Coiled-tubing cementing operation on HPHT well uses MPD technique to lower costs, ensure integrity

The number of exploration wells drilled in high-pressure, high-temperature (HPHT) environments keeps growing, spurred by the ongoing search for new oil and gas reserves. Per the Norwegian Standards Organization (NORSOK), an HPHT well has a wellhead shut-in pressure exceeding 69 MPa (10,000 psi) and an ambient temperature greater than 150°C (302°F)...

Evolution of intelligent coiled-tubing technologies drives need for better sensors, data interpretation tools to aid real-time decision-making

Coiled-tubing interventions, like everything else in the upstream sector, have taken a hit since oil prices tumbled in 2014. In fact, the coiled-tubing industry declined by 41% from 2014 to 2015 and by an additional 39% from 2015 to year-end 2016, according to data from Spears and Associates...

Influx management envelope deployed during planning phase for 3 sections of deepwater MPD well

The MPD Operations Matrix was introduced in 2007 to serve as an operational guide for drilling MPD sections. The intent of the matrix is to balance operational, well and equipment limitations with “acceptable” influx volumes. The operations matrix has become the cornerstone of MPD projects worldwide and is a mandatory component of planned MPD wells in the US Gulf of Mexico...

UT Austin-based drilling automation consortium builds data visualization templates, develops data-driven top drive monitoring techniques

Although automated drilling has been a popular discussion topic among drilling engineers for much of the past decade, practical solutions have been slow to emerge. Since its launch in May 2015, the University of Texas-based Rig Automation and Performance Improvement in Drilling (RAPID) consortium has worked to speed the pace of automated drilling innovations by delivering pragmatic and immediately applicable solutions to some of the drilling industry’s most pressing issues...

New drill stem rotary shoulder connection incorporates innovative single start shark thread shape

For the past century, the oil and gas industry has been pushing the limits of the existing drilling envelope to reach deeper, more remote hydrocarbon reservoirs. The evolution of drilling programs has driven drill string manufacturers to engineer new drill pipe solutions to safely develop the most challenging horizontal and extended-reach drilling (ERD) well profiles.

Extended life, quicker make-up and gas tightness among key innovation areas as operators seek larger tubulars, lower costs of ownership

In a market where operators and drilling contractors alike are analyzing every nickel and dime in their operations, drill pipe manufacturers must ensure tubular technologies are providing the required performance at an accessible cost. “What we’re doing right now is helping companies to reduce their cost of ownership,” said Guillaume Plessis, Director of Global Marketing for Grant Prideco, a National Oilwell Varco (NOV) company. “We will still see optimization of the product, but we also want to make it a very affordable possibility.”

Experimental setup at Texas A&M Dual Gradient Drilling Lab aims to study riser gas migration in controlled mud level drilling system

Growing demand for energy is pushing operators to drill in ever-increasing ocean depths. Deepwater offshore reservoirs often exist where the required pressure from the drilling mud for well control is very near the pressure at which overlying layers can break down, resulting in loss of circulation of drilling mud to thief zones, inviting dangerous kicks of high-pressure gas and oil. Such narrow drilling pressure windows leave razor-thin margins for error...
