Our slim logging tools help you compete and grow.

The global horizontal logging market continues to grow, bringing with it new business-growth opportunities. But until now, only the largest

service companies have had access to the slim formation-evaluation tools required in order to bid on these projects and win on international RFPs.

04

Until recently, service companies that have wanted to be an important player in the horizontal/unconventional logging market have had to watch from the sidelines, with no access to a provider of high-quality, slim formation-evaluation tools with an advanced conveyance system.

With the advent of Signum Instruments’ micro-slim formation-evaluation tools, however, the competitive field has changed. Now service providers have a way to enter this new market and do so with the confidence that only state-of-the-art instruments can provide.

Our products are backed by decades of downhole-tool design and development expertise and offer unsurpassed flexibility. Our fully characterized logging tools allow you to obtain quality data and make it possible to:

• Acquire data in conventional wireline mode

• Log in real time or memory mode

• Access small-diameter wells

• Bypass trouble zones through drill pipe in high-angle wells

• Log through drill pipe in tough logging conditions

• Pump down through drill pipe to log horizontal wells

We’ve seen the need for best-in-class, slim formation-evaluation tools that service providers can access. That’s why we have now brought to market a robust tool suite that reduces NPT and offers a lower cost of ownership. By doing so, your opportunity to compete has just opened up.

During through-drill-pipe operations, Signum logging tools gain access to the open hole by passing through the bottomhole assembly (BHA). Comprised of the optional float-valve sub, deployment sub and access bit or mule shoe, the BHA makes it possible to bypass trouble zones, drill through bridges, complete reamer runs and maintain well control, all while maintaining access to the borehole. Not getting logs to bottom is no longer a problem with the Signum conveyance system.

FEATURES:

• Maintains well control

• Allows tool access to borehole

• Allows circulation and rotation capabilities

• Bypasses trouble zones

• Eliminates additional conditioning trips

ANCILLARIES

SWIVEL

Swivel enables free rotation between two sections of the tool string. Decouples tool string from the wireline or drill pipe during memory operations. This ensures minimal tool rotation, producing more consistent data.

SP SUB

The original logging tool, the SP Sub allows lithology identification and can be used as a means of log correlation. Use the SP Sub to determine bed boundaries, indicate porosity and permeability, and measure the difference in potential between the downhole electrode and a surface electrode.

CCL

Used as a means of depth control, the CCL responds to variances in metal volume, such as pipe collars and perforations.

Ancillaries

Signum Instruments’ accessories provide the flexibility you need to not only work efficiently, but also handle unforeseen circumstances should they occur. Want to make operations flow more smoothly? Save time? Prevent problems? Look no further than Signum Instruments.

24

DECENTRALIZERS

Decentralizers ensure that tools are properly posited against the borehole wall. This minimizes the effects of borehole fluids and enables the acquisition of high-quality data. Electrical feedthroughs enable the tool to be used at any point in the string, while fully collapsible springs enable easy passage through drill pipe or into the casing shoe.

CENTRALIZERS

Centralizers optimize tool position while minimizing environmental effects. With the

ability to fully collapse to a 2 ¼” diameter, Signum centralizers offer a through-tubing-capable solution for conventional, directional and horizontal well-bore applications.

KNUCKLE JOINTS

Knuckle joints enable ideal tool positioning, reduce the rigidity of the tool string and optimize weight distribution for easier maneuverability in highly deviated or horizontal wells.

SURFACE EQUIPMENT

During logging operations Signum Instruments’ MicroSlim technology collects downhole data that is then sent up-hole through the Interface Panel and recorded via the SignumLab software. During memory operations, Signum’s Intelligent Depth Tracker (iDT) enables the user to record the drilling rig’s measured bit depth against time as drill-pipe is tripped out of the hole. Merging this information with the recorded downhole data results in a log presented in standard format.

Signum Instruments’ Interface Panel (SIIP):

The SIIP is a small 2U panel which allows the user to directly interface with the downhole tools and wireline. Eight removable banana plugs provide direct access to conductors for easy continuity testing, while a selectable switch offers easy change-over from several modes including log, external power, mono conductor, safe, and test.

Intelligent Depth Tracker (iDT):

IDT is composed of a depth tracking box, rotary encoder, and deadline hook load sensor. Upon calibration the software will record bit depth, hook load, block height, and ROT. If preferred and/or available, WITS connections allow the user to plug directly into the rig’s Pason, Totco, or third-party depth tracking computer.

• Use for memory logging services

• Time based depth recording

• Easy to use software
