The complete well solution

Since its introduction to the industry, Reslink has become recognized as an innovative problem solver which offers simple, robust and reliable solutions to the industry. The company’s completion solutions offer a broad spectrum of engineering applications and products for sand control/management, inflow control for both production and injection, intelligent well completions and technical support and services.

Reslink is a worldwide supplier with established markets in Europe, North America, Middle East, Africa, and Pacific Asia. Its team consists of people with more than 20 years of work experience with leading international oil companies, service companies, R&D institutions and design and manufacturing industries. The company delivers products and services that are complete sand control solutions, and believes they must be simple for installation, flexible in application, and require minimal risks for operations.

In 1999, Reslink introduced a new wire wrap sand screen, LineSlot, that has been tested to be stronger than any other sand screen available in the market. The screens are manufactured on any casing or tubing weight and grade (between 2-3/8 inches to 9-5/8 inches) and are essentially as strong as the casing in terms of tension, bending, and compression. Over 350,000ft of screens have been installed worldwide so far, and there is not a single customer feed back on failures associated with lost sand control or plugged screen.

Apart from providing an extremely robust sand screen, Reslink employs a unique engineering methodology, which has demonstrated exceptionally good results. It has worked closely with several international operators at various locations in the North Sea, North America, Nigeria, Equatorial Guinea, Chad and Southeast Asia. Reslink's pre-selection and design processes assist clients in developing optimized drilling and completion processes that lead to outstanding performances.

Reslink LineSlot Screens are specially designed for use in open hole (OH) completions where sand control achieved without gravel packing. Standalone screen completions have become increasingly popular as a viable completion solution for horizontal wells. Reslink screens have been developed, qualified and proven in numerous well installations.

For an operator company, the LineSlot screens contribute to:

• Reduced rig time for screen installations
• Increased probability for successful screen installation
• Optimized production technology solutions
• Increased completion longevity (erosion and corrosion resistant)

The robust single wire wrap sand screen is designed to be used in vertical, deviated and horizontal open-hole completion of oil, gas and injection wells. It can be used either in standalone or gravel pack and frac pack completions. Its features include:

• Unique shrink fit design and process controlled manufacturing process
• External forces on screen are transferred to and taken up by base pipe
• Torque, tensile, collapse and bending data equivalent to casing
• Heavy duty 316L and Incoloy 825 screen wire materials
• No welding on base pipe material (screen wire is shrink fit to base pipe)
• Handling and installation using conventional casing equipment
• Well suited for short radius well bore. Maintains sand control at 90º/100 ft
• Consistent and accurate slot opening for superior sand control
• Base pipe size ranges from 2 3/8 inches to 10 ¾ inches

An important aspect of the LineSlot sand screen is the quality control and the verification of the wire wrap slot opening. Thereby, the client is provided the assurance that the screen being incorporated in the completion design is fit for purpose. Reslink’s ResGauge Screen Slot Opening Control and Verification System, a world first, has significantly improved and eased verification of screen quality. The photometric system has a resolution of 1µm and an accuracy of 5 µm (compared to feeler gauges in increments of 25 µm). ResGauge provides slot measurements on 100 percent of the slots, (+/- 2500 data points per joint), compared with industry standard 15-25 manual feeler gauge checks per joint (approximately five percent).

Reslink’s ResFlow is a direct wrap-on pipe sand control screen with a nozzle based Inflow Control Device (ICD) designed for optimization of production and increasing recovery from production and injection wells. The purpose of ResFlow is to generate a controlled pressure drop between the annulus and base pipe thereby achieving a uniform inflow profile along the entire completion interval. This allows the ResFlow completion to accomplish the same regulation purpose as a surface-controlled smart well solution, but with reduced risk, less complexity and lower cost because there is no surface equipment required.

It is built upon the successful LineSlot direct wrap-on pipe sand control screen, and consists of screen wrapped on un-perforated base pipe with a nozzle based ICD located at the end of the screen (Figure 1).

ResFlow postpones water/gas breakthrough in the heel of the well or in highly permeable layers by restricting the flow rate from the zones with high flux. When water or gas breaks through, ResFlow will decrease the high flow rate of these phases and stimulate the zones with low flux by maintaining the driving pressure for the oil in the rest of the well. Designing the ICD pressure drop according to the anticipated reservoir characteristics, enables the ResFlow completion to regulate flow variations, despite limited knowledge of where the permeability variations exist along the well path.

The unique interaction between ResFlow and the reservoir affords a self adjusting production management system integrated with sand control. Fluids enter the screen and flow between the axial wires and the un-perforated base pipe into the ResFlow ICD housing, before passing through the nozzles and into the base pipe (Figure 2).
