Golden, CO - Using a laser to drill through rock has beendiscussed in the oil and gas industry since the developmentof the high-power laser. It was attempted to develop a CO2-based laser drill in the 1960s, but concluded thatthe technology is premature due to its size and complexity.

Ramona Graves of the Colorado School of Mines has demonstrated the potential oflaser drilling by destroying a rock with advanced chemical laser, andcharacterized the ability of a high-power diode laser to drill through rock.There is still substantial gaps in the technology that prevents commercialdevelopment.

The innovation opened up the prospect of commercializing laser drilling was the introduction of a10kW fiber laser by IPG Photonics. With the assistance of CSM, itstarted developing a laser drilling process capable of creating acommercial-grade borehole, with the supporting technology to field a laserdrilling system.

The goal of this work was to demonstrate speeds for drilling through ultra-hardcrystalline rock compared to a conventional drilling system, which in turnreduces the cost of drilling geothermal wells. The Department of Energy's AdvancedResearch Projects Agency, Energy (ARPA-E) and CSM, we have demonstrated adrilling process with a faster rate of penetration and substantial decrease inthe weight on bit that ultimately leads to a longer bit lifetime.

The transaction contains all intellectual property including trademarks, know-how, patents, and patent applications of FiLaser. The transaction, which is subject to customary closing conditions, is expected to close in March 2014.

Patrick Newton, analyst from Stifel-Nicolaus, said via BlueMatrix: “We view Rofin-Sinar’s acquisition as bolstering the company’s position in strengthened glass/sapphire cutting, which we see as one of the most exciting growth opportunities for the laser industry (Rofin, Coherent, TRUMPF, IPG Photonics and others are all targeting this market) over the next several years.”

Günther Braun, president and CEO of Rofin, said: “We are proud that FiLaser selected Rofin to market this technology. With the signing of the asset purchase agreement, we are able to upgrade and complement our comprehensive ultra-short pulse laser offering with a specialized unique technology for the cutting of brittle materials, like glass and sapphire. The commercialization of this technology is an important step for the industry in improving the cutting performance of these materials and subsequently the wider use of laser technology. We look forward to further developing and applying this technology to a broader range of materials.”

“Rofin is an ideal technology commercialization vector, bringing scale, experience and integration prowess to bear on the problems of technology development and dissemination,” said Jeffrey Albelo, CEO and chairman of FiLaser. “We believe the nexus of FiLaser innovation and Rofin expertise in systems and lasers to be a winning combination. It enables optimal capture in the broadest market cross-section and greatly improves the adoption profile. We expect great things and we are excited to have our technology become a part of the Rofin technology portfolio.”

Rofin-Sinar Technologies focuses on developing key innovative technologies and advanced production methods for a wide variety of industrial applications based on a broad scope of technologies. The product portfolio ranges from single laser-beam sources to highly complex systems, covering all of the key laser technologies such as CO2 lasers, fiber lasers, solid-state lasers and diode lasers.

FiLaser has developed advanced laser process technology used for precision cutting and drilling of brittle materials including glass, sapphire, and semiconductor substrates. Its applications are found in the touch panel, LCD, cell phone display, LED, and semiconductor markets.

Drill bitinnovator exploring 3D laser manufacturing systems

Houston, TX - BlueFireEquipment Corp., a designer and manufacturer of proprietary drillingtechnologies for the exploration and production of oil and gas in the US, hasformed a 3D or additive manufacturing initiative for theproduction of its proprietary polycrystalline diamond cutter (PDC) drill bits.

BlueFire's development team is exploring theapplication of 3D methods for producing the company's drill bits and iscurrently working with a Texas-based 3D scanning company to create a digitizedmodel of the proprietary PDC drill bit for 3D integration. Using the 3Dcomputer-aided design (CAD) software, the team is developing ways to integratethe company’s technology with game-changing 3D technology. The team is also working tobecome a frontrunner in the field of down-hole drilling tools employingadditive manufacturing systems.

Additive manufacturing, or 3D printing, is a process by whichthree-dimensional objects in a diversity of shapes are manufactured by addingmaterial using digital models. Metallic, plastic, ceramic, or compositematerials can be employed using this process, which involves building therequired object by adding successive layers of material to achieve the desiredshape.

3D printing uses a variety of different types of technologies. Stereolithography (SLA) focuses a beam ofultraviolet light onto a vat of liquid photocurable resin, drawing out the 3Dmodel one layer at a time. Fused deposition modeling (FDM) producesan object by extruding a stream of melted material to form stacked layers.Selective laser sintering (SLS) uses a laser to fuse powdered materials layerby layer to form the object.
