Development a new type of oil based drilling fluid with good temperature resistant

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2021
The complexity of reservoir conditions puts forward higher requirements for drilling fluid performance. The existing water-based drilling fluids (WBFDs) are difficult to meet the requirements at high temperature reservoirs.

Influence of additives on the friction and wear reduction of oil-based drilling fluid

Wear, 2019
In comparison to conventional vertical hole drilling, extended reach drilling wells with long horizontal section require higher driving torque due to the increased drag on the drill string, drill column, casing and other equipment. This has led to higher

Optimization of Reinjection Fluids of Oil-Based Drilling Cuttings

56th U.S. Rock Mechanics/Geomechanics Symposium, 2022
ABSTRACT: Oil-based drilling fluid will produce a large amount of oil-based drilling cuttings with complex composition and pollution factors. Cuttings reinjection technology, as an effective method to treat oilfield wastes, has gradually become a preferential choice for the treatment of oil-based drilling wastes in ...

Styrene butadiene resin/nano-SiO2 composite as a water-and-oil-dispersible plugging agent for oil-based drilling fluid

, 2020
In this paper, styrene butadiene resin/nano-SiO2 (SBR/SiO2) composite was synthesized by the continuous emulsion polymerization method, which was used as a plugging agent for oil-based drilling fluid (OBDF) to enhance plugging efficiency in shale ...

A New High-Temperature Oil-Based Drilling Fluid

Latin American and Caribbean Petroleum Engineering Conference, 1999
Abstract This paper presents the laboratory development and a field trial of a novel 100% oil base drilling fluid system. In response to the need for a competitive high temperature inhibitive system, lab testing found an oil soluble polymer that imparts high temperature high pressure fluid loss control in a mud system with stable ...

Evaluation of Claytone-ER as a novel rheological additive for enhancing oil-based drilling fluid performance under high-pressure high-temperature conditions

Clays and clay minerals
Conventional oil drilling fluids often fail under extreme (high-pressure high-temperature, HPHT) conditions, leading to wellbore instability and formation damage, causing substantial economic losses in the drilling industry. The objective of this study

Cement slurry contamination with oil-based drilling fluids

Journal of Petroleum Science and Engineering, 2017
Abstract Primary cementing constitutes the displacement of a cement slurry in an annular oil well. In the event of an unwanted mixture of drilling fluid and cement slurry during this operation, cement properties may be compromised. The aim of this study was to investigate the contamination in cement slurries caused by oil base drilling fluids ...

Oil-Based Drilling Fluids: Are they an Environmental Risk?

1987
The use of oil-based drilling fluids has been discouraged in hydrocarbon exploration and production in the marine environment but these drilling fluids are presently being used to a considerable degree in the Jnited Kingdom and Norwegian sectors of the North Sea.
