Shale sweetspot technical service reduces costs

WellDog has released its Shale SweetSpotter service, which is the first commercial reservoir-evaluation analysis technology specific to unconventional oil and gas, following successful field trials with its industry partner in the Marcellus Shale, a press release stated. WellDog’s next-generation downhole technical service uses lasers and sophisticated detectors to identify the locations where hydrocarbons occur in shale formations, allowing producers to focus development efforts, reduce drilling costs, optimize production and reduce the number of hydraulic fracturing stages and associated water usage. The service uses WellDog’s Reservoir Raman System, which was originally developed to find sweet spots in coalbed methane developments. In 2014 the company began developing new shale-based applications for the technology. Shale SweetSpotter was developed with the target of doubling the number of producing fractures. This is accomplished by using the industry’s only downhole Raman spectrometer to directly identify locations of producible hydrocarbons across the formations.

Flowback service improves well productivity

Halliburton has released the CALIBR engineered flowback service, which applies advanced diagnostics and a collaborative workflow to continuously manage flowback operations to improve well productivity. It also helps maximize water recovery and reduce damage to fractures caused during drawdowns, a product announcement stated. Halliburton recently partnered with an operator in the Permian Basin to demonstrate the advantages of implementing an optimized flowback strategy to increase productivity. The well was drilled in what was believed to be marginal acreage, but by using CALIBR the operator was able to complete the well with the highest productivity index within its portfolio.

Hydraulic fracturing gets quiet

Liberty Oilfield Services has released its new Quiet Fleet technology, a press release stated. The Quiet Fleet utilizes patent-pending Liberty-developed sound reduction technology incorporated directly into fracturing equipment to dramatically reduce noise emissions during hydraulic fracturing operations. Noise levels are reduced by a factor of three compared to a conventional fracturing fleet, far more effective than costly sound walls. This noise reduction is achieved without any impact to operational performance or rigup time. The design of the Quiet Fleet also allowed the incorporation of a sophisticated threestage fire suppression system on each unit, which is not viable on a conventional fracturing fleet. The Quiet Fleet recently was deployed in the Denver-Julesburg Basin for Extraction Oil & Gas and completed 210 frack stages in the first 10 days of operation.

Virtual reality improves safety, productivity

Optech4D partnered with a manufacturer of high-speed rotating equipment (turbines, pumps and compressors) to develop a custom virtual reality product to support its training program, a press release stated. To ensure the safety of its employees and equipment, Optech4D’s client exercises the Lockout-Tagout (LOTO) system by which equipment is de-energized, locked and tagged so it cannot be started during maintenance or when highly explosive environments are present. The Optech4D Fully Immersive Training Simulator simulates the LOTO procedure training using virtual reality. By partnering with Oculus Rift, Optech4D developed a virtual world where the trainee can walk through the facility to check all critical equipment and verify that it is properly de-energized, tagged and locked out. In addition, Optech4D has leveraged augmented reality safety glasses and tablets and its SafeBeacon sensor technology to give operators in the field real-time assistance during LOTO.

Eccentric casing strings cut with single tool

A new technique developed by Energy Fishing & Rental Services (EFRS) was used to successfully cut totally eccentric 5-in., 7-in., 10¾-in. and 16-in. strings in a Gulf of Mexico well with a single cutting tool, a press release stated. The technique was developed in response to a problem faced by an operator during a plug-and-abandonment (P&A) operation. Because all four casing strings were cemented together, conventional multistep cutting using graduated-size cutting tools and knives was impossible. EFRS used a combination of specially fabricated cutter knives and an EFRS-designed procedure that used the correct combination of pump pressure and torque monitoring to cut all four totally eccentric inner strings using a cutter that typically could not have been used in this application. A job considered impossible was performed efficiently, with all strings cut and pulled. All four eccentric casing strings were cut using an EFRS 3½-in. outer diameter two-blade internal hydraulic casing cutter. The quick visualization, development and execution of specific procedures to complete an extremely difficult job has created a new option for effectively overcoming similar problems in P&A work.

Anticorrosion packaging eliminates rust claims

Cortec has released its EcoShield VpCI-226 Series Film, an easy-to-use packaging for corrosion protection, a product announcement stated. The film replaces the typical oils and desiccants used to protect packaged metal parts, not only guarding against corrosion but eliminating extra labor time and the hassle of removing greasy coatings. Metal parts protected in EcoShield VpCI-226 are ready to use immediately after unpacking. Once removed, the nontoxic film, which does not contain nitrites, phosphates or halogen-based materials, can simply be recycled. Metal parts packaged in the film are continuously protected from the corrosive effects of salt, excessive humidity, condensation, moisture, aggressive industrial atmospheres and dissimilar metal corrosion. Vapor-phase corrosion inhibitors in the film vaporize and condense on metal surfaces in the enclosed package, reaching every area of the part to protect the exterior as well as hard-to-reach interior surfaces. This provides complete product protection during storage and domestic or oversea shipments and virtually eliminates rust claims.

World’s first controlled pinpoint refrack

NCS Multistage has announced the successful refracturing of a 25-stage well that had originally been completed utilizing the company’s Multistage Unlimited coiled-tubing fracturing system and MultiCycle frack sleeves, which gave the operator the ability to manage stage-bystage formation access over the life of the well, a press release stated. After evaluating production, the operator wished to increase stimulated reservoir volume by placing additional proppant in all stages using a different fluid system and higher pump rates than used in the original completion. The refracturing began by closing all of the sleeves and verifying wellbore pressure integrity. Then, using the NCS Shift-Frac-Close sequence, all 25 stages were individually refractured. At each stage, the MultiCycle sleeve was opened for the fracture and then immediately closed at the end of pumping. When the stimulation was complete, the full-drift wellbore was again successfully pressure-tested, all sleeves were reopened and the well was turned over to production. The entire refracturing took about 36 operating hours, and wellbore pressure and formation access were controlled throughout the operation.
