• Optimized lateral placement for Multi-well pad hydraulic fracture production.

Scientific Drilling employees work with you to determine the balance of active and passive ranging. Meanwhile, minimizing non-drilling time while maximizing drilling efficiency and Rate of Penetration (ROP).

RELIEF WELL INTERVENTION AND PLUG AND ABANDONMENT INTERCEPTS

When surface access to a problem well is physically obstructed or restrictive, eccentric hydraulic communication from a purposely drilled relief/plug and abandonment well is often required.

Accessing the problem well via a second wellbore is challenging. However, the uncertainty of both wells’ positions makes locating and homing in on the target well problematic when relying on conventional surveying alone.

Scientific Drilling can identify, track, and intersect a problem well by the most efficient means possible. The process involves advanced wellbore surveying techniques and industry-leading magnetic ranging proximity methods.

WELLBORE INTERSECTION

Intentionally connecting wellbores subsurface is a standard option available to the industry today. There are various Subsurface wellbore intersection applications. The applications include Coal Bed methane vertical to a horizontal intersection, horizontal to flat 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 issues are not involved with connecting wellbores. Scientific Drilling offers a full suite of ranging and surveying services to address these unique challenges.

COLLISION AVOIDANCE

Whether by design or due to unavoidable crowding in mature fields, drilling wells often come close to existing cased wells. The unintended intersection of these wells carries several HSE and financial risks that are to minimize. Scientific Drilling Offers several services that offer opportunities to mitigate these risks. For instance, allow the operator to steer freely in magnetically troubled environments. In addition, crowded environments can use the same systems. In other words, to enable the operator to drill a well plan that otherwise would only be possible with unclear reduction and relative wellbore position techniques.

CLOSE PROXIMITY DRILLING

Numerous drilling and completion applications call for proximity to one or more cased wellbores. Proximity to a nearby wellbore can be monitored and maintained with various levels of accuracy. For instance, observe one or more services that are cost-effective and efficient. Scientific Drilling can offer one or more magnetic ranging and surveying techniques tailored to meet the most ambitious cost and efficiency targets.

KICKOFF ASSURANCE

Kicking off from vertical in the presence of magnetic interference presents risks and well-placement uncertainty issues. These issues can often be unacceptable to the operator. By deploying one or more advanced wellbore placement and steering techniques, Scientific Drilling can give the operator the tools they need to allow the directional assembly to be steered freely in a magnetically overcrowded environment. As a result, it is particularly applicable to Pad Drilling.

FISH BYPASS AND WELLBORE RE-ENTRY

Bypassing a stuck fish from an existing wellbore and successfully re-accessing an open hole below the obstruction is challenging. Kicking off and steering around the fish often involves dealing with magnetic interference from the fish. Subsequently, that interfering magnetic signal establishes a relative path 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 to encounter a cased wellbore whose position needs to be better defined or completely unknown. In these situations, MWD readings can become corrupt. Therefore, drilling ahead can become highly problematic. In such cases, Scientific Drilling can offer a comprehensive solution allowing the MWD differences to be characterized and understood. Above all, we enable drilling operations to resume and make safe bypass or relative placement to the offending wellbore possible.

STEAM ASSISTED GRAVITY DRAINAGE (SAGD)

Heavy oil drilling worldwide often helps steam-assisted gravity drainage techniques. Usually, they require shallow TVD horizontal well pairs 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. As a result, we accomplished several magnetic ranging techniques. In addition, the absolute positioning of shallow TVD horizontal wells is also critical regarding steam chamber development and optimal recovery from the reservoir. In addition, horizontal well pairs must place near-vertical wells. At-bit magnetic ranging techniques are needed, which is a challenge.

PUNCHOUT - ROTARY MAGNET WIRELESS GUIDANCE FROM SCIENTIFIC DRILLING

Unlike all other downhole magnetic units on the market, the Scientific Drilling Horizontal Directional Drilling guidance solution (PunchOut) does not create an artificial magnetic field. However, on the surface, use wire loops. Instead, it creates a magnetic field downhole using a rotating rare earth magnet. The rotating rare earth magnet is simple and durable. The flow of the drilling fluid spins it.

Most importantly, it also powers the mud motor. The rotating magnet requires no batteries or external power. As the rotating magnet turns, it creates an alternating magnetic dipole field.

The AC magnetic signal produced by the downhole rotating magnet is detected on the surface. Therefore, using a compact hand-held sensor unit. The resulting magnetic field the surface sensor receives has all the navigational advantages of the wired AC system. But eliminates the need for downhole and surface wires. In addition, it instantaneously transmits the data to the guidance computers. Scientific Drilling International’s rotating magnet solution provides all the guidance advantages of the commonly available AC system. In conclusion, eliminating all wires saves up to 75 percent of rig time.
