily retrievable with cable. As discussed, the cost-effective integration of downhole and surface equipment is clearly reflected in the capacity to rerun the retrieved bit and reamer – a marked difference between the sacrificial bits required for the commonly used Level 2 (vertical) CwD technique. Moreover, the authors will present results of a specialised test stand evaluation and subsequent field trial, where the system was integrated on a fit-for-purpose rig and used for casing drilling at a 45° angle with the BHA pulled intact from 1800 m MD.

Casing Drilling

Abstract Casing drilling technology, as an alternative to conventional drilling, has been known for a long time. This method is mainly used for wells with geological complications, such as lost circulation or wellbore instability of various nature. By using drilling on a string for a section or part of it, the problem interval is immediately cased, eliminating the time spent on additional operations, such as pulling the bottom hole assembly (BHA), wiper trips and running the casing. Thus, this allows to reduce the time for well construction, reduces the risk of accidents and non-productive time associated with the complication zone. Casing drilling has become widely for drilling vertical surface conductors and technical casing with a drillable shoe, as well as for drilling with retrievable BHA in inclined sections for 324- and 245-mm casing. The aim of this work was to perform directional drilling on a 178mm production casing in an interval where the client had geological problems associated with running casing due to a zone of rock collapse. The uniqueness of the task lies in the fact that no one in the world has yet performed drilling on a casing with a building inclination and landing into a horizontal plane. It was necessary to follow the designed well trajectory, to build inclination from 67 to 85 degrees with the planned dogleg severity of 1 degree / 10m.

Traditional pipeline technology will be severely challenged as developments continue in arctic regions. Cost-effective solutions to these challenges can be found through innovative technology and its implementation. TransCanada PipeLines has been involved in a series of technology programs that have been implemented in challenging climates including permafrost. In addition TransCanada is also involved in ongoing programs whose aim is to reduce the cost of Northern pipelines whilst at the same time provide structural assurance and reliability. This paper will describe the overall approach to developing cost-effective solutions and how these programs are interconnected. The topics to be covered will include the approach to strain-based design and how TransCanada has been taking advantage of the approach in its implementation of higher strength steels. The work also includes the approach taken in terms of the design for the effect of mismatch between the pipe and weld metal properties. The strain-based approach is also being extended to a structural reliability methodology and the work conducted to date will be briefly discussed. A significant portion of the design of a Northern pipeline relies on the development of a frost heave-thaw settlement methodology and the current philosophy and its validation will be discussed. A prime consideration of the regulatory bodies is the assurance of structural integrity and fracture control plans. The work currently ongoing at TransCanada on fracture safe behaviour will be discussed. Additional discussion on construction related topics will be covered including welding, buoyancy control, directional drilling and trenching.

River Valleys

The use of directional drilling techniques for pipeline river crossings has increased sharply over the past few years in Canada and the United States. Improvements in drilling technology and increased experience among a growing number of specialty contractors has helped to reduce the cost of directionally drilled installations and to reduce the risks. The advantages associated with reducing disturbance of the water course by the use of directional drilling are often considered to outweigh the additional costs typically associated with the method. While the advantages of using directional drilling methods are compelling, the technique is not universally suited to all river valleys due to considerations of valley topography and geological setting. Specifically, there are certain geological and geometrical conditions that make the method completely unsuitable. In other cases, the geology beneath the river channel and the valley geometry may present a challenge to a drilled installation that can be overcome with adjustments to the design and drilling technique if anticipated. The implications of encountering unfavourable geological conditions during construction can be significant. The implications can range from substantial construction cost overruns up to several times the original bid price, to installations that cannot be safely put into service and must be abandoned. Under certain geological and geometrical conditions, the risk of blowout or fluid leakage to the water course during installation may be significant. The role of geotechnical and subsurface investigations to identify geological conditions prior to commencing construction is more critical for a drilled installation than for conventional trench techniques, as the consequences of encountering unanticipated conditions can be much more severe with drilled crossings. In addition, a trenched crossing is inherently more flexible than a directional crossing in terms of the ability of the contractor to adapt to different conditions than those anticipated at the start of the work.

Cost Awareness

Introduction: In the current economic climate with continuous expenditure reviews and financial constraints, clinicians should remain conscious of making cost-effective choices on consumables and medications. In this survey, we evaluated the cost awareness amongst UK urologists. This is an observational study in which urology clinicians were asked to estimate the cost of 10 commonly used medications and consumables in urology by completing a questionnaire. Methodology: The survey was primarily conducted at the BAUS Annual Meeting 2017 with subsequent responders at local hospitals and urological courses. The costs of consumables and medications were verified with the relevant companies and the 73rd edition of the British National Formulary. Result: There were 139 responders from across the UK (46 consultants, 64 training registrars, 13 trust grades doctors and 16 senior house officers (SHOs)). In total, 16 and 60% of all estimates were within ± 25% and ± 100% of the true cost of the items respectively. Approximately 97.1, 95.7 and 97.1% overestimated the cost of a 14Ch urethral catheter, Ciprofloxacin and Sildenafil, respectively; while 78.4 and 84.9% of responders underestimated the cost of a JJ ureteric stent and Solifenacin, respectively. On multivariate analysis, SHOs significantly overestimated the cost of urethral catheters, suprapubic catheterization kits and JJ ureteric stents compared to other clinician grades. Conclusion: Cost awareness among UK urologists is poor. Expensive items (e.g. JJ ureteric stent, Solifenacin) tend to be underestimated while inexpensive items (e.g. catheter, Ciprofloxacin, Sildenafil) tend to be overestimated. This lack of appreciation of value may have an impact on drug and consumable expenditure. Level of Evidence: Level 3

