Lower operating temperatures in ESPs Thermoline, from Duoline Technologies, is a concentric tube featuring a specialized grout system that provides a highly effective insulating layer between produced fluids and the surrounding environment. The product enables the lowering of operating temperatures for electrical submersible pumps (ESPs). Shrouded ESP motors can overheat and scale up, even with relatively mild, static bottomhole temperatures. Rising tubing fluids can transfer waste heat to the cooler falling annular fluids via the tubing wall above the ESPs, and this adverse heat cycle buildup can cause the motor thermal rating to be exceeded and result in scale precipitation. Tests with Thermoline, in a shrouded ESP application having a long perforated interval, resulted in temperature drops of 50°F.
Rig tracking system The RigTrac system from Delta Wave Communications is based on the Inmarsat satellite network. While GPS tracking is nothing new, RigTrac offers a unique feature, in that constant monitoring is not required until an asset moves from its designated location. Once out of its designated location, alerts are sent via SMS to cellular phones and e-mail, as well as the company’s on-line monitoring facility, which includes the GOM block chart. The system was beta-tested during the 2005 hurricane season in the Gulf of Mexico, and it performed with zero errors. System installation does not require any special training and can easily be performed by rig personnel. A small shoebox-sized device is installed onboard the rig with a clear line of sight to the horizon. Once the unit is powered up, the GPS coordinates are captured by the RigTrac system, and these are then used to "geo-fence" the rig (a virtual boundary or fence set up around it). The RigTrac unit sends in a position report every morning to verify that it is within its geo-fence and working properly. If the rig moves outside of its assigned area, an alarm signal is immediately relayed to Delta Wave, and is then displayed on the website map. Notifications are also sent to e-mail addresses and cellular telephones, if desired. The standard report interval is one report per hour until the rig is back on location.
Cable and control line protector clamps Downhole Products, a manufacturer of specialist oilfield equipment for the upstream oil and gas industry, has introduced the Grippy line of cross-coupling ESP cable and control line protector clamps. These cable protectors convey and secure ESP cable and control lines in and out of wellbores quickly, safely and efficiently. The product’s contoured, slick features prevent serious hang-ups downhole, and are engineered to eliminate compression-induced damage to ESP conductors and control line cables. Manufactured to ISO 9001-2000 quality procedures, the cable protector assemblies are available for all standard tubing and casing sizes, and coupling connections ranging from 27/8 in. through 7 in. They can also be configured for both round and flat ESP cables, sub-surface safety valves, chemical injection lines and fiber optics.
Cost-effective formation testing Fundamentals of Formation Testing, a new reference book produced by Schlumberger for oilfield professionals, illustrates state-of-the-art formation testing technologies with field examples, from well testing applications to test design, operations and interpretation. The book discusses dynamic properties of reservoir rock and produced fluids, and pressure sensor technology, in addition to well testing operations and data collection, test design considerations, reservoir fluid sampling and static pressure applications. Discussions of transient testing interpretation principles and advanced applications of transient testing reinforce the value of formation testing. Testing interpretation software is also discussed. Each chapter includes references to significant technical papers for readers seeking additional information. Fundamentals of Formation Testing is the first installment of the Principles of Log Interpretation reference series, which replaces the classic Log Interpretation Principles/ Applications books published in 1989.
Power module Cummins Inc. announced the production launch of its new 1.1-MW SCR Drill Module. The 1571-kVA/600-V power unit consists of a Cummins KTA50 engine, rated at 1,470 hp (1,096 kW) at 1,200 rpm, which is fully integrated with an AVK DSG86L1-6 generator and is suited for the durability, reliability and power density requirements of SCR power modules. Fuel costs are expected to be 3 – 5% lower than competitive products. The KTA50 engine is backed by Cummins’ Mobile QuickServe program. The company also offers the KTA50 engine separately from the SCR Module to allow drill owners to couple the engine with the generator of their choice.
Wellbore stability analysis Petrospec Technologies, Inc., has released EQUIPOISE 2006, software for real-time pore pressure and wellbore mechanics prediction and analysis while drilling. The new release includes modules for real-time analysis of wellbore stability criteria and formation properties, as well as integrated Internet security for real-time updates at remote network servers. This allows wells to be simultaneously monitored in real time at the office, at the wellsite, or at any location with Internet connectivity. The complex interaction between formation fluids, rock strength and stress must be accurately modeled with changes anticipated in advance of drilling. The software uses drilling data, such as resistivity, gamma ray, sonic shear and compressional slowness, geochemical and other well and formation data, to provide real-time analysis of wellbore stability condition and potential failure modes. These stability calculations, coupled with the company’s automated remote network server update service, allow monitoring of wellbore stability, pore pressure and fracture gradient analyses from any location with network connectivity. EQUIPOISE 2006 is a browser application, so users do not need to install the software on their computer, providing more data security.
LWD measurements in slim boreholes PathFinder Energy Services offers the Slim Density Neutron Standoff Caliper (SDNSC) system, an LWD system that provides real-time and memory recorded bulk density, photoelectric index, neutron porosity, density porosity and ultrasonic caliper measurements. This LWD system, with a nominal collar size of 43D4 in., can perform accurate and reliable measurements in hole sizes from 5 in to 71D2 in. The tool’s density/ neutron/ caliper sensor packages are housed in a non-magnetic drill collar. A separate, upper LWD battery collar provides power, and also puts the density and neutron measurements closer to the bit. The tool acquires data, then communicates to a telemetry controller via an internal bus. The data is then sent to the surface via mud pulse telemetry. The system processes and stores all measured and calculated data for customer distribution and presentation in various log formats. It has a borehole logging capacity of over 300 hours, and can operate in flowrates up to 375 gal/min. It is modular and can be configured anywhere in the LWD BHA, and has a dogleg severity of 30°/100 ft while sliding, 15°/100 ft while rotating. The tool is rated to 25,000 psi and 350°F (175 °C).
