Technology Applications

Field-Mapping Software

Juniper Systems has announced a new release of its field-mapping software, Juniper Aspect 1.2 (Fig. 1). Juniper Aspect 1.2 is aimed at boosting efficiency and productivity while remaining simple, providing global-positioning–system and geographic-information-system (GIS) capability to personnel in the field to streamline processes. Juniper Aspect has the ability to locate, document, and inspect assets and is built on the Esri framework to provide accurate as-built and field-asset documentation verified by GIS technology. The collected information from the handheld device synchronizes with the desktop version of the software, which generates custom reports on the basis of individual mapping needs. Users can edit, manage, and present the maps in whatever way desired, creating a printable file that contains maps, photos, part lists, coverage areas, and notes. Improvements for Version 1.2 include a new feature to filter and organize data more extensively and import large amounts of data more easily into Excel. Operating on most devices running Windows Mobile 6.0 or higher, the software is designed with an intuitive user interface for ease of use and a short learning curve.

Silica Analyzer

Hach Company has introduced its 5500sc silica analyzer. The 5500sc has a unique pressurized reagent-delivery system with an onboard air compressor that helps eliminate frequent maintenance associated with the use of traditional pump systems (Fig. 2). The 5500sc can operate continuously for up to 90 days on only 2 L of reagents, helping facilities reduce user interaction with longer replacement intervals. Color-coded caps allow for a simplified reagent-change process, eliminating spills on the instrument, floor, or operator clothing, while redesigned flat-bottomed bottles improve stability. Unplanned downtime is reduced by predictive diagnostic tools using Hach’s Prognosys technology, alerting operators before there is an issue and walking them through the steps to correct it. A built-in help function allows operators to interpret all warnings, errors, and reminders quickly. Frequent bulb replacement is eliminated with a long-lasting light-emitting diode illumination source, and visibility is enhanced on the 5.7-in. liquid-crystal color display.

Nanocoating

DuraSeal Coatings Company has  tested its DS200 nanocoating successfully, confirming a 38% pressure-drop advantage for coated downhole tubing vs. uncoated tubing (Fig. 3). All tests were conducted at the Southwest Research Institute flow-loop in San Antonio, Texas, USA. The test setup included a 30-ft-long pipe section of each tubular diameter, coated and uncoated, in a closed high-pressure-gas loop. -Transmission-grade natural gas was used as a test medium, with pressure capability to 1,000 psig and flow rates ranging from 100 to 1,000 actual cf/min. Each tube was tested individually at a constant 1,000-psig upstream pressure at 70°F over a minimum of five distinct flow rates from 100 to 1,000 actual cf/min for 3½-in. tubing. Redundant gauges were used to ensure test accuracy and efficacy. The lower pressure drop translates into less pumping energy and higher flow rates, thus reducing costs for gas producers.

Multisample Extraction Process

ALS Petrophysics has developed its -solid-phase multisample extraction method, CEPSat, as an oil-recovery tool that can help inform critical decisions for operators within the heavy-oil arena. CEPSat has proved to be more efficient than other commonly used processes such as the single–sample solvent–distillation method, Dean-Stark (DS), and low-field nuclear magnetic resonance. CEPSat applies existing technology, taken from the forensics and pharmaceutical industries, for the determination of oil (So) and water (Sw) saturation (Fig. 4). This technique gives clients access to profile Sw/So data taken across higher sample sets over a cored interval and in a shorter time frame than that required by standard DS measurements while using a smaller laboratory footprint. With measurements -possible up to every 1 cm, the generated Sw/So profile allows specific areas of interest to be identified within an interval and to be sampled for further DS analysis. The technology is portable, requires one medium-sized fume cabinet and a single operator, and can run up to 80 samples in one sitting.

