Quick Core 76™ Information

Features

Quick Core 76™ is a slim hole wire line coring system. Developed to deliver 3” (76mm) core in 6 1/4" (159mm) hole size at depths under 1000m. Utilizing common drill pipe allows the system to be used on any type of drilling rig. The system specializes in unconsolidated formations utilizing a disposable inner tube that houses the core. The Quick Core 76™ is equipped with a drill ahead feature capable of drilling out casing shoes, between core points, or to TD the well all without tripping the drill string.

Specifications Overview

As projects grow there was a need to develop a better slim hole coring system. Historically, core size was small in available systems and core length was kept short due to equipment restrictions. The need to develop a system that could cut longer cores and achieve a larger core size in slim hole applications was needed. The result was tools capable of cutting a 76mm (3") core in 9m (30ft) lengths in slim hole well designs. The system uses a consumable aluminum inner tube that is cut and capped on surface. This tube acts as a container from the core and leaves it in an undisturbed state until it arrives at the lab for analysis.

Quickcore 89™ Information

Features

QuickCore 89™ is a wire line retrievable coring system that was designed to deliver "Conventional Coring" diameter and length core from almost any depth. The system will deliver 3 1/2" (89mm) core in up to 120ft 36m intervals from a maximum depth of 22,000' (6700m). A multitude of inner barrel assemblies are available to ensure maximum core quality is achieved. Anti-milling is standard on all inner barrels assemblies as well as the drill ahead feature.

Specifications Overview

As markets changed and the need for coring deeper reservoirs was increasing the separation between conventional coring and wire line coring became apparent. Wire Line coring tools were limited to 30ft (9m) and at depths over 5000ft (1500m) only a 3" (76mm) core was obtainable. There was a need for delivering a larger core size in longer sections to surface via wire line. Our aim was to deliver wire line core that was comparable to core that was cut conventionally. The result was a set of tools capable of cutting 3 1/2" (89mm) core up to 120ft (36m) in length. The tool offers a variety of containerization options and offer additional features such as pressure coring, oriented coring, etc. All of these options are available in well bores of 7 7/8" (200mm) and up.

QuickDrill™ Information

QuickDrill™ enhances the efficiency of a wire line coring system by lowering a bit into the center of the core head creating a full hole drill bit. The QuickDrill™ can be used to drill out the casing shoe, drill to core point, or TD the well without tripping the drill pipe. The center bit is lowered into place via wire line and can be removed and reinstalled multiple times in the same well bore without tripping drill pipe.

Benefits

QuickDrill™ is a feature that saves the customer valuable time when cutting multi zone cores or when utilizing top set casing. QuickDrill™ transforms the core head to a full hole drill bit. The senter portion of the bit is lowered into place via wire line. The center portion of the bit is oriented exactly to the core head to ensure bit balance is maintained. QuickDrill™ is used just as any standard drill bit would be and when the drilling is completed it may be removed via wire line in order for the coring operations to continue. This feature is most commonly used to TD the well bore. The QuickDrill™ bit can we set in place via wire line in minutes and the over hole necessary for logging can be achieved immediately eliminating a trip out to lay down the coring BHA and a trip back in with a standard drilling BHA. The QuickDrill™ bit can be set and removed an infinite amount of times in a single well bore. To switch from coring to drilling does not require any drill pipe to be tripped and circulating operations may continued while the bit is being set or retrieved.

QuickCapture™ Information

Wireline Retrievable Pressure Core

Core quality is critical when attempting to assess the risks, economics and potential success of an exploration program. This makes the collection of pristine in-situ core samples using an advanced technology extremely valuable when determining the mechanical and material properties of a target reservoir.

The revolutionary technology behind QuickCapture™ allows 100% of all in-situ gases and liquids to be collected at safe working pressures, giving a complete and accurate picture of the reservoir to guide productivity.

The system has been deployed effectively in conventional and unconventional formations and delivers the largest diameter and longest cuts of pressurised core currently available.

Running on Corpro’s game-changing QuickCore™ wireline coring platform, operators can choose to take conventional wireline or pressure cores through multiple zones while switching back and forth without tripping the drill string for value added, low risk coring.

Features

• Large 3” (76mm) diameter core
• Lengths up to 10’ (3m)
• Safe working pressure
• Wireline retrievable with QuickCore
• Pressure and temperature transducers

Deliverables

Operates in conventional or unconventional wells. In addition to standard core analysis data, QuickCapture™ can deliver enhanced reservoir data, some of which could not be acquired otherwise:

• OOIP – Original Oil In Place
• OGIP – Original Gas In Place
• GOR – Gas/Oil Ratio
• Direct measurements of saturations
• Gas content with no lost gas
• Pore pressure
• Reservoir fluid analysis
