Open-hole, multizone completions drive development of single-trip sand control technologies

As operators continue to drill deeper wells in more remote offshore locations, the traditional wait-and-see approach to sand control is no longer an option in many cases. Operators have recognized that a proactive strategy is needed, and many are actually installing sand control equipment during the well’s initial completion, rather than waiting to do so only when sand production becomes a problem...

New digital age may disrupt traditional business models

By Linda Hsieh, Managing Editor The length and severity of this downturn have triggered a lot of discussion around the industry’s business model. Much of the discussion has centered around revising the traditional dayrate model to incentivize performance, but do such bonus schemes go far enough? The drilling industry is at the cusp of an inflection point in its digital revolution. From automation to robotics, from data analytics to artificial intelligence (AI) – every day new technologies are pushing the industry ever closer toward changes that could significantly disrupt the business model as we know it. Numerous other industries have already undergone such disruptions, typically with new-to-industry “disruptor” companies coming out on top. “Uber is the world’s largest taxi company, ...

Small signs hint at possible recovery in still-sluggish North Sea

Although the North Sea drilling market is still quite a ways from what one might call healthy, small signs of recovery are starting to sprout. Several operators, for example, have publicly touted significant reductions in their breakeven costs for offshore projects – from Maersk Oil’s $40-45 range for pre-FID projects to Statoil’s $27 for pre-FID Norwegian Shelf projects...

Perspectives: Harris Reynolds, Diamond Offshore Drilling: Boom or bust, offshore industry must focus on innovations to drive down costs

In an industry downturn, especially one as severe as the one currently plaguing the oil and gas business, it can be instinctive for companies to postpone investments in technical innovations. But Harris Reynolds, Director of R&D at Diamond Offshore Drilling, believes that would be a short-sighted approach. “We have to bring the cost of exploration and production down radically,” said Mr Reynolds, who also serves as Chairman of the IADC Future Technology Subcommittee. “There has to be a paradigm shift to get costs down for offshore.”...

IADC South Central Asia Chapter hosts safety workshop On 25 March, the IADC South Central Asia Chapter hosted a Hand & Finger Safety Workshop in Agartala, India. The workshop was organized to bring awareness to hand and finger injuries. According to IADC Incident Statistics Program data, such injuries comprise more than 43% of all recordable incidents on drilling rigs. Those who attended the conference were divided into nine groups, and each was given a safety case to determine key preventive measures. From left are Suresh Mehra, ED Chief HSE, ONGC; Mike DuBose, IADC VP of International Development; V.P. Mahawar, Director Onshore, ONGC; S.C. Soni, ED Asset Manager, ONGC Agartala.

Casing-integrated, surface-activated well control tool supplements BOP in uncontrolled blowout scenarios

Prototype of well restriction tool has been designed and tested under static conditions; additional analyses in dynamic conditions still needed Zach Owens, Brian Smyth, Nicoli Ames, John Pye, and Brun Hilbert, Exponent; Bob Brooks, RM Taber; Hector Mendez, Shell International Exploration and Production In 2014, Royal Dutch Shell engaged Exponent to develop a prototype of a surface-activated, casing-integrated, flow-restriction tool capable of arresting flow during an uncontrolled blowout. This well restriction tool (WRT) is similar in function to a subsurface safety valve (SSSV) but is designed to be an integral component of a 9 5/8-in. casing string. Unlike an SSSV, the WRT is intended for use during drilling and can be installed deep in the well near the end of ...

Study targets potential for gas loading in drilling fluids to improve influx detection, management

Well control is a continuous and top priority for maintaining safe and efficient drilling operations. Particularly during deepwater and HPHT drilling, potential gas kick situations can be more difficult to detect topside due to the expansion potential of reservoir influxes. To detect gas influxes, knowledge of the interaction between natural gas and the drilling fluid at relevant process conditions is critical...

No room for failure in RSS performance as cost pressures persist

Today’s rotary steerable systems (RSS) are being developed with one primary goal: delivering high-quality wellbores at low cost. Some service companies are reducing costs by developing more durable tools that can drill for longer in harsh environments, while others are focused on reducing the cost of the tool itself by eliminating non-essential functions...
