Optimized rotary drilling performance and minimized bit wear
Schlumberger PowerPak steerable motors offer high performance drilling and predictable trajectories. Over three decades of knowledge and experience in directional drilling were utilized to engineer the motor components with a focus on reliability. The PowerPak motor is composed of four sections including the top sub, power section, surface adjustable bent housing, and bearing section. The top sub can be a standard crossover, dump valve, float sub, or flex sub. Dump valve or float sub features...
Automatic background calculation reduces risk due to negligence
The real-time Anti-collision Smart Alarm provides a resource to detect wellbore collision dangers while drilling. As with other components of the Smart Alarm system, the anti-collision alarm operates in the background to enable the Schlumberger engineer to perform various duties while continually monitoring possible collision scenarios. The application performs travelling cylinder calculations to compute separation distances between the current well and previously selected offset wells. Offset...
Improved penetration rate with efficiency log
The MEL Mechanical Efficiency Log is a realtime interpretation technique to evaluate bit efficiency, tooth flatness and in-situ strength of the formation. The method is intended to be used in formations which behave plastically and are drilled by a gouging or scraping action of the bit. Suitable drilling combinations include series 1 and series 2 bits in shale, claystone, or silt formations. Bit efficiency is traditionally evaluated by analyzing surface measurements of weight on bit and torque....
Improves the geosteering process with Atbit Inclination Measurement
Traditional measurement while drilling technology provides direction and inclination D amp I data which is typically located 40 to 60 feet behind the bit. The distance makes directional drilling analogous to driving a bus from the back seat. D amp I data must be extrapolated from the MWD collar to the bit. Undoubtedly, gross exaggerations are made in steering which result in unnecessary undulation and tortuosity in the well path. The Schlumberger AIM At-bit Inclination Measurement tool provides...
Aids in slot management and increases production per wellhead
Multilateral Drilling and Completion Services A multilateral well is defined as a single well with multiple branches extending from the main wellbore for use in exploration, development, or reentry into an existing well. It may be as simple as an open hole sidetrack or as complicated as a multiple lateral well with several sublateral branches. Typical configurations include multibranched wells, forked wells, wells with several laterals stemming from either a vertical or horizontal wellbore,...
Internal and external pressure measurement
The VIPER system, a key element of Schlumberger's fully integrated Coiled Tubing Drilling Services, is specifically designed to access bypassed reserves and extend production in underbalanced, short radius and through-tubing reentry drilling applications. The wireline controlled VIPER tool comprises the multifunctional measurement and orientation component of the bottom hole assembly BHA . The tool offers rapid downhole data updates for quality decision making, as well as, on-bottom orientation...
Reduced cost with reentry drilling
The term short radius is used to define the radius of curvature in horizontal wells. Schlumberger short radius drilling techniques are capable of drilling curves down to a 40-ft radius which corresponds to a dog-leg severity DLS of 1437100-ft. The technique is accomplished with specially designed PowerPak steerable motors. The motors contain unique features which include flexible articulations and precise three-point curve contacts below the power section. Short radius drilling provides the...
RowrerPli
Detailed plots and reports are performed to visualize the anti-collision analysis. The options include both spider and travelling cylinder plots. Customized spider plots include a plan view of relevant wells with color-coding to indicate proposed and surveyed wells. Travelling cylinder maps provide a polar plot centered on the planned well displaying the intersection of offset wells. The BHA Editor application provides tools for creating complete drillstrings and wellbore geometries to be used...
Improved weight on bit
Drilling geologically maximizes drain hole exposure to the reservoir. The GeoSteering tool incorporates drilling and evaluation measurements into a standard Schlumberger mud-lubricated steerable motor. The GeoSteering tool provides the directional driller real-time, near-bit measurements to keep the wellbore within the reservoir. The results are maximum pay zone footage, improved production per foot drilled and lower completion costs. The primary components of the GeoSteering tool include the...
Maintains production and ROI with fewer wells by exposing more reservoir area
The well trajectory window plots planned and actual well trajectories on top of the formation cross section determined by the geosteering process. The formation layers are referenced to true vertical depth from offset well profiles. The cross-sectional view of the geological layers graphically display wellbore position with respect to reservoir boundaries. The GeoSteering Screen eliminates expenditures wasted on directional wells which successfully follow a geometric plan but miss the intended...
One time data entry improves efficiency
Schlumberger's strategic placement of directional engineering centers DEC throughout the world provides the resources to optimize well planning. The engineering centers are staffed by knowledgeable well planners and engineers utilizing PowerPlan software to design complex directional wells. The software provides the means to analyze critical operational components involved in the drilling process. PowerPlan is an integrated suite of analytic and interpretative PC-based drilling applications....
