This study examines the effectiveness of sodium erythorbate, potassium formate, and
polyethylene glycol for the formulation of high-performance water-based drilling fluids. High …

In this study, three types of polypropylene glycols (PPGs) were added in basic mud as
additives. Different chemicals were added to adjust the pH value of mud. PPGs were found …

Wellbore instability due to shale hydration and dispersion is always a challenge in oil and
gas drilling engineering. Hydroxyl-terminated polyamidoamine (PAMAM-OH) dendrimers …

Slim-hole drilling has been widely developed in oil and gas industry. Frequent kicks,
circulation loss, borehole wall destabilization, difficulty in cutting carrying, and stuck pipes …

Hydrated shale formations often lead to severe drilling problems and may lead to wellbore
instability. These instabilities can result in issues such as bit balling, borehole collapse …

The use of water-based mud (WBM) in drilling applications under extreme reservoir
temperatures has been increasing rapidly in the drilling industry over the past few years. It is …

根据不同井温需求, 开发了2 种浊点温度的钻井液用聚醚多元醇页岩抑制剂BDSC-300L-A,
BDSC-300L-B, 其浊点(3%) 分别为55, 70℃, 页岩线性膨胀率降低率大于50%, 且不起泡 …

The negative environmental impacts of drilling muds, particularly oil-based muds, are a
cause for concern to regulators and governments worldwide. As a result, rules regarding the …

The negative impacts of drilling fluids, most especially oil-based muds, on the environment
are a source of concern to regulators and governments all over the world. Consequently …
