METHOD FOR DEVELOPMENT OF GAS AND GAS-CONDENSATE DEPOSITS Russian patent published in 1999 - IPC

FIELD: oil and gas production industry. SUBSTANCE: according to method, performed at initial period of deposit development are geophysical investigations. All required producing wells are drilled over peripheral part of deposit or simultaneously with drilling these producing wells in peripheral part of deposit, also drilled are top-priority producing wells in dome part of deposit. Determined is bed pressure of productive bed. At reduced value of current bed pressure due to development of deposit as compared with initial bed pressure of productive bed, additional producing wells are drilled in dome part of deposit. Application of aforesaid method ensures retention of filtration and injectivity properties of beds, prevents creation of depression funnel in dome part of deposit, and effects cleaning of well zone infested with sedimentations. EFFECT: high efficiency. 1 cl, 3 dwg
