Multiple wellbores from a single location

Grey Wolf Inc. has introduced a new fit-for-purpose drilling system, PaDSRig (Production and Drilling System), specifically designed for drilling multiple wellbores from a single pad location. Pad drilling minimizes environmental impact because it allows multiple-well access to larger areas and targets beneath sensitive surface environments such as lakes, towns, national forests, parks and wildlife areas. Combined with directional drilling techniques, multiple-well pad drilling can reduce initial habitat disturbance by as much as two-thirds or more. Engineered and manufactured in Houston by IDM Group, the drilling system incorporates IDM’s QuickSkid pad drilling technology, which features the ability for the rig to skid on a rail track in single- or bi-directional planes from the initial well to other producing wells on the pad. The PaDSRig 109 has a drilling depth capacity of 18,000 ft. The drilling structure can skid up to 140 ft in one direction and 10 ft in another direction from the initial well location to allow simultaneous drilling and production operations. AC technology enhances drilling control and improves fuel efficiency. It features a 28-ft-high drilling floor, 375-ton block and 375-ton hook load rating, and is operable in harsh environments down to -20°C.

Vector drive

Wood Group ESP has developed the new Vector VII drive, designed for oilfield pumping applications. It has a number of features not available on most drives, such as an operator control panel with a large, high-resolution, full-color-graphics display that is easy to read in bright light. Its software integrates operating information, downhole well parameters and graphical data into a common display, eliminating the need to scroll through several screens. A digital circular ammeter is displayed on the operator panel, eliminating the need for a mechanical circular ammeter for chart recording. Some 20 operating parameters are periodically sampled and stored in memory, and can be shown graphically on the operator panel or downloaded for analysis. Remote user interface, monitoring and control functions are also supported. The Vector VII is provided in a Nema 3R-rated outdoor enclosure, making it suitable for indoor and outdoor use. All electronic components are inside a sealed (Nema 4) section of the drive enclosure, allowing it to operate in temperatures from -40°F to +122°F.

Coiled tubing services

Schlumberger announced the release of the ACTive family of live downhole coiled tubing services, which provide interventions to elevate the performance of coiled tubing operations in various well configurations. A ruggedized high-bandwidth fiber optic cable deployed inside the coiled tubing string connects bottomhole sensors with surface monitors and controls, allowing engineers to measure and interpret downhole events in real time. Continuous monitoring provides instantaneous insight and quantitative feedback on the progress of downhole treatments, and alerts to any deviation from the job design. The ACTive portfolio is composed of six services: ACTive Matrix monitors injection rates, downhole pressures and temperatures of matrix treatments to maximize fluid penetration and coverage, enhance diversion and optimize treatment volumes; ACTive Cleanout uses differential pressure readings to avoid formation damage and minimize the number of trips and operating time, while ensuring thorough removal of fill; ACTive Perf achieves accurate depth control and target coverage in a single run while controlling hydrostatic balance to minimize formation damage; ACTive Isolation ensures efficient, on-depth setting of isolation devices in a single run, controlling differential pressure across the sealing elements to ensure their integrity; ACTive Lift improves the efficiency and results of nitrogen lift jobs by continuous monitoring and balancing of wellbore pressure while avoiding solids production; and ACTive Profiling enhances all ACTive services by including distributed temperature surveying (DTS) to provide a 3D time/temperature profile across the entire well to monitor performance.

Wireline tools for coiled tubing

AnTech Ltd. has announced the latest additions to its range of “Wireline in Coiled Tubing” tools: the new collector bulkhead and a 27/8-in. logging head featuring seven conductors. The collector bulkhead provides an improved means of connecting wireline to surface. Installation and connection of the wireline are simplified-the electrical connections are situated on rails so that one person can carry out installation and maintenance. The new bulkhead is available in both single- and seven-conductor configurations to suit customer requirements, including Atex options. The addition of a 27/8-in. logging head to the 111/16-in. and 21/8-in. versions provides customers with a seven-conductor option for running video or openhole tools. With their modular design, the tools can be manufactured to meet customer-specified connections and cable sizes. The 21/8-in. and 27/8-in. tools are available with a mechanical release featuring precision shear pins or an electrical release for controlled release. The logging heads can also be used in highly deviated and horizontal wells where wireline is not an option. Suitable applications are open and cased-hole logging and perforating.

Fully integrated EM system

Electromagnetic Geoservices ASA (EMGS) announced the launch of Clearplay, the first fully integrated EM system, providing seamless, end-to-end EM services and products in support of hydrocarbon exploration. The Clearplay portfolio consists of three distinct services-Clearplay Find, Clearplay Test and Clearplay Evaluate. Fundamental to the system is its ability to reveal information that is intimately linked to the presence of hydrocarbons. Integrating Clearplay with the traditional exploration workflow enables a clearer and more complete understanding of the subsurface.  Clearplay Find involves towing a high-power EM source over a course grid of receivers, 2-4 km apart, and the subsequent, rapid processing of data onboard the survey vessel. It is employed in early-stage exploration, pre- or post-licensing, but can also be used to re-explore mature areas. Clearplay Test provides rapid, more accurate ranking of prospects in offshore locations, reducing the likelihood of dry wells. Typically, a prospect will be targeted by towing the EM source over receivers placed in one or more lines, or a grid, 1-2 km apart. Operators are able to achieve a better discovery rate, with the same or fewer resources, than when using traditional methods alone. Clearplay Evaluate improves certainty and efficiency in appraisal- and development-phase decision making, and improves the assessment of a reservoir’s potential following successful discovery well drilling. Typically the data is acquired by towing the EM source over and between the lines of a dense grid of receivers, 0.5-1.5 km apart. The quantity and quality of the information this generates, including 3D azimuthal data, enables the most sophisticated data processing visualizations to be used and increases the accuracy of the results. When integrated with information from other sources, such as 3D seismic, it can significantly improve the speed and accuracy of prospect appraisal, giving a more informed assessment of hydrocarbon volumes and distribution within a prospect.
