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...

Light annular mud cap drilling, downhole isolation valve help to drill fractured gas reservoir in Indonesia

An operator in Indonesia sought to drill on a gas field that lies on the western flank of the Central Palembang Sub-basin, in the South Sumatra Basin. South Sumatra is a Tertiary back-arc basin, approximately 500 km by 300 km. The pre-Tertiary rocks provide the lower reservoir portion of the gas field, while the upper portion of the reservoir is within porous Tertiary sediments of the Lower Talang Akar and Batu Raja formations. The Tertiary and pre-Tertiary reservoir rocks are enhanced by natural fractures...

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)...

Big data brings insights but also cybersecurity exposure

A critical theme that ran throughout our Critical Issues in Drilling and Completions Q&A’s in the last issue of DC was around data and how that’s taking center stage in the digital oilfield. That theme continues in this issue, where you can read about the latest evolution in intelligent coiled-tubing technologies (Page 42). Even in this hard-hit segment of the market – down by a whopping 41% from 2014 to 2015, then by an additional 39% in the year that followed – companies are looking toward data as the next step for advancing efficiency and cost effectiveness.

Drilling & Completion News

Maersk Drilling has been awarded a new contract with Petrogas E&P Netherlands for the high-efficiency jackup Maersk Resolute. The firm contract covers the drilling of the A8 and A9 wells in the A12 block of the Dutch Continental Shelf. The drilling of the two wells is estimated to have a duration of 75 days. Further, an option exists to extend the contract for up to five additional wells.

Perspectives: Thad Dunham, Flat Time Reduction: Drilling industry should look to industrial engineering to reshape operations, reduce waste

A Continued focus on cost reductions means drilling contractors are still looking for ways to reshape their operations to increase efficiency. Thad Dunham, President and Co-Founder of Flat Time Reduction, is helping companies to achieve such efficiency gains through an industrial engineering approach. “The principles of industrial engineering can work anywhere. The goal is to optimize processes and reduce waste,” Mr Dunham said. “If you look at everything as a process, whether it be an assembly line in a manufacturing plant or drilling a well, you can break it down into steps, get ideas from the folks doing the job, and you can improve it.”

HSE&T Corner: Involving employees in JSA development, making corrective actions visible increase buy-in to incident prevention programs

While the first and most important objective of an incident prevention program is to ensure employees get home safely, a strong program does more than protect people from harm. “They have the benefits of increased productivity, reduced costs and lower employee turnover,” Phil Molé, EHS Expert for Velocity EHS, said on 7 February at the 2017 IADC HSE&T Conference in Houston. “You improve employee morale and job satisfaction overall because you create the kind of environment employees like to be in.”
