As the major gas resource of the West-East Gas Transmission Project, Kela 2 gas field plays an important role in the natural gas industry development and social demand in China. After 17 years development, annual gas production of Kela 2 gas field is stable in over 5 billion cubic meters, which has great reference value for the other gas field’s development. Kela 2 gas field is in the middle-late development period at present, some gas wells experienced water flooding in advance, which has resulted in a productivity decrease. Main challenges at current development period are development scheme adjustments such as water invasion prevention, water invasion control, production allocation optimization, and the conventional geological modeling cannot meet the scale requirement for the development scheme adjustment. By using the fine scale geological modeling techniques, it could provide a basis for the study of remaining reserves distribution, horizontal well deployment, water control and drainage scheme design.

Composting is proved to be environment friendly effective management option for the increasing volume of coffee wastes generated and causing significant environmental degradation in developing countries. In view of this, the quality of composts produced from coffee pulp with locally available organic matter following the windrow method was examined based on four treatments in randomized complete block design (4x3). The study involved determining some physicochemical parameters at 25, 55 and 80 days of composting. Mean values of bulk density, moisture content, pH, electric conductivity, organic matter, total organic carbon, total nitrogen, total phosphorous, total potassium and carbon to nitrogen ratio ranged from 483.6 kg/m –487.11 kg/m3, 50.74%–52.43%, 7.45-8.36, 3.08 mS/cm-3.42 mS/cm, 45.26%-46.99%, 26.19%-27.27%, 1.54%-1.61%, 0.41%-0.59%, 0.75%-1.15% and 17.5-18.44, respectively. Bulk density, total nitrogen, total phosphorous and total potassium increased with composting time in contrast to moisture content, organic matter, total organic carbon and C/N. pH and electrical conductivity initially increased but decreased at final stage. Mean physicochemical parameters of matured composts fell within the range of acceptable limits set by different countries guidelines. All parameters were not significantly different (p>0.05) except moisture content, pH and total potassium as compared to within treatments (p<0.05). The results revealed that a mixture of 50% coffee pulp,20% cow dung, 20% enset leaf and 10% top soil is more preferable to produce quality compost and consequently protect the environment.
