Abstract

The use of mud in the oil and gas industry is one of the most important parts of the drilling system, because drilling mud must be given special attention in order to expedite a drilling process. Barriers that often occur due to the presence of a layer of shale/clay reactiveIn order for the drilling mud to function properly and optimally, the rheology of the drilling mud is given special attention during the drilling process. In this study PHPA (Partially Hydrolyzed Polyacralamide) as a synthetic polymer mud is very suitable for use in formations that have rock types of laminar shale, clay and limestone, especially rocks that have sloughing shale and clay swelling highThis mud is also classified as an inhibitory systemforshale without reducing the role of the material as a mud former. While in the extraction of green grass jelly (Cyclea Barbata Miers) it is also used as a polymer (biopolymer) because it has polysaccharides where polysaccharides are carbohydrates composed of thousands of monosaccharides which function as texture and viscosity which will be used as the basic polymer material for making sludge. Extraction results of green grass jelly leaves (Cyclea Barbata Miers) at a concentration of 0.5 gram of 347 ml, then a concentration of 1 gram of 335 ml, then a concentration of 1.5 gram of 331 ml and at a concentration of 2 grams of 327 ml. Observation of laboratory test results on drilling mud rheology such as density, viscosity, gel strengthviscosity plastic, yield point, shear stress and shear rate. At the yield point there was a very drastic decrease with each addition of concentration in sample I grass jelly leaf sludge of (-0.1 lb/1000ft²), sample II grass jelly leaf (-0.2 lb/1000ft²), sample III grass jelly leaf (-0.5 lb/1000ft², sample IV grass jelly leaves increased by (0.2 lb/1000ft²) so that it can be said that the concentration used was very low so that the use of grass jelly leaves in this study as drilling mud can be said to be unfit for use.
