AbstractDevelopment of advanced composite spoolable tubing offers several new solutions to many challenging well servicing and well construction operations. Attributes such as excellent corrosion resistance, low material density and weight, coupled with high working pressure and extensive htigue resistance, make this product attractive for a number of oilfield tubular applications. These include well servicing strings and corrosion resistant completion strings. 'Ihe advantage of an advanced composite spoolable pipe over steel pipe is that it can be "engineered for particular applications to take advantage of the composite's enabling attributes while optimizing the cost. Development efforts led by a spoolable composite products company and an oilfield service company have produced a novel composite spoolable tubing design targeted to meet these well servicing and construction challenges. This paper will review the development efforts and operation issues the developers have addressed to qualifL the advanced composite spoolable tubing for several enabling applications and explore how it will provide operators future solutions. This paper is an update on the development achievements made toward commercialization on the advanced composite spoolable tubulars (emerging technology) presented in the 1997 OTC Paper 8456: "Development and Application of a Novel Coiled Tubing String for Concentric Workover Services. "

Composite Spoolable Pipe for use in the Oil and Gas Industry is a new emerging technology. Enabling benefits include increased corrosion resistance, major weight reduction over steel as well as increased fatigue resistance. One company is close to commercial introduction of composite spoolable pipe for both well servicing and well completion operations. This paper will detail the latest application developments achieved at the time of the conference. It will cover the advancements made since the last update, SPE paper No. 38414 "Update on Composite Spoolable Pipe Developments" presented at the 2nd North America Coiled Tubing roundtable in April 1997. The focus will be on the application of this technology in its first commercial operations. P. 215

Traditionally within the energy industry, much emphasis has been placed upon the gathering and management of geoscientific data for easy access, analysis, and decision-making purposes. Typically, however, much less emphasis has been placed on the management of operational data and its integration with geoscientific, economic, and public-domain data sets. As a result, much of the data is never captured or stored, and attempting to access these data is time-consuming and sometimes unsuccessful. In 1995, Halliburton Energy Services launched a major project to design and implement an environment for managing operational and technical data with integrated applications to access, retrieve, and analyze the data. The foundation of this project was Halliburton's technical data model (HTDM), which has been under development since 1991. While the initial goal was to provide operational and technical data to Halliburton's internal users, it quickly became apparent that efficient management of wellsite data from the point of acquisition presents a major opportunity to the industry for more effective and efficient operations. Informed, timely, optimized decision making is enabled by easy access to these data and by the analysis of these data with integrated application software. Halliburton's plan includes development of a globally distributed relational database with application and communications methods that allow acquisition, access, and analysis of data from any location. This paper also presents examples of successful implementation of the system to lower costs and improve efficiency by effective data mangement. Introduction For years, the energy industry has gathered and managed geoscientific data for easy access, detailed analysis, and critical decision-making. Such data have included those derived from seismic, geologic, petrophysical, and well-test surveys. Typically, however, the industry has placed much less emphasis on managing operational data and integrating that data with geoscientific, economic, and public-domain data sets. Although much operational data has been captured, they are usually found over disconnected and frequently incompatible computer databases. Just as often, operational data are found in hardcopy files in widely separated locations. Thus, the difficulty in gathering operational data from these disjointed sources have made attempts at comprehensive analysis of such data expensive, time consuming and often impractical. Today, operators and service companies concentrate on overall reservoir management and seek the most cost-effective methods to achieve and maintain optimal reservoir performance. A high-quality, well-populated, easily accessible operational database can be analyzed to help minimize operational costs and determine the most successful operational procedures. In 1995, Halliburton Energy Services launched a major project to design and implement an environment for managing operational and technical data with integrated applications to access and analyze the data. This project was named TIMS (Technical Information Management Systems). To implement the operational aspects of the TIMS project, project goals were clarified and workflow processes were reviewed. Then, a comprehensive relational data model and an associated workflow scheme were developed, and software and hardware were selected to implement the database and workflow scheme. The database and workflow are currently being phased into field operations. Project Goals The database and workflow scheme that were to be developed through the TIMS project would:–support and improve mainstay workflow processes across all the company's product-service lines (PSLs)–capture and manage job experience to support decision functions

