Scientific Drilling offers a suite of high-accuracy Magnetic Ranging services, delivering the greatest drilling precision and cost effectiveness available in the industry today.

Scientific Drilling offers Active Ranging techniques in combination with our industry-leading Passive Ranging service, MagTraC, to create a comprehensive and highly adaptable set of guidance services, which integrate seamlessly with any operation. This blended approach maximizes performance and flexibility, providing the best available solution for meeting and exceeding even the most ambitious operational and budgetary goals.

Our guidance services can be tailored to optimize production for a range of operations including frac salvage projects, steam assisted gravity drainage, coal bed methane production, and optimized lateral placement for multi-well-pad hydraulic fracture production. Scientific Drilling Staff work with you in determining the balance of active and passive ranging that will minimize non-drilling time, while maximizing drilling efficiency and rate of penetration.

STEAM ASSISTED GRAVITY DRAINAGE (SAGD)

Heavy oil drilling around the world often avails of Steam Assisted gravity drainage techniques that generally require shallow TVD horizontal well pairs to be installed in the bitumen pay zone. The precision twinning of these horizontal wells requires a relative downhole measurement of distance and direction while you drill, which can be accomplished by a number of magnetic ranging techniques. In addition, absolute positioning of shallow TVD horizontal wells is also very important when it comes to steam chamber development and optimal recovery from the reservoir. In addition, horizontal well pairs must also be placed in close proximity to vertical wells, a challenge which must be met by the deployment of survey management and at bit magnetic ranging techniques.

RELIEF WELL INTERVENTION AND PLUG AND ABANDONMENT INTERCEPTS

When surface access to a problem well is physically obstructed or cost prohibitive, eccentric hydraulic communication from a purposely drilled relief/plug and abandonment well is often required. Accessing an the problem well via a second wellbore is not without its challenges however, as uncertainly of position of both wells make locating and homing in on the target well problematic when relying on conventional surveying alone. Through a combination of advanced wellbore surveying techniques as well as industry leading magnetic ranging proximity methods, Scientific Drilling is able to identify, track and intersect a problem well in the most efficient means possible.

COLLISION AVOIDANCE

Whether by design or due to unavoidable congestion in mature fields, drilling wells often come into close proximity to existing cased wells. The unintended intersection of these wells carry a number of HSE and financial risks which ought to be minimized by all reasonable means. Scientific Drilling Offers a number of services which can be mobilized on short notice to mitigate these risks and allow the operator to steer freely in magnetically perturbed environments. In addition, the same systems can be deployed in congested environments to allow the operator to drill a well plan that otherwise would not be possible without uncertainly reducing and relative wellbore position techniques.

WELLBORE INTERSECTION

Intentionally connecting wellbores subsurface is a routine complex completion option readily available to the industry today. Subsurface wellbore intersection applications include: Coal Bed methane vertical to horizontal intersection, horizontal to horizontal well connection for pipeline crossing/utility crossing and deep geothermal wellbore connections, amongst many others. While drilling these wellbores is often routine, the relative wellbore considerations involved with connection one or more wellbores is not. Scientific Drilling offers a full suite of ranging and surveying services to address these unique challenges.

KICKOFF ASSURANCE

Kicking off from vertical in the presence of magnetic interference presents risks and well placement uncertainty issues that can often be unacceptable to the operator. By deploying one or more advanced wellbore placement and steering techniques, Scientific Drilling can provide the operator with the tools they need to allow the directional assembly to be steered freely in a magnetically perturbed congested environment. This is particularly applicable to Pad Drilling.

FISH BYPASS AND WELLBORE RE-ENTRY

Bypassing a stuck fish from an existing wellbore and successfully re-accessing open hole below the obstruction is a challenging operation to say the least. Kicking off and steering around the fish often involves dealing with magnetic interference from the fish, and subsequently using that interfering magnetic signal to establish a relative trajectory to the open hole below. Scientific Drilling can use a combination of systems and techniques to offer the operator the highest probability of success possible in bypass and re-entry operations.

GHOST HOLE DETECTION

It is becoming increasingly common, especially in mature fields, to encounter a cased wellbore whose position is either poorly defined or completely unknown. In these situations, MWD readings can become corrupt, making drilling ahead highly problematic. In such situations, Scientific Drilling, on short call out, is able to offer a comprehensive solution that will allow the MWD anomalies to be characterized and understood, thereby allowing drilling operations to resume, and safe bypass or relative placement to the offending wellbore possible.

CLOSE PROXIMITY DRILLING

Numerous drilling and completion applications call for maintaining a close proximity to one or more cased wellbores. Proximity to a nearby wellbore can be monitored and maintained with various levels of accuracy, with one or more services that range in cost effectiveness and efficiency. Scientific Drilling can offer one or more magnetic ranging and surveying techniques, tailored to meet the most ambitious cost and efficiency targets.
