The ever-expanding Formate Technical Manual (aka the Formate Bible) has grown once again. This time with a whole section dedicated to formate brines's compatibility with shales.

Latest figures show that after just seven years of full production, formate brines have helped deliver close to 90% of estimated recoverable reserves from Huldra and Tune, two North Sea HPHT gas condensate fields.

Cesium formate brine delivers exceptional reservoir visualisation benefits by improving the acquisition and interpretation of the data generated by acoustic, resistivity and nuclear logging tools run on LWD and wire line.

In a concerted drive to increase its non-associated gas production, Saudi Aramco has engaged in a lengthy campaign of drilling slim-hole wells with long horizontal sections through Khuff and Pre-Khuff gas reservoirs.

After six years combating pressures of 14,000 psi and temperatures of 350°F (177°C) the production string was pulled from the High Island A-5 well #1 HPHT well in the Gulf of Mexico. Remarkably, the identification markings on the pipe were still intact.

Three newly published papers further our insight into formate brines and how they are best used in the oilfield.

A DOE-funded research programme into deep drilling optimisation has revealed that low-solids drilling fluids based on cesium formate brine can improve rates of penetration (ROP) by 100% under high-pressure conditions.

New tool developed by Gaia Consulting of Finland uncovers hidden costs of well completion and workover brines.

A question asked for the last 12 years has finally been answered. Why are the low levels of formation damage measured in HPHT gas wells after exposure to high-density formate brines sometimes not reproduced in laboratory coreflood tests?
