We provide unique business solutions to our clients. Our strengths are our people and a network of trusted partners with whom we design and deliver solutions for Oil & Gas and Industrial applications. Throughout the more than 40 year’s journey of our business, Oman Oil Industries Supplies & Services Co. LLC (OOISS) has maintained its focus firmly on the one aspect of business which is the source of our success: making sure we are appreciated by each customer for providing value-based solutions.

Over time, OOISS has become a leader in providing specialised goods and services to Oman’s Oil & Gas and affiliated industries. Our operations are supported by 50, 000 sqm facilities in Ghala Industrial and 80,000 sqm at the Nizwa industrial Estate, a transport fleet and over 150 committed members of staff.

A significant part of our business involves providing a broad range of chemical solutions to our clients. For example, we aid with the selection of optimal chemical technologies, establish arrangements for the reliable just in time delivery of the services and provide support with the accurate application of drilling, water treatment and process chemicals.

In collaboration with leading international design and technology companies, we provide mechanical and process equipment packages to the market. Wherever this is advantageous, fabrication and assembly are conducted in our sister company facility in Nizwa to increase the in-country value for Oman. OOISS strives to provide quality, value and technology-based solutions which our clients can depend upon.
