The Legal 500 EMEA, 2021

The team at CMS, led by Martika Jonk, has been both very professional and very personable. Their willingness to engage with our business and issues at either a detailed or superficial level, depending upon what we needed was a refreshing change from those law firms who believe that they know best when it comes to how much effort needs to be put into every question asked of them.

En­ergy Trans­ition: The evolving role of oil & gas com­pan­ies in a net-zero...
After an ex­traordin­ary year of health and eco­nom­ic chal­lenges, the glob­al oil and gas sec­tor has an es­sen­tial role to play in the eco­nom­ic re­cov­ery. The same could how­ever be said of any eco­nom­ic re­cov­ery and ex­pan­sion over the past 100 years – dur­ing this time oil and gas com­pan­ies have provided most of the primary en­ergy that has fuelled huge eco­nom­ic growth. But this time does look dif­fer­ent. The oil and gas sec­tor will power eco­nom­ic re­cov­ery not just through oil and gas ex­plor­a­tion and pro­duc­tion, but also (and per­haps counter-in­tu­it­ively to some) through fa­cil­it­at­ing the trans­ition to a lower-car­bon eco­nomy and even­tu­ally a net zero fu­ture. This re­port presents a wide-ran­ging re­view of the role of oil and gas com­pan­ies in that fu­ture.

Oil and Gas Dis­putes Sur­vey: Man­aging dis­putes risk – the in-house per­spect­ive
The CMS Oil and Gas Dis­putes Sur­vey ex­amined the key drivers of dis­putes and dis­pute man­age­ment in the oil and gas in­dustry, and how sec­tor par­ti­cipants are mov­ing to­wards new ap­proaches to min­im­ise con­flicts and dis­putes. Based on more than 50 re­sponses from seni­or leg­al man­agers and seni­or in-house coun­sel in the oil and gas in­dustry across Europe, the Middle East, Asia Pa­cific, Africa and Lat­in Amer­ica, it provides in­ter­est­ing in­sights in­to how dis­putes arise and are man­aged around the globe.Even be­fore the on­set of the COV­ID-19 pan­dem­ic, the oil and gas in­dustry was fa­cing con­sid­er­able chal­lenges, not least a pro­longed peri­od of re­l­at­ively low oil prices and a glob­al fo­cus on lower­ing car­bon emis­sions and “green” en­ergy.Com­pared with the heights of 2008, pri­or to the glob­al fin­an­cial crisis, when in­ter­na­tion­al oil prices peaked at over US$140 a bar­rel, the US$55 bar­rel price for Brent Crude in late Janu­ary 2021 still looked re­l­at­ively low, des­pite the re­cent par­tial re­cov­ery. Those weak prices con­tin­ue to place con­sid­er­able pres­sures on in­dustry play­ers that are now of­ten op­er­at­ing on his­tor­ic­ally low mar­gins of prof­it­ab­il­ity.It was not al­ways this way. As ver­tic­ally in­teg­rated gi­ants, oil and gas ma­jors were tra­di­tion­ally con­sidered well able to ab­sorb down­sides with­in a broad port­fo­lio of rev­en­ues and part­ner­ships, but today many in­dustry play­ers no longer have that lux­ury. A num­ber of geo­graph­ic mar­kets that were pre­vi­ously dom­in­ated by a few large up­stream oil com­pan­ies have transitioned through di­vest­ments to own­er­ship by a lar­ger group of smal­ler in­de­pend­ent play­ers with more fo­cused port­fo­li­os and a range of fin­an­cial mod­els. With more op­er­at­ors and par­ti­cipants in many oil and gas geo­graph­ic mar­kets, it seems likely that the op­por­tun­it­ies for dis­putes are in­creas­ing. CMS Oil and Gas Dis­putes Sur­vey in­dic­ates that more could be done to pre­vent and mit­ig­ate against ex­pens­ive time-con­sum­ing dis­putes.
