RLG is involved primarily in the upstream segment of the oil and gas industry. It started its business in Malaysia and perforation is identified as the key product to spearhead its venture into the industry. Perforation is a highly specialized work which involves the use of explosive to punch holes through the casing of the well to connect it to the hydrocarbon reservoir. RLG is one of the pioneer Malaysian companies involved in such service.

RLG made their first overseas expansion into Vietnam in 2013. In late 2014, during the down turn of oil & gas market, RLG expanded its products & services beyond perforation and strategically identified well intervention related services due to depressing oil prices. RLG also acquired 100% stack in Amsito Oilwell Services (Malaysia) Sdn Bhd and 40% in Amsito Worldwide (BVI) Ltd in late 2015 to expand the business scope into the provision of slickline equipment and services.

2016 marked another milestone when RLG secured the Well Leak repair contract from PETRONAS and three additional contracts were awarded in 2017. More successes followed in 2017 when RLG is appointed as a panel contractor for the light weight well testing umbrella contract by PETRONAS and won the first mini bid in August 2017. In September 2017, RLG was awarded the well leak repair contract in Mauritania, adding another entry in overseas ventures.
