Lightweight frac plug reduces post-frac intervention time
Baker Hughes, a GE company (BHGE), has released its MILLITE lightweight frac plug, which “mills out more smoothly and cleans up better than any other conventional frac plug on the market, cutting costs and helping customers achieve first oil faster,” according to a company press release. Constructed completely of an engineered alloy material, the MILLITE plug does not contain any heavy metal or ceramic parts. The plug’s wear- and preset-resistant design virtually eliminates preset risks, enabling safe run-in rates in excess of 600 ft/min. A field-ready wireline adapter kit simplifies assembly, and the plug’s friction-slip anchoring system and packing element keep it firmly anchored in the casing at pressures up to 10,000 psi. The MILLITE plug mills more rapidly and more easily with less torque, helping to improve motor life and reduce drilling costs. With a specific gravity of 1.8, the plug’s fine debris can float up and out of the well without the aid of additional cleaning sweeps or costly chemicals. At under 13 in. long, its compact design also contributes to a lower overall volume of debris per plug compared to standard plugs. bhge.com
Improved data-capturing system increases efficiency, reduces costs
Halliburton Co. has released its Cerebro in-bit sensor package, a new technology that obtains performance data directly from the drillbit and analyzes those data to optimize cutter engagement, reduce uncertainty and increase drilling efficiency, according to a press release. Cerebro provides an unprecedented view into an entire run by continuously capturing downhole vibration and motion data. This information helps operators pinpoint where bit damage occurred and when optimal performance is not achieved due to inconsistent design or operating parameters. The system identifies several common drillbit factors, including lateral and axial vibration, torsional resistance, whirl and stick/slip, which can negatively impact drilling speed and reliability. On a recent set of runs in the U.S. Midcontinent, Cerebro acquired information that allowed the operator to utilize a more aggressive cutting structure to increase drilling efficiency and reduce well time. These data also showed that higher drilling speeds could be used in softer sections of the well without vibration limitations. halliburton.com
New offering determines the effect of frac hits by using pressure-based technology
Reveal Energy Services has released its FracEYE frac hit analysis service, which is designed to expand the industry’s knowledge base about the critical issue of parent well-child well communication, a press release stated. With ongoing infill development, frac hits from the pressure communication between wells can cause significant production decreases in parent wells. Child wells also can underperform. The goal of the Reveal Energy Services’ R&D team was to clearly define the effect of frac hits and allow operators to make timely adjustments to their completion designs. The foundation of the FracEYE service is the company’s pressure based technology. The service categorizes the type and severity of interwell communication by measuring the pressure response from a parent well as hydraulic fracturing proceeds normally in child wells. A team of company geoscientists and completion engineers uses the pressure-response timing and geomechanics to classify the observed response into one of four categories: direct fluid transport, fluid migration, undrained compression and no signal. reveal-energy.com

Smart alerting system for drilling operations helps eliminate alert overload
Petrolink has released its Manage By Exception (MBE) system, a software solution designed to help drillers manage the high volume of alerts generated during drilling by prioritizing them, thus enabling drillers to raise only the priority ones to exactly the right person at the right time, according to a company press release. Based on user-defined exceptions, MBE is a productivity enhancing system that puts the user in control of which alerts to display, thereby eliminating alert overload. MBE allows users to identify which wells and wellbores to monitor and enables them to send the corresponding alerts to selected personnel on the system. The system identifies initial issues before they become a problem, allowing operators to correct events in real time and ensure the integrity of their equipment. Users also have the flexibility to adjust rule or notification behaviors to adapt the system to a variety of critical real-time situations and well/wellbore scenarios. The system can monitor multiple workflows remotely across a fleet of rigs or implement companywide drilling activities and best practices on every active well. In addition to the onscreen notifications, the MBE system can send messages via text and email, allowing key personnel to continue their routines outside of the office while they are away from the computer. petrolink.com
Online ROVs marketplace flags opportunities
