HSE&T Corner – Renewed focus on dropped object prevention needed as cost pressures, rig reactivations and personnel turnover amplify risks

By Mike Rice, Dropsafe According to industry body DROPS, dropped objects are among the top 10 causes of injury and fatality in oil and gas operations. Yet, dropped objects are also one of the only HSE areas without standardized legislation. This leaves individual project management teams solely responsible for ensuring the integrity of operational sites. This discrepancy has contributed to an increase, in real terms, of dropped object incidents in recent years. While oil and gas activity levels have declined with the fall in oil prices, the numbers of incidents have not decreased accordingly. However, the industry – including drilling contractors – has recently renewed its focus on drops prevention. For example, one major international drilling contractor recently issued a fleetwide ...

Mud pump cavitation: Routine inspections, maintenance can prevent ‘silent killer’ from reducing rig efficiency, equipment reliability

With pumps being run at max horsepower at today’s well sites, best practices can help contractors to avoid premature damage, extend consumables life By Adam Avey, Gardner Denver Cavitation is an undesirable condition that reduces pump efficiency and leads to excessive wear and damage to pump components. Factors that can contribute to cavitation, such as fluid velocity and pressure, can sometimes be attributed to an inadequate mud system design and/or the diminishing performance of the mud pump’s feed system. Other factors that contribute to cavitation include: • Improper sizing of charge pump; • Improper maintenance of charge pump impellers – worn impellers cause a reduction of fluid pressure; • Dirty or clogged charge pump feed and discharge lines; • Improper size ...

André Alonso Fernandes, Petrobras: Collaboration, sharing of lessons learned will be key to creating better MPD solutions

By Kelli Ainsworth Robinson, Associate Editor While studying mechanical engineering at the University of São Paulo in his Brazilian hometown, André Alonso Fernandes, currently Technical Advisor at Petrobras, became particularly fascinated with automation and how it can be used for optimization and process control. “That’s one of the things I really enjoy about MPD (managed pressure drilling), which is my current subject,” he said. By the time he graduated in 2001, he knew he wanted a job where he could see the results of his work. “I had an urge to be a field engineer so that I wouldn’t only be in the office but also would get to participate in real construction,” he said. However, this was December 2001 – ...

Editorial – Through international chapters/staff, IADC at work around the clock, around the world

As an international association, IADC takes seriously its mandate to provide representation for the drilling industry in all geographies in which its members operate. The issues and challenges we face vary vastly by region. As Vice President for IADC’s International Division, I work closely with our network of regional representatives to determine how the association can most effectively function as a strong proponent on behalf of member interests on a worldwide scale. With IADC headquarters based in the US, our regional representatives serve as the eyes and ears for the association globally. Working together with member companies and local and regional regulators and legislators, they determine how we can best use IADC’s resources to advocate for fair and transparent industry ...

Low-density, lightweight cement tested as alternative to reduce lost circulation, achieve desired top of cement in long horizontal wells

Locally sourced materials and supply chain optimization can help to keep lightweight cements cost-effective By Andy Jordan, Roderick Pernites and Lucas Albrighton, BJ Services Horizontal drilling awoke a new frontier in North America. This advanced drilling practice creates wells with mile-long horizontal sections, minimized hole diameters and maximized casing string diameters. Further, completion intensity has increased exponentially as longer horizontal wells are completed by fracturing with more stages and high-rate pumping. Casing programs have been optimized, often exposing weak formations to higher pressures for longer periods. The combination of exposed formations, longer laterals and smaller annuli poses challenges in achieving a successful cement job. These cementing operations require lighter and more stable slurries and in larger volumes. They also require cements ...

Independence Contract Drilling, Sidewinder to merge Independence Contract Drilling (ICD) and Sidewinder Drilling have announced their entry into a merger agreement in which ICD will acquire all outstanding equity interests in Sidewinder. The merger will combine two pad-optimal drilling fleets and operations focused on the Permian and other basins in Texas and its contiguous states. Upon closing of the transaction, ICD will more than double the size of its pad-optimal rig fleet to 34, following modest upgrades to five Sidewinder rigs.  The combined company’s board of directors will consist of four existing ICD board members, including ICD’s Chairman of the Board, Thomas R. Bates, as well as two members appointed by the controlling owners of Sidewinder. The combined company’s management ...

Drilling and Completion Tech Digest

Diamond Offshore launching new Blockchain Drilling Service across its rig fleet Diamond Offshore Drilling has launched its Blockchain Drilling service to drive efficiencies and enable oil and gas operators to reduce their total cost of ownership (TCO). The service provides an immutable platform for the optimization of well construction activities, including drilling-related services, material and the supply chain, both shore-based and offshore. Users can access and analyze performance from any web-accessible device for near real-time TCO management. The cloud-based platform is scalable, and the baseline system consists of five modules to drive efficiencies and eliminate waste: • The Supply Chain & Logistics Manager provides transparency, provenance and immutability across the entire supply chain; • The Well Planner displays actual vs ...

Pursuit of life-of-well integrity propels zonal isolation evolution

Increasingly harsh downhole conditions necessitate advances in cement spacers, packers and elastomers, boost use of barrier diagnostics By Kelli Ainsworth Robinson, Associate Editor, and Katie Mazerov, Contributing Editor Longer, deeper and hotter wells are upping the stakes for well integrity, driving an evolution in zonal isolation methods that give operators the assurance their completions endure for the life of the well. Research and development efforts for mechanical, fluid-activated and chemical solutions are ongoing to meet the rising challenges of these harsher downhole conditions that impact everything from elastomers to packers to cement. At the same time, the use of diagnostic tools to detect problems before they become problematic is growing.  Cement coverage is especially challenging in wells with low-pressure conditions or a ...

US Department of Interior Issues Proposed Draft of Unified Regional Boundaries In accordance with Executive Order 13781, the US Department of Interior (DOI) recently submitted reorganization proposals that include establishing 12 unified regional boundaries across all DOI bureaus. Currently, DOI has 10 bureaus and 49 regions, each operating with unique regional boundaries. This has inhibited the sharing of resources and discourages a shared frame of geographic reference, resulting in operational and administrative inefficiencies. The new draft identifies 12 common regions, which will enable better management of watersheds, wildlife corridors and trail systems. Indian reservations, national parks and other significant DOI land management units that cross watersheds and county lines were kept in the same region to promote efficiency. The 12 ...

IADC Supply Chain Committee releases Metrics, Scorecard The IADC Supply Chain Committee has developed standard supplier metrics and a scorecard. The supplier metrics were evaluated on impact to the supply chain process and the measurability by both suppliers and drilling contractors. These metrics are considered to provide the highest impact to the procurement process and considers safety, quality, delivery and service metrics. The IADC supplier standard metrics are service safety performance; revenue impact due to poor quality; non-conformances; on-time delivery; percentage late (of current orders); aged overdue open PO lines; invoice accuracy; and price variance. The standard metrics will be used to create a balanced scorecard that drillers can share with suppliers so they understand the driller’s priorities and expectations. ...
