Well 01 and Well 02 are part of the phase 1-6 project that involved the development of six wells with the potential to deliver an additional 70% production increase to the LNG export market. The sand face for both wells was drilled with 0.72psi/ft pseudo oil-based mud (POBM). After the initial well clean-up, both wells produced sub-optimally (~20% of estimated potential) with relatively high drawdown (ranging from 500psi – 1000psi). This low production was suspected to be because of downhole (screen and formation) impairment or partial opening of the formation isolation valves (FIV).
A restoration team was set up with a responsibility to proffer a robust well intervention execution plan and select the most potent barite dissolver. Nine stimulation chemicals were tested and based on the team criteria, CHEM-001 and CHEM-002 were selected as main-treatment and pre-flush chemicals, respectively.
The downhole and surface conditions that exist in deep high-pressure wells pose many challenges to the coiled tubing industry as it strives to provide safe and reliable access to the wells. This paper highlights a case history of successfully snubbing coiled tubing (CT) into two deep (about 14,000ft+) live wells (Well 01 and Well 02) with a high surface pressure (7000psi+) and temperature (80 – 100°C) to stimulate both wells. The success criteria post stimulation was targeted at 75% of the potential production value. However, post treatment results show that cumulative gas production increased by 375% (with about 200psi) with a potential to increase up to 400%.
This paper details the entire operations during the CT well intervention, the planning, design, and technical analysis which led to the selection of a CT with 130,000psi yield strength on a 125K CT injector system, force simulations, and laboratory tests on CT with stimulation chemicals which led to a successful stimulation campaign. The paper also covers the initial planned versus actual operations and the lessons learned leading to on-the-spot optimization plans that resulted in a highly successful intervention operation.
Echoing a common complaint in the impoverished swampland that produces most of Nigeria’s oil, the protesters said they were not benefiting from the region’s oil wealth and wanted an end to the oil pollution that has ruined much of the land. Opponents of the Keystone XL pipeline vowed on 10 August to block construction of the controversial project if Nebraska regulators approve the proposed route later this year.
Recently, Nigeria's Department of Petroleum Resources issued guidelines in furtherance of the objectives of the Flare Gas (Prevention of Waste and Pollution) Regulations, 2018. Nigerian militants threatened on 17 January to attack offshore oil facilities within days, raising fears of a repeat of a 2016 wave of violence that helped push Africa’s biggest economy into recession. Is Crude Oil Killing Children in Nigeria? A recent report by a group of scientists at the University of St. Gallen in Switzerland found that children born within 10 km of an oil spill were twice as likely to die in their first month. The Nigerian Petroleum Industry Bill possibly ranks as No. 1 by a wide margin among the bills that have spent the most time with the legislature.
Anadarko Petroleum wants a fleet of at least six vehicles with armor heavy enough to stop AK-47 bullets at its natural-gas project in Mozambique. And it needs them soon. By examining two very different security-risk environments, this paper will illustrate how easily security-related human-rights risks can go unnoticed unless care is taken early in the risk-management process. Oil production at Libya’s Sharara field, the country’s largest, was resuming on 6 September after a valve was reopened on a pipeline shut by an armed group for more than 2 weeks, Libyan oil industry sources said. A third Damen security vessel will be deployed to provide security and other support services to the international offshore oil companies active off the coast of Nigeria in the Gulf of Guinea, in cooperation with the Nigerian Navy.
The Nigerian National Petroleum Corporation announced a three-point smart strategy aimed at ending gas flaring in Nigeria’s oil and gas industry in 2 years. Climate Change has brought the oil industry face-to-face with the enormous challenge of providing the world with a source of efficient and reliable energy while at the same time ensuring that CO2 emissions are mitigated.
Lloyds Register Senior Flow Assurance Engineer Oche Ameh explains what flow assurance is and the importance of this field in oil and gas extraction.

America’s hottest oil patch is producing so much natural gas that, by the end of last year, producers were burning off more than enough of the fuel to meet residential demand across the whole of Texas. While much progress has been made to reduce flaring, associated gas continues to be flared at thousands of oil production sites around the world.

Climate Change has brought the oil industry face-to-face with the enormous challenge of providing the world with a source of efficient and reliable energy while at the same time ensuring that CO2 emissions are mitigated. Honeywell announced that its Callidus Technologies business began operation of China's only facility capable of testing flare emissions for volatile organic compounds.
Africa (Sub-Sahara) San Leon Energy reported encouraging performance from its OML 18 field in Nigeria. Reperforation of an oil well increased gross field production to approximately 61,000 B/D before output was temporarily scaled back to 53,000 B/D for a shut-in, upgrade, and workover of the well. A number of other field wells will be reperforated in coming months, the company said. San Leon holds a 9.72% interest in the field, which is operated by Eroton (35%). Nigerian National Petroleum Corp. holds the remaining stake. FAR said that drilling has begun on the SNE-5 appraisal well offshore Senegal. The well and the following SNE-6 well will evaluate the upper SNE reservoir units' connectivity and deliverability by oil flow testing that will include interference tests.
The SPE Board of Directors meeting was recently held in Cairo. My intent is to share important information with our members after each meeting. As SPE, and the industry, emerge from the downturn, one of the Board’s most important topics of discussion was financial. The New SPE International App allows you access to SPE anytime, anywhere.
