StrataSteer® 3D Geosteering Service

StrataSteer 3D Geosteering ServiceSperry Drilling Services' StrataSteer® 3D service is more than just geosteering. It is the heart of our wellbore positioning service, crucial to placing a well, especially in smaller targets that often require complex well paths and more accurate wellbore positioning.

The service integrates digital 3D geological earth models, directional well plans, petrophysical models and real-time LWD sensor data into a dynamic, interactive and intuitive geosteering application. The service continues to drive reductions in planning cycle time and drilling time while increasing reservoir exposure and production.

StrataSteer Engineer

The service has been run on hundreds of wellbores, for more than 20 international clients, on five continents, and has experienced:

StrataSteer Session

  • Increased production: many wells see daily production increase in excess of 10 percent

Summary Summary Canada: Accurate Geosteering Helps to Precisely Position a Wellbore in a Cyclic Steam Application for Optimized Oil Recovery Sign in required
Geosteer a horizontal well for precise wellbore placement in the heavy oil reservoir, 2 meters (6.6 feet) above a lower shale boundary.
Summary Summary Ecuador: Slimhole GeoPilot® System and StrataSteer® 3D Service Help Save Nine Days of Operational Time and Double Production from Well Sign in required
An operator in Ecuador needed to drill a sidetrack after the loss of a well that had been drilled with conventional directional drilling tools.
Summary Summary Canada, Alberta: Real-Time Geosteering Delivers Precise Horizontal Wellbore Placement in Heavy Oil Sands Sign in required
To capture maximum reserves in the Primrose field of northern Alberta, Canada, an operator had resorted to “tagging the shale” bottom to position horizontal wells as close as possible to the base of the reservoir. The result was often a drill bit stuck in the shale, and either poor wellbore placement and lost reserves, or having to pull back and re-drill the section.
Summary Summary Egypt: Geo-Pilot® Dirigo Rotary Steerable System Delivers High Build Rate Well Profile and Saves Operator Five Days of Rig Time Sign in required
In the NRQ area of Egypt, Khalda Petroleum Company planned to drill a horizontal well targeting the Coarse Dolomite zone of the A/R “G” formation in the North Ras Qattara field. Because NRQ wells typically encounter severe changes in formation dipping while changing well direction, the primary challenge in this case would be the 8 ½-inch hole section. The plan was to land the well with an 87 degree inclination and turn the azimuth from 177 degrees to 132 degrees with continuous dogleg severity (DLS) of 5.8 degrees per 100 feet.

With a drilling program of multiple unconventional wells, an operator in Alberta, Canada has been searching for a solution to improve the economic viability of its assets to a lower cost per BOE.
Summary Summary GOM: An operator saved an estimated US$500,000 by staying completely within the target window Sign in required
An operator in the Gulf of Mexico wanted to increase production and recovery in a mature field, but was faced by two main challenges.
Summary Summary Mexico: Sperry Drilling’s New Data Compression Software Facilitates Geosteering Within Thin Reservoir while Significantly Reducing Drilling Time Sign in required
In this shale gas well in the Eagle Ford play in Mexico, the primary objective was to drill a horizontal well with maximum lateral exposure within the 10 feet (3 meters) thick production zone. The challenge was to stay in the relatively thin shale pay zone while maintaining an aggressive rate of penetration.
Summary Summary Middle East: Geo-Pilot® XL 5200 System Delivers First Single-Run Lateral in Middle East Field While Reducing Drilling Time By 3.9 Days Sign in required
Sperry Drilling’s geosteering solution combined advanced technology, tools and talent in a comprehensive approach.
Summary Summary Oman: StrataSteer® 3D Geosteering Service with the ADR™ Sensor Help Deliver Five Times More Production Sign in required
Drill a 900 meter (2,953 ft) lateral, maintaining well trajectory within the 3-5 meter (10-16 ft) thick complex reservoir.
Summary Summary Middle East: Remote Operating Centers Successfully Optimize Geosteering Efforts to Maximize Exposure in Extremely Thin Clastic Reservoir Sign in required
An operator drilling through complex shale and sand formations required accurate real-time information to navigate to a sandstone target zone of a mere three feet true vertical depth, sandwiched between two shale zones.
Summary Summary Canada: Accurate Geosteering Helps to Precisely Position a Wellbore in a Cyclic Steam Application for Optimized Oil Recovery Sign in required
Geosteer a horizontal well for precise wellbore placement in the heavy oil reservoir, 2 meters (6.6 feet) above a lower shale boundary.
Summary Summary UAE: First Geo-Pilot® Dirigo Rotary Steerable Run in UAE Lands Complex Sign in required
An operator planned the first fork-type multilateral well design in the United Arab Emirates (UAE) to be drilled from an offshore platform. The complexity of the program would require advanced geosteering capabilities to achieve maximum reservoir contact and precise placement of the forked-shape laterals with full accessibility for well intervention. The target was just 600 feet (183 meters) south of the platform and required a “pregnant lady” well profile through a very challenging shale formation where historically no directional work is recommended. With only one available platform slot, located on the northwest side, the well would first have to be nudged and turned in the 16-inch hole in order to reduce surface collision risk, and would then encounter a channel at the 13-3/8-inch casing point known to cause huge losses. In the 12 ¼-inch hole, a required open-hole sidetrack would present yet another challenge. And furthermore, the 8-½-inch lateral interval would have to be maintained within the reservoir target of just two feet (0.61 meters) in thickness.
Summary Summary Oklahoma, USA: GABI™ Motor and StrataSteer® 3D Service Provide Real-Time Geosteering Solution for Successful Well Placement in Critical Thin Bed Horizontal Sign in required
While drilling the 4,000-foot horizontal section of a 10,000-foot well in the Mississippi Lime near Alva, Oklahoma, the customer needed to maximize exposure to the 15-foot thick target formation and totally avoid the bounding shale above. Drilling into the shale above would introduce wellbore stability issues, and force the operator to sidetrack. Additionally, the operator needed to minimize the cost of the well while staying in zone. Previous attempts at drilling this zone had resulted in breaking out of the target formation, and having to pull back and sidetrack the well.

Summary Summary Middle East: Geosteering Solution Delivers Record Performance, Cuts Seven Days from Lateral Well, Saving Customer an Estimated $400,000 Sign in required
In this mature field, the customer planned to drill a lateral well located inside a restricted area. The plan was to drill the build section in 8-½-inch to land the well in the limestone “A” reservoir. Then, in the 6-1/8-inch section, to steer the lateral section inside both the “A” and “B” reservoirs. Specifically, the customer required geosteering to drill the “A” reservoir for 1,500 feet, then drop angle and enter the “B” reservoir, building to horizontal then holding angle to drill the remaining 900 feet inside the “B” reservoir.