ROVHUB has launched the first online marketplace for ROVs, the company said in January. Founder David Gault said he developed ROVHUB after seeing ROVs lying idle during the 2014 oil and gas downturn. “The oil and gas market is picking up, but there is still spare ROV capacity,” he said. “ROVHUB can flag up alternative opportunities for owners outside their core regions and in other sectors such as renewables and aquaculture.” Gault added that the service makes other industries aware of oil- and gas-focused ROVs that might be available for their work. ROVHUB took two years to develop and boasts thousands of ROVs and hundreds of ROV companies in its database. Gault considers it a component of a digital trend in the marine and offshore industries. “Adoption of digital technologies is gathering pace in the oil and gas industry,” he said. “It’s not just about cost-cutting, it’s also about automating manual processes to free up resources that can be used more effectively elsewhere, and it’s creating opportunities by doing things differently.” rovhub.com
New liner top packer can withstand high differential pressures
National Oilwell Varco (NOV) has released its new MSF liner top packer for hydraulic multistage fracturing to its portfolio of completion tools and technologies. Rated to 10,000-psi differential pressure and a maximum operational temperature of 300 F, the new liner top packer is qualified to the rigorous standards of American Petroleum Institute 14310 V3. The system is designed specifically for the challenges of horizontal hydraulic multistage fracturing completions, and it can withstand high differential pressures and heavy tubing loads during stimulation. The slips, designed with nearly fully circumferential contact with the casing, ensure that the system will perform under stimulation pressures even in high-yield grades of casing. In addition, a one-piece sealing element helps to avoid swabbing and enables the higher circulation rates required to maintain hole cleanliness during deployment of the liner. nov.com
Software estimates geomechanical logs, pore pressure, stresses and natural fracture
FracGeo has released its software module DrillPredictor, which is a cloud- and subscription-based web service designed to put completion optimization in the hands of any unconventional reservoir operator, a press release stated. The technology uses commonly available surface drilling data from any contractor to provide the information needed to adapt any frac treatment to the variable subsurface geologic and geomechanical conditions. DrillPredictor uses FracGeo’s Corrected Mechanical Specific Energy (CMSE), which accounts for frictional losses along the wellbore for any type of drilling equipment including rotary steerable systems and mud motors. FracGeo’s CMSE is used to compute unique products, such as pore pressure, stresses, natural fractures and geomechanical logs along the wellbore. These logs are then used immediately after drilling the well to provide multiple completion optimization strategies that are quantified with an estimated cluster efficiency, followed by the propped fracture geometry and the resulting depletion using FracGeo’s advanced and fast frac design and reservoir simulation technologies. These estimations are validated with fiber optics, microseismic moment tensor inversions and production logs. fracgeo.com
Scientists create new oil-resistant filter technology
Crude oil is sticky stuff and often clogs filter membranes and other equipment used in the oil and gas industry. Scientists at the U.S. Department of Energy’s Argonne National Laboratory have developed a novel, patent-pending approach that will prolong the lifetime of key industrial equipment. The new invention consists of water-loving, oil-repelling thin film coatings on the surface of filter membranes. These metal oxide coatings grab onto any loose water molecules while resisting oil. Fouled membranes can be a costly hassle for the oil and gas industry. For instance, replacing clogged filters during hydraulic fracturing often requires shutting down equipment. Oil-resistant membranes could significantly reduce the need for both filter replacement and downtime. Also, Argonne’s atomic layer deposition process keeps membranes from clogging during hydraulic fracturing to better filter the water passing through them, allowing operators to reuse water. This could be a direct replacement for filter units in use today. The method also could help in oil spill cleanup efforts. Pipe and container surfaces treated with the oxides could just be rinsed clean. anl.gov
New AI technology to accelerate projects
BP Ventures has invested $5 million in Belmont Technology’s Series A financing to further bolster BP’s artificial intelligence (AI) and digital capabilities in its upstream business, according to a company press release. Belmont, a Houston technology startup, has developed a cloud-based geoscience platform using AI that has a string of unique capabilities, including specially designed “knowledge-graphs.” BP experts feed the platform geology, geophysics, reservoir and historic project information. Then the platform intuitively links that information together, identifying new connections and workflows and creating a robust knowledge-graph of BP’s subsurface assets. Much like data searches available in the consumer domain, BP experts can then interrogate the data, asking the powerful knowledge-graph specific questions in natural language. The technology then uses AI neural networks to interpret results and perform rapid simulations. Aimed at accelerating project life cycles, from exploration to reservoir modeling, the technology is targeting a 90% time reduction in data collection, interpretation and simulation, the release stated. bp.com
