Tullow Oil is cautiously reviving its search for new oil and gas resources in Africa and Latin America, its chief executive said.
But Paul McDade warned that the sector will need to walk a thin line to balance spending discipline with a desire to grow.
Deep spending cuts since 2014, asset disposals, the start-up of a major project in Ghana and a recovery in oil prices to more than $60 a barrel helped the African-focused company to boost cash generation sharply in 2017.
Still, uncertainty over how high oil prices can go amid surging US shale production means Tullow and the sector as a whole need to remain disciplined, CEO Paul McDade told Reuters.
"What will be critical for us and the industry is to ensure we maintain margins as oil prices pick up ... and not to get distracted by the higher oil prices."
The temptation is nevertheless big as some industry executives expect oil supplies to tighten by the end of the decade due to a drop in investment in recent years and as drilling costs remain extremely low.
Tullow plans to start drilling with the Maersk Venturer rig in Ghana in February to search for new oil and gas resources in the vicinity of its Tweneboa, Enyenra, Ntomme (TEN) and Jubilee offshore fields.
"We are carefully looking at whether we should add some rig capacity and we will only add that if we can maintain the financial strength of the company," Mr McDade said.
The company has used the weak price environment to acquire exploration licences in Ivory Coast, where it will begin seismic studies this year and which would be relatively quick and low-cost to develop if they prove to hold resources, he added.
Tullow said today it had also acquired six new licences offshore Peru and could start some exploration this year or in early 2019 if it obtained government approval.
"It is high-risk but very high-reward if it works," the company's chief executive said.
Despite the strongest start for oil prices in four years, global exploration spending is set to drop in 2018 for a fifth year in a row, masking a recovery in drilling activity as costs continue to fall.
In another sign of the sector's revival, Tullow expects it and its partners Total and CNOOC will approve the development of a new project in Uganda in the first half of 2018.
In today's trading update, Tullow said it generated around $500m of free cash flow in 2017, better than expectations, due to higher production and oil prices.
It expects its production to average 90,300 barrels of oil and gas equivalent per day (boed) in 2018, down from 94,700 boed in 2017, mainly due to several weeks of repairs planned on the Jubilee field.
The company reduced its debt burden by some $1.3 billion last year and refinanced a $2.5 billion credit facility in November.