Maintain-in-Place Products

Moyno’s EZstrip products are aimed at more efficiently maintaining in place progressing-cavity (PC) pumps and associated products. The EZstrip line currently comprises a transfer pump, a cake pump, and a grinder (Fig. 5). The EZstrip Transfer Pump provides efficient disassembly, deragging, and maintenance of a PC pump in place, reducing maintenance time by more than 93%. It features a split coupling, offering direct access to wear parts and rotating assemblies without affecting operational parameters. The EZstrip Cake Pump features a specially designed feed chamber that can be disconnected to allow access to the rotating assembly. The rotor can be separated from the conveyor, allowing removal of the rotor and stator all within its own assembled length. The EZstrip TR Munchers family of grinders offers a competitive solution to solids grinding and sludge conditioning. These grinders all house a quick-release access port, allowing the cutter assembly to be maintained in place without removing the equipment, thereby reducing maintenance time.

Hybrid Drill Bit

Baker Hughes has announced the successful deployment of  the Hughes Christensen Kymera hybrid drill bit for Statoil in order to improve rate of penetration (ROP) and drilling performance in an appraisal well in the deepwater Logan field. This was the first time a large-diameter Kymera bit was run in the Gulf of Mexico. A 26-in. Kymera hybrid bit with 19-mm cutters and premium metal face seals was used to drill the 26-in. vertical section through sediments and salt to section total depth, enabling 22-in. casing to be set 450 ft deeper than the well’s original objective. The ROP was improved by 26% compared with the nearest offset. The Kymera hybrid bit combines polycrystalline-diamond-compact (PDC) and roller-cone-bit technologies for smooth drilling, effective torque management, and precise steerability through the most-complex formations (Fig. 6). The bit leverages the cutting ability and continuous shearing action of PDC bits along with the strength and stability of roller-cone bits. The combination helps the Kymera bit achieve improved performance, superior tool-face control, and higher overall ROP for more footage than either a roller-cone or a PDC bit.

Microseismic Data-Processing System

Schlumberger has introduced a new moment-tensor-inversion service that provides enhanced analysis of the dynamics of hydraulic-fracture propagation (Fig. 8). This service helps improve well-completion designs through an increased understanding of natural- and induced-fracture characterization in oil and gas reservoirs. When applied in unconventional reservoirs, the moment-tensor-inversion service provides information about the orientation, volume, and proppant placement associated with the hydraulic fracture. The proprietary processing used in the moment-tensor-inversion service accounts for anisotropy. As the microseismic–monitoring industry moves toward quantitative source inversion, the rigorous incorporation of anisotropy in unconventional-reservoir models becomes more important to accurately process and interpret the valuable information contained in microseismic signals. The moment–tensor-inversion service has been field tested on microseismic projects in North America. Analyses of moment-tensor-inversion processing during field trials in the Permian Basin confirm that the incorporation of anisotropy leads to improved interpretation of microseismic data and to more-robust geomechanical models.

Wireline-Monitoring System

Specialized Oilfield Products has developed a digital–sensor monitoring system that can extend the life of wireline through continuous surveillance. Traditionally, wireline integrity has been inspected manually in stages, using an eddy-current flaw-detection system and the naked eye or wireline has been replaced after a fixed period by operators irrespective of whether a defect exists. The new system includes an electronic sensor that is attached to an eddy-current flaw–detection system (Fig. 9). The sensor accurately pinpoints any integrity issues as the wireline test is run and stores the information on a secure digital card. The information can then be viewed on a monitor, clearly indicating the exact location of any defect in the wireline. The system can be deployed on all standard wireline sizes currently used in the oil and gas industry, and a permanent record of the wire’s integrity is recorded.

Pressure Comparator

Crystal Engineering has introduced the new GaugeCalHP pressure comparator for test and calibration applications up to 15,000 psi. The device is suitable for use with water or oil, either in the field or in the laboratory, and is compatible with most large-sized pressure gauges. The GaugeCalHP is designed with crystal pressure fittings (CPFs), a reservoir relief valve, and other features that enhance its safety (Fig. 10). The CPF system adds an O-ring sealing system that permits leak-free connections without tools and a self-venting weep hole that alerts users before they disconnect from a pressurized system. CPFs and hoses come with an industry-first 4:1 safety factor. Additional features of the GaugeCalHP include a fine adjust usable at 15,000 psi, a connection fitting with quick alignment–swivel capability, and a pivoting manifold that rotates to fit large-sized gauges. To increase stability, the device’s reservoir can be used to quickly add a small amount of pressure to bleed air out of the CPF weep hole.