The conceptual design of floating ship shape platform for well maintenance, survey and workover in prospective fields of Russian Arctic and Sakhalin Island shelf (further The platform) was developed by Krylov State Research Centre specialists with the assistance of CDB “Korall”. The platform under design intended for operation in the Arctic conditions and designed to resist the ice formations such as continuous thin first-year ice and broken ice being the first one in the world practice. The form and chosen hull ice strengthening class allow ensuring safe operation in the mentioned ice conditions. The main purpose for development of the platform was to minimize the offshore wells downtime providing the cost effective way for maintenance of subsea production systems comparing with floating drilling rigs and drilling vessels that takes a significant investment. The economic assessments have shown that operation of such platform will cost two to three times less than renting of a rig or drillship. Having the working deck space of about 1,000 m2 and the ability to download a variety of equipment the platform can perform a variety of testing and wells repairing procedures both for underwater wellhead and for wells operated on fixed platforms.

The Internet has emerged in the last few years, not just as another communication means, but as sheer power and access to it provides access to a lot of information. Lack of access to internet will bring strong digital divide between rich and poor countries and also brings strong divide within the rural and urban communities of a country which in turn will affect the socio- economic development of a country. So there is a need for low-cost information technologies that are suitable to the conditions prevailing in a developing or third world country. Broadband CorDECT is one of the cost-effective fixed wireless broadband Access Solutions used for networking and building knowledge societies in a developing country. It is based on the DECT standard specification from the ETSI. It provides a complete wireless access solution for new and expanding telecommunication networks with seamless integration of both voice and internet services. It has been designed and specified to inter-work with many other types of network, such as the PSTN, ISDN, GSM and more. Broadband CorDECT provides the basic telecommunications as well as broadband Internet services and thus bridges the digital divide and such a service cannot be provided by any other product today in the world even double the cost. This paper discusses the relevance of broadband CorDECT in the context of current trends and provides a description of the technology.

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

Summary Objective: The goal of the study was to assess the effectiveness and patient tolerability of single-session, sonographically guided, transcatheter foam sclerotherapy and to evaluate its economic impact. Patients, methods: We treated 20 patients with a total of 22 varicoses of the great saphenous vein (GSV) in Hach stage III-IV, clinical stage C2-C5 and a mean GSV diameter of 9 mm (range: 7 to 13 mm). We used 10 ml 3% Aethoxysklerol®. Additional varicoses of the auxiliary veins of the GSV were sclerosed immediately afterwards. Results: The occlusion rate in the treated GSVs was 100% one week after therapy as demonstrated with duplex sonography. The cost of the procedure was 207.91 E including follow-up visit, with an average loss of working time of 0.6 days. After one year one patient showed clinical signs of recurrent varicosis in the GSV; duplex sonography showed reflux in the region of the saphenofemoral junction in a total of seven patients (32% of the treated GSVs). Conclusion: Transcatheter foam sclerotherapy of the GSV is a cost-effective, safe method of treating varicoses of GSV and broadens the spectrum of therapeutic options. Relapses can be re-treated inexpensively with sclerotherapy.

This research proposed a model to assist the design of the associated data architecture and data analytic to support talent forecast in the current accelerating changes in economy, industry and business change due to the accelerating pace of technological change. The emerging and re-emerging economy model were available, such as Industrial revolution 4.0, platform economy, sharing economy and token economy. Those were driven by new business model and technology innovation. An increase capability of technology to automate more jobs will cause a shift in talent pool and workforce. New business model emerge as the availabilityand the cost effective emerging technology, and as a result of emerging or re-emerging economic models. Both, new business model and technology innovation, create new jobs and works that have not been existed decades ago. The future workers will be faced by jobs that may not exist today. A dynamics model of inter-correlation of economy, industry, business model and talent forecast were proposed. A collection of literature review were conducted to initially validate the model.

The choice of cost-effective method of anticorrosive protection of steel structures is an urgent and time consuming task, considering the significant number of protection ways, differing from each other in the complex of technological, physical, chemical and economic characteristics. To reduce the complexity of solving this problem, the author proposes a computational tool that can be considered as a subsystem of computer-aided design and used at the stage of variant and detailed design of steel structures. As a criterion of the effectiveness of the anti-corrosion protection method, the cost of the protective coating during the service life is accepted. The analysis of existing methods of steel protection against corrosion is performed, the possibility of their use for the protection of the most common steel structures is established, as well as the estimated period of effective operation of the coating. The developed computational tool makes it possible to choose the best method of protection of steel structures against corrosion, taking into account the operating conditions of the protected structure and the possibility of using a protective coating.
