The application of advanced reservoir navigation and proactive geosteering techniques allows you to successfully drill and complete difficult horizontal and multilateral wells with increased confidence. Baker
Hughes Reservoir Navigation Services will significantly reduce unnecessary course corrections, decrease hole tortuosity and improve your penetration rates.
By maximizing reservoir contact and accurately reaching your well targets, our Reservoir Navigation
Services offer an efficient, cost-effective solution to your operational needs, allowing you to:
„ Maintain the wellbore in the pay zone and avoid reservoir exit
„ Reduce uncertainty
„ Avoid NPT-related costs
„ Lower the risk of costly sidetracks
„ Enhance completion strategy
„ Increase overall asset recovery

Our Reservoir Navigation Services assist you in all aspects of the planning and execution stages of high-angle and horizontal well drilling. In the planning phase, Baker Hughes experts use a comprehensive toolkit combining the latest in 3D-visualization and predictive-response modeling techniques.
Our precise, real-time drilling capabilities and advanced formation evaluation technologies are complemented by dynamic, interactive reservoir navigation software to keep your wellbore in the pay zone. Throughout your operation, our dedicated Reservoir Navigation Service engineers provide expert, proactive advice, giving you the confidence to make the right decisions that will increase your hydrocarbon production and recovery potential.
Our Reservoir Navigation Services provide a scaleable solution that’s applicable to all high-angle and horizontal applications— from the simplest to the most complex well trajectories.
Prior to drilling your well, our reservoir navigation experts conduct a comprehensive prewell planning and modeling process.
As an essential part of this process, we integrate multiple offset-well and digital-horizon data into a 3D geospatial model of the reservoir’s anticipated stratigraphy. Then, we incorporate proposed well plans into the model to check against structural data, ensuring all geological and drilling targets are accessible.

Structural information is exported to our proprietary reservoir navigation software, and our engineers create a predictive model that anticipates real-time tool responses to the expected stratigraphy.
Additional forward models are built to test alternative geological interpretations, qualify geological model reliability, and identify any likely weaknesses in the geological interpretation. Data from the 3D structural and well models, tool response models, and geological variance model is consolidated into a solution that will define best practices and reduce your uncertainty in the wellbore.

During an operation located in a mature, oil-over-water reservoir with an average 90% water cut, our Reservoir
Navigation Services and AziTrak ™ azimuthal resistivity measurement tool allowed our client to decrease his uncertainty about the exact location of the formation roof.
Using real-time monitoring of the geological position of the well, we successfully maintained a precise standoff from the roof of the sand body and landed the horizontal section inside the top of the reservoir. With initial production rates 48% higher than that of offset wells, our Reservoir Navigation Services provided the client with a significant increase in asset recovery and greatly enhanced future development plans.
Our Reservoir Navigation Services provide the greatest flexibility when it comes to selecting the right delivery systems for your drilling operation. When drilling your horizontal well, the key to accurate lateral placement is the ability to detect remote boundaries in real time, update the models that describe and predict the environment ahead of the bit, and make proactive decisions to keep the well in the most productive zone.

Drawing from a suite of our most advanced automated drilling system, such as the AutoTrak ™ G3 rotary closed-loop system, our steerable Navi-Drill ™ motors, and fit-for-purpose logging-while-drilling (LWD) evaluation services, we offer the capabilities to precisely drill and complete complex wellpaths with less tortuosity while both landing and drilling the horizontal section.
During the drilling phase, real-time survey and LWD data is captured and entered into the reservoir navigation software. A variety of customized plot formats is used to present the data in its geological context on both measured and stratigraphic depth scales. Prewell models are interactively linked to a selection of geological and property curtain sections, allowing dynamic, real-time updates to describe and predict the geological environment.
When indications of an approaching change in lithology or fluid contact are recognized, our reservoir navigation engineer will recommend corrective actions to avoid leaving the reservoir zone.

Baker Hughes proprietary reservoir navigation software provides an integrated solution to predictive LWD response modeling. Our fast, dynamic interpretations and interactive real-time applications allow you to make informed decisions on the precise placement of your wellbore.
In addition to our proprietary software, we use the industry’s most advanced imaging technologies to further enhance our interpretive capabilities:
„ EarthVision* 3D geospatial modeling software
„ WellArchitect* 3D well-planning software
„ CoViz* real-time 3D/4D, fully integrated data solution
*EarthVision, WellArchitect and CoViz are products of Dynamic Graphics, Inc.
Our experts can access fully interactive distance-to-bed boundary displays and azimuthal data to support your decisionmaking process. By steering close to the roof and maximizing the standoff, Baker Hughes can help you target marginal and attic reserves to increase returns.
As proven on a pilot/production-well drilling operation in the
UK, our Reservoir Navigation Services allowed the client to maintain an accurate range of distance from the reservoir roof while minimizing shale exposure. Real-time information from the AziTrak tool’s deep azimuthal propagation resistivity and azimuthal gamma-ray measurements helped our engineers differentiate between shale scours and roof shales. As a result, we were able to drill the client’s production well an average

of 23 ft above the initial plan, resulting in increased access to attic oil and increased reserves in this section of the field.
Baker Hughes Reservoir Navigation Services ultimately helped the operator drill 5,450 ft of 8½-in horizontal section to TD with a net-to-gross ratio of approximately 92.1%.
Our Reservoir Navigation Services team implements specialized software and interpretative expertise to provide real-time solutions to your drilling challenges. Whether it is at the wellsite, in your office, or via one of our BEACON ™ collaboration centers, our team is dedicated to ensuring you receive the right advice to land your wellbore in the optimum stratigraphic position and keep it there.
Baker Hughes reservoir navigation engineers use the most advanced drilling and evaluation technology to carefully plan and implement your geosteering project. Our engineers will predict and avoid potential reservoir exits to improve your efficiency and reduce the risk of NPT associated with costly sidetracks.