Depending on the application, composite coiled tubing (CCT) may serve as a cost-effective alternative to conventional coiled tubing.1 Gas wells in Alberta, Canada often lose production when hydrates form as a result of temperature drops in gas flow. To reduce gas-flow temperature drop and prevent hydrates from forming, operators commonly use a steel heater string to heat the annular area between the production tubing and casing. Some wells require more heat to reach the critical hydrate temperature depth than others, resulting in higher costs for heating and pumping equipment. To reduce these costs, operators looked for a solution to temperature drop, and found it in CCT. Because of its low thermal conductivity (heat loss), a CCT heater string can reduce the need for upgrading or replacing surface heating and pumping equipment. Introduction In one study, continuous hydrate problems occurred in a newly completed gas well in Alberta when the well was producing at its potential (Fig. 1, Page 4). Operators inserted a 1 ¼-in. outer diameter (OD) steel CT string into the annulus of the well to a depth of 4,593 ft. They then pumped water heated to 167°F down the string to heat the flow of gas above 80°F, the temperature at which hydrates form. The steel CT failed to retain enough heat to prevent hydrate problems. The only way operators could produce the well was to increase the pump rate and reduce gas flow. An alternative to this costly approach would have been to upgrade the heating equipment, but that, too, would have been expensive. A simulation suggested that replacing the steel heater string with a fiberglass or CCT material with low heat loss values (thermal conductivity 1.92 Btu/hour/ft2-in./°F) could be a solution. This method would not require any changes to the surface equipment. Validation To validate the simulation and prove that a heater string with composite properties would be the solution, operators ran a temperature log while the steel tubing string was being used and the well was flowing. When the temperature log was compared with the simulated results [allowing for the thermal conductivity of steel (77.8 BTU/hour/ft2-in./°F)], the results were comparable (Fig. 2, Page 4). Heater-string inlet parameters were as follows:flow rate 16.0 gal/minpressure 600 psitemperature 167°F With this information, well operators investigated the design of a heater string with composite properties. Design Considerations The OD of any heater string would have to fit easily into the area between the 2 7 /8 -in. tubing and 7-in. casing (ID 5.9 in.). This annular space was effectively 1½ in. (Fig. 3, Page 4). The minimum ID of the heater string would have to be 1 in. to maintain the required pump rate of 16 gal/min. Fiberglass jointed tubing was considered for use, but for fiberglass tubing to maintain a 1-in. ID, the OD of the tool joints has to be larger than 1½ in. Fiberglass jointed tubing would not fit into the annular area. Seeking another solution, operators decided to test CCT. CCT Design Because composite coiled tubing can be manufactured to any specification, a final OD of 1.37 in. was chosen, with the ID remaining at 1 in. This OD would allow operators to easily install the string (Table 1, Page 3).

During the past 12 years, spoolable pipe has become a widespread preference for in-field gathering and injection applications compared to welded steel and stick fibreglass pipelines. It is now broadly used in oil and gas fields throughout North America, with more than 300 end users, including every major operator. To date, more than 25,000 km of spoolable pipe has been installed in North America for more than 450 operators. Fast installation, lower costs, safer installation, immunity to corrosion and low maintenance in service are the drivers for this rapid success. The technology is well on its way to displacing steel or stick glass-fibre reinforced epoxy (GRE) pipe as the technology of choice for lines up to nominal 6-inch in diameter. Compared to a single 8- or 10-inch line, companies are finding having multiple spoolable pipes in the same ditch to be more economical. Field results have demonstrated spoolable pipe’s immunity to corrosion and have also shown how using spoolable pipes can save 25% or more in costs when compared to overall installed costs for welded steel or stick fibreglass pipelines by significantly reducing onsite construction expense, installation time and onsite manpower requirements, including skilled welding personnel.
