Value Proposition
ZerLux is developing technologies that will dramatically advance well production capabilities in the oil and gas industry. It provides a cost-effective solution for an array of subsurface applications, particularly in the offshore market, through scale removal and flow assurance, enhancing oil recovery in new, old, underperforming, damaged or even abandoned wells. ZerLux’s laser technologies offer an ideal solution to some of the limitations inherent in conventional drilling and scale removal methods, and open a wide range of new possibilities.

Products
ZerLux designs integrated laser-driven applications, using proprietary, developed, tested and validated technology, forged from more than 15 years of industry expertise. Initiating advancements in downhole laser application technology, the company is in the process of creating laser technology solutions for lateral drilling and scale removal.

Hard Scale Removal Laser (SRL) Technology
Hard scale deposition in pipelines and production tubing is one of the oil industry’s major challenges, causing premature production decline in oil fields worldwide. ZerLux’s Scale Removal Laser (SRL) for scales such as barium sulphate is offered as a working alternative to traditional methods such as milling. ZerLux’s SRL offers a 30,000-hour lifespan, with no mechanical milling components downhole. This provides a continued assurance in the reliability and productivity of the mechanism.

Why Lasers?

Conventional v. Lasers:

Lasers are non-mechanical and allow through-tubing scale removal using a small-diameter coil tubing string
They are more easily mobilized to remote and offshore environments, compared to heavy-duty current technologies, whilst achieving equivalent penetration rates
Downhole video and spectroscopy allows full real-time control of the removal process, to protect the tubing and to optimize penetration rates
The controllability of lasers allows their use in areas that current technologies cannot access, e.g. variable diameter wells.
Other advantages include:

Acid-free
Continued hydrocarbon production during procedures
Functions at extreme temperatures
No drilling or power fluid/mud
No explosives, toxic chemicals or other environmentally or logistically challenging components are required.
How?

The system comprises a surface mounted laser, coiled tubing, and an integrated bottom-hole assembly. The coiled tubing string includes an electrical and fiber optic cable. The laser changes the physical and chemical properties of the scale. It breaks up the scale into small sand-sized particles, which are removed by a combination of nitrogen pumped through the coil and the production flow.

Laser Drilled Laterals (LDL)
Why?

Laser drilling complies with industry safety standards. It fits into existing well intervention equipment such as small diameter coil tubing or umbilicals. It offers an in-situ, real-time, fully controlled procedure with video and spectroscopy feedback to the operator, with no wearing parts, no chemicals, and low maintenance, whilst maintaining formation integrity via a permeable yet strong, fused borehole wall.

How?

ZerLux, Inc. is developing an underbalanced downhole laser drilling application; a cutting-edge technology for enhanced recovery from existing wells. The system comprises a laser generator (at surface) and a specially designed directional laser drilling head attached to a coiled tubing or an umbilical system.

The high power laser tool superheats the subsurface formation, melts the rock matrix, and will remove the molten debris while the borehole is being drilled, meanwhile creating a durable borehole wall of adjustable permeability.

LDL is especially well suited for drilling laterals from existing wells in a single work phase, drilling through the casing, cement, and the formation as well with one tool in and out. No whipstock is required and no mechanical force is required to drill.

Multiple short-radius tightly controlled laterals can be created with each one up to 80 feet in length.

LDL is a highly versatile technology with a range of potential applications in the following fields:

Low-cost access to otherwise bypassed reserves
Increased productivity, especially from low permeability reservoirs
Controlled borehole permeability to seal out unwanted fluids
The fused borehole wall is structurally stable and provides sand control capability
Real-time formation analysis during drilling
Underbalanced drilling of laterals reduces formation damage and allows continued production during drilling
Drilling in thin reservoirs where hydraulic fracturing carries high risk
Drilling from small platforms where high cost rigs are not economical or technically feasible
Finding and precisely adding new intervals in depleted reservoirs
Bypassing near wellbore damage – beyond the range of conventional perforating
Eventual consideration for controlled fracturing.
Other Applications
We are aware of several other potential applications where bottomhole lasers will come handy. They include hydrates, wax, asphaltene, obstructions, and sand consolidation. Our development effort, however, is currently focusing on the two key applications.
