TranscendIn your hands: a full range of openhole sand management services

Transcend

Fueled by the evolution in drillingtechnologies and the increasing number of longer, more highly deviated, and horizontal wells, themarket for openhole completions has expanded. With this expansion,the need has grown for sand management services that canaccommodate any type of openholecompletion, anywhere in the world.

Schlumberger Transcend integratedservices are designed to preventsand production—from the identifi-cation of potential sand problemsthrough the final stages of the completion process, and all theassociated challenges in between.These services include screens andinflow control devices, integratedwater packing technologies,Alternate Path† gravel packing sys-tems, and reservoir measurements

obtained in real time—all providedwith the multidisciplinary support ofSchlumberger sand managementexperts. Combining comprehensiveservices and Schlumberger expertisecan help you prevent sand produc-tion and maximize productivity andhydrocarbon recovery.

Along with the growing openholecompletion market come challengesrelated to complex environments.Deepwater developments, uncon-solidated sands, and unstableformations with reactive shalescreate difficulties related to gravelpacks that require creative solutions.The Transcend family of servicesmeets these challenges through itsfull, flexible portfolio of highly reliableinstruments that facilitate reservoirmanagement and prolong the life ofthe completion.

Reslink screens and inflow control devices

Screens, one of the main elements of sand control completions, arespecially designed to block formation sand while allowing formationfluids to be produced. In combination with inflow control devices,screens can be used to control production throughout an openholesection, particularly in long horizontal completions. Correctly applied,these devices help ensure uniform production and eliminate coning,which can reduce a well’s productive life. The broad SchlumbergerReslink* sand screen portfolio includes robust and reliable sandscreens for stand-alone frac pack and gravel pack applications, aswell as inflow control devices for producer and injection wells.

AquaPac integrated water packing technologies

Water packing has become the most widely accepted method ofgravel pack for openhole completions. The Schlumberger AquaPac*system is based on years of experience and expertise in fluids andtool technologies. The process requires thorough preparation andmeticulous implementation to ensure success. The entire cycle—design, execution, and evaluation—is supported by software withintegrated modules for tool and pumping calculations, simulations,and optimal treatment in both vertical and horizontal wells.

OptiPac Alternate Path gravel-pack system

The OptiPac* Alternate Path gravel pack system is designed to over-come the challenges of long horizontal intervals and multiple-zonecompletions. The Alternate Path system is the optimum choice foropenhole gravel pack completions in extreme conditions, includingformations with low fracture gradients and highly reactive shale environments. A pioneer in the industry, Schlumberger has thelongest and most extensive track record with alternate path systemsin openhole completions. Among the most recent offerings are innovative technologies for zonal isolation and control.

IntelliPac measurements in real time

As a well is produced, reservoir conditions inevitably change.Recognizing and reacting quickly to these changes in real time isnecessary for maximizing well performance over time. Detailedmeasurements in real time—a crucial component of reservoir management—help identify the critical changes, such as prematurewater or gas breakthrough. Schlumberger provides IntelliPac* real-time measurement capabilities that begin with sand managementand support reservoir management for the life of the well.

Sand management—an integrated approach, a common goal.

Transcend sand management services can be used separately or in combination,according to the requirements of a well, reservoir, or project.
