Considering its complexity, oil and gas industry is not as slow to innovate as many think

screen-shot-2017-03-16-at-4-22-04-am

The drilling industry has long been labeled as being slow to embrace new technologies and innovation. However, that may not be an accurate characterization of the industry, Ekaterina Minyaeva, Drilling Automation, Subsurface and Wells Consultant at OTM Consulting, said in a presentation at the 2017 SPE DSATS/IADC ART symposium on 13 March in The Hague, The Netherlands...

Data analysis, visualization project develops drilling engineers of the future

screen-shot-2017-03-16-at-4-35-31-am

As big data and automation play increasingly significant roles in drilling operations, the skill sets required of drilling engineers of the future are also changing. For one, they will need to be adept at data analysis, Dr Eric van Oort, Consortium Director for the RAPID program at UT’s Cockrell School of Engineering, said at the 2017 SPE/IADC Drilling Conference in The Hague, The Netherlands...

New interface protocols drive communication efficiencies between subsea control modules and subsea sensors

default-img-featured-subsea

The Subsea Instrumentation Interface Standardization (SIIS) network released its Recommended Practice and Standard Text for inclusion in API17F, the American Petroleum Institute’s (API) Standard for Subsea Production Control Systems. The three instrument interface protocols, covering analogue devices, digital serial devices and Ethernet TCP/ IP devices, will help improve subsea reliability by standardizing communications between subsea control modules and subsea sensors. SIIS was established in 2003 with a remit to create an open standard for the benefit of the oil and gas industry as a whole. The new Recommended Practice and text for an API Standard is expected to improve communication between members and strengthen the subsea control system ‘community’, reduce project lead and delivery times, remove repeated one-time engineering costs, ...

Diamond Offshore develops Floating Factory drillship concept using lean manufacturing principles

Diamond Offshore developed the Floating Factory concept to eliminate waste and reduce costs for offshore drilling, James Hebert, Director of Operations and Technical Support, said on 14 March at the 2017 SPE/IADC Drilling Conference. The design includes a dual mud pit system and 50% more deck space compared with typical sixth-generation rigs.

By Kelli Ainsworth, Associate Editor  As part of its efforts to lower offshore drilling costs, Diamond Offshore has developed the Floating Factory drillship concept. The rig features a Huisman drill tower, a dual mud pit system and 50% more rig space than typical sixth-generation drillships, James Hebert, Director of Operations and Technical Support for Diamond Offshore, said. “We all agree that we need to reduce well delivery times and improve the economics to try to drive the costs of offshore development,” Mr Hebert said in a presentation on 14 March at the SPE/IADC Drilling Conference The Hague, The Netherlands. “We’re trying to take a step back from how we previously looked at rig designs and trying to see what we ...

New control software aims to optimize water treatment processes

Drinking-Water2

Water Planet has deployed its new IntelliFlux control software at California’s first merchant facility designed to treat oil and gas produced water for beneficial reuse. Operated by Sweetwater Tech Resources (STR), this regional water treatment facility gives local oil and gas producers a reliable, economic and sustainable option for converting billions of gallons of produced water annually into clean water streams available for beneficial reuse. It is located in Wasco, a town centrally located around multiple active oil fields surrounding Bakersfield. Because the wastewater can be treated for reuse, oil producers have a cost-competitive option to trucking it to third-party disposal wells. The project is expected to yield significant environmental benefits by reducing the amount of water disposed, as well ...

New drill bit adjusts to downhole conditions for smoother, faster drilling

baker-hughes-drill-bit

Baker Hughes’ newly released TerrAdapt adaptive drill bit is expected to deliver dramatic improvements in drilling economics by using automation to mitigate downhole dysfunctions that cause inefficient drilling and costly tool failures. With the industry’s first self-adjusting depth-of-cut (DOC) control elements, the TerrAdapt bit automatically changes its aggressiveness based on the formation through which it is drilling to mitigate vibrations, stick-slip and impact loading...

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

Dual Gradient

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

The lower completion consists of a float shoe with a flat-bladed nose, alternating joints of pre-perforated, frangible disk plug, and a 7-in. x 9 5/8-in. liner top packer.

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...
